Pengaruh Pemberian Ekstrak Temulawak (Curcuma xanthorrhiza) dalam Mengatasi Kelelahan Otot dengan Parameter Uji Ketahanan Renang dan Kadar Glutation = Effect of Javanese Turmeric Extract (Curcuma xanthorrhiza) in Overcoming Muscle Fatigue based on Parameters of Forced Swimming Test and Glutathione Levels

"Temulawak telah banyak digunakan sebagai obat tradisional oleh masyarakat Indonesia. Tanaman ini berpotensi membantu mengatasi lelah otot karena senyawa utamanya yaitu xantorizol memiliki aktivitas antioksidan yang mampu mengurangi radikal bebas berlebih yang terbentuk saat melakukan aktivitas berat. Penelitian ini dirancang untuk mengetahui pengaruh xantorizol terhadap kadar glutation pada mencit diinduksi lelah dengan metode FST. Kontrol positif diberikan taurin (T) dosis 700 mg/kg BB sebagai obat referensi. Kontrol negatif diberikan CMC-Na 1% (C). Kelompok dosis dibagi menjadi tiga, yaitu N10 (ekstrak NADES dosis 10 mg XTZ/kg BB), N25 (ekstrak NADES dosis 25 mg XTZ/kg BB), dan E10 (ekstrak etanol dosis 10 mg XTZ/kg BB). Pemberian dosis dilakukan selama 28 hari. Pada hari terakhir, mencit dilakukan FST untuk selanjutnya dibedah dan diambil jaringan hati untuk pengukuran kadar glutation. Lama waktu berenang setelah perlakuan N10, N25 dan T berbeda signifikan dengan sebelum perlakuan (p<0,05). Lama waktu berenang setelah perlakuan N10, N25, dan T tidak terdapat perbedaan bermakna namun berbeda signifikan dengan C (p<0,05). Kadar GSH N10 dan N25 signifikan lebih tinggi dibandingkan C. Rasio GSH/GSSG N10, N25, dan T signifikan lebih tinggi dibandingkan C (p<0,05). Dapat disimpulkan bahwa xantorizol pada ekstrak NADES temulawak membantu mengatasi lelah otot diinduksi stres oksidatif akibat aktivitas berat dan memiliki efek antilelah yang menjanjikan pada dosis XTZ 10 mg/kg BB dan 25 mg/kg BB.

Javanese Turmeric has been widely used as traditional medicine in Indonesia. This plant has potential to help overcome muscle fatigue because its main compound, xanthorrhizol, have antioxidant activity that reduce excess free radicals formed when the body performs high-intensity activities. The present study was designed to investigate the effect of xanthorrhizol on glutathione levels in fatigue-induced mice using the FST method. Positive control group was given taurine (T) at dose 700 mg/kg BW as a reference drug. Negative control group was administered 1% CMC-Na (C). The dosage groups were divided into three, N10 (NADES extract 10 mg XTZ/kg BW), N25 (NADES extract 25 mg XTZ/kg BW), and E10 (ethanol extract 10 mg XTZ/kg BW). Dose was given for 28 days. On the last day, FST was carried out in mice, then they were dissected and liver tissue was taken to measure glutathione levels. The swimming time after treatment in N10, N25, and T groups was significantly different from before treatment (p<0,05). The swimming time after treatment in N10, N25, and T groups was significantly different from C group (p<0.05). GSH levels of N10 and N25 groups were significantly higher than C groups. Ratio of GSH/GSSG of N10, N25, and T groups was significantly higher compared to C group (p<0.05). This study concludes that xanthorrhizol in NADES extract can help overcome muscle fatigue induced by oxidative stress due to high-intensity activities and has a promising anti-fatigue effect at XTZ doses of 10 mg/kg BW and 25 mg/kg BW."

Pengaruh laktat dan H+ terhadap timbulnya kelelahan otot rangka Rona sp pada perangsangan kontruksi submaksimal = The influence of lactate and H+ emerging muscle fatigue in Rana spat submaximal stimulation

"ABSTRAK

Latar belakang: Kelelahan (fatigue) adalah suatu fenomena fisiologis teljedinya

penurunan toleransi terhadap kerja flsik. Penyebabnya sangat spesiflk bergantung pada

karakteristik kerja tersebut. Ada dua pendapat yang menjelaskan timbulnya kelelahan

otot pada olahraga dengan intensitas tinggi dan durnsi singkat. Pertama, bahwa

penimbunan asam laktat merupakan penyebub timbulnya kelelahan otot, hal ini

disebabkan pemenuhan kebutuhan energi bergantung pada sistem fosfagen dan glikolisis

anaerob dan jalur metabolisme int menghasilkan produk samping yaitu asam laktat.

Dengan meningkatnya ketergantungan energi dari gHkolisis anaerob menyebabkan

terjadinya akumulasi asam laktat.

Pada pendapat kedua, kelelahan timbul akibat penimbunan It bebas yang berasal dari

basil Hidrolisis ATP dan glikolisis anaerob pada otot yang aktif. Kedua proses ini

menghasi!kan H+ bebas. Dengan makin meningkatnya intensitas dan kebutuhan akan

ATP, maka proses glikolisis anaerob dan ATP hidrolisis semakin meningkat, maka

akumulasi H+ bebas tersebut akan menimbulkan kelelahan otot.

Tujuan: Bagaimanakah pengaruh 1-F dan laktat terhadap timbulnya kelelahan otot yang

ditandai dengan menurunnya kekuatan kontraksi dari otot rangka tersebut?

Metode: Penelitian ini menggunakan 3 kelompok perlakuan. Otot gastrocnemius Rana

sp di rendarn dalam larutan perlaknan yang berbada yaitu sodium laktat (kelompok 1),

asam laktat (kelompok 2) dan asam sitrat (kelompok 3) selama 30 menit. Otot yang Ielah

direndam kemudiao dirangsang dengan kontraksi submaksimal dengan frekuensi 5 Hz

dan voltase 20 volt. Gambatan kontraksi direkam dengan menggunakan

mekanomiogram. Dihitung durasi mulai awal konttaksi hingga timbulnya penurunan

kekuatan kontraksi 50%. Data dianalisis dengan uji ANOVA.

Hasil: Terdapat perbedaan yang bermakna antara waktu kelelahan yang ditimbulkan

oleh sodium laktat dibandingkan dengan asam laktat (P<0,0T32809-Fanny septiani farhan5), Terdapat perbedaan yang

bermakna aot:ara waktu kelelahao yang ditimbulkan oleh sodium laktat dibandingkan

dengan asam sitrat (P<0,05), dan terdapat perbedaan yang bennakna ant:ara waktu

kelelahan yang ditimbulkan oleh asam laktat dibaodingkan dengan asam sitrat (P<0,05),

sehingga urutan timbulnya kelelahan dari yang tereepat hingga yang terlarna adalah asam

sitrat, asam laktat dan natrium laktat.

Kesimpulan: H+ merupakan faktor utama terhadap timbulnya kelelahan otot pada otot

rangka Rana sp.

Abstract

Background: Fatigue describes a condition in which a muscle is no longer able to

generate or sustain the expected power output. Fatigue is influenced by the intensity and

duration of the contractile activity. Multiple factors have been proposed to play a role in

fatigue. The popular opinion says that the accumulation of lactic acid as the main cause

of fatigue. During intense exercise, muscle and blood lactate can rise to very high levels.

Lactic acid becomes accumulated, has a direct detrimental effect on muscle performance.

The second opinion show that an increase concentration of hydrogen ions and a decrease

in pH (increase in acidity) within muscle or plasma, causes fatigue. The accumulation of

hydrogen ion release from glycolysis and ATP hydrolysis. The cell buffering capacity is

exceeded and fatigue developed.

Aims: The present study was designed to evaluate the role of W and lactate· in causing

muscle fatigue.

Design: the research uses 3 groups of treatment. Gastrocnemius muscle of Rana sp is

submerge in 3 different solutions. Sodium lactate (group 1), lactic acid (group 2) and

citric acid (group 3) for 30 minutes. The muscle is being stimulated using stimulator in

sub maximum contraction with frequency 5 Hz and 20 volt. the duration of fatigue is

observed from the initiation of contraction until 50% reduction of the muscle

contraction. Data is analyzed with ANOVA.

Result: The result of analysis showed that there were statistical differences on duration

of fatigue between sodium lactate and lactic acid, between lactic acid and citric acid, and

between lactic acid and citric acid (P

Conclusion: W accumulation plays big role in emerging muscle fatigue."

"Temulawak (Curcuma xanthorrhiza Roxb) merupakantanaman obat Indonesia yang mengandung senyawa kurkuminoid dan xantorizol yang memiliki aktivitas biologis yang luas. Natural Deep Eutectic Solvent (NADES) merupakan pelarut hijau alternatif yang memiliki dampak minimal untuk lingkungan karena sifatnya yang biodegradable.Penelitian ini bertujuan untuk mengevaluasi kemampuan menarik senyawa kurkuminoid dan xantorizol yang memiliki polaritas berbeda dengan pelarut NADES menggunakan metode ekstraksi berbasis utrasonik (UAE) yang dibandingkan dengan ekstraksi maserasi menggunakan pelarut etanol. Setelah dilakukan pengujian terhadap 3 kombinasi NADES, kombinasi NADES terpilih diekstraksi dengan 3 variabel bebas hingga dicapai kondisi optimum menggunakan rancangan Response Surface Methodology (RSM). Variabel bebas pada RSM yaitu penambahan air pada NADES (10, 20, 30%), waktu ekstraksi (10, 20, dan 30 menit), dan rasio pelarut terhadap serbuk (15, 20, 25 mL/g). Penetapan kadar kurkuminoid dan xantorizol dilakukan dengan Kromatografi Cair Kinerja Tinggi (KCKT) dengan fase gerak 0,07% asam format–asetonitril (45:55 v/v) lalu dideteksi pada panjang gelombang 425 nm untuk kurkuminoid dan 275 nm untuk xantorizol. Dari hasil analisis, kondisi ekstraksi optimal dihasilkan dari kombinasi NADES kolin klorida-gliserol (1:1) pada variasi 8 dengan kondisi penambahan air pada NADES sebanyak 10%, waktu ekstraksi 20 menit, dan rasio pelarut terhadap sampel 25 mL/g. Kondisi tersebut menghasilkan kadar kurkuminoid sebesar 7,32 mg/g dan kadar xantorizol sebesar 2,01 mg/g. Berdasarkan hasil penelitian, UAE-NADES lebih efektif dalam menarik senyawa kurkuminoid sebesar 7,32 mg/g dan maserasi-etanol lebih efektif dalam menarik senyawa xantorizol sebesar 12,61 mg/g. Kondisi optimum dipilih berdasar solusi RSM dengan kadar kurkuminoid sebesar 4,952 mg/g dan kadar xantorizol sebesar 0,694 mg/g.

Javanese turmeric contains curcuminoid and xanthorrhizol that have wide range of biological activities. Natural Deep Eutectic Solvents (NADES) is an alternative green solvent that has minimal impact on the environment due to its biodegradable nature. This study aimed to evaluate the ability to extract curcuminoids and xantorizol that have different polaritieswith NADES using Ultrasound-Asissted Extraction (UAE) compared to conventional maceration extraction using ethanol. After testing 3 NADES combinations, the selected NADES was extracted with 3 independent variables until the optimum conditions were achieved using the Response Surface Methodology (RSM) design.The independent variables used were the addition of water to NADES (10, 20, 30%), extraction time (10, 20, and 30 minutes), and the ratio of solvent to powder (15, 20, 25 mL/g). The levels of curcuminoids and xanthorrhizol were determined using High-Performance Liquid Chromatography (HPLC) with a mobile phase of 0.07% formic acid–acetonitrile (45:55v/v) then detected at a wavelength of 425 nm for curcuminoids and 275 nm for xanthorrhizol. From the analysis results, the optimal extraction conditions resulted from the combination of NADES choline chloride-glycerol (1:1) at run 8 with the conditions of adding 10% of water to NADES, 20 minutes extraction time, and solvent to sample ratio 25 mL/g. This condition resulted in curcuminoid levels of 7.32 mg/g and xantorizol levels of 2.01 mg/g. Based on the results of the study, UAE-NADES was more effective in attracting curcuminoid of 7.32 mg/g and maceration-ethanol was more effective in attracting xanthorizolof 12.61 mg/g. The optimum conditions were selected based on the RSM solution, with curcuminoid levels of 4.952 mg/g and xanthorizol levels of 0.694 mg/g."

Independent variables used for optimization are IL concentration (0.05; 0.1; 0.15M), time extraction (10; 12.5; 15 minutes) and ratio of solvent to powder (15; 20; 25 mL/g). All variables were designed by using Response Surface Methodology (RSM). Curcuminoid and xanthorrhizol quantification was done using HPLC UV-Vis with mobile phase composition of acetonitrile (A) and 0.07% formic acid on water (B) with gradient elution program 45–85% (A): 0-60 min, 65 – 100% (A): 60-75 min, 100% (A): 75-80 min and was detected on a wavelength of 425 (curcuminoid) and 275 (xanthorrhizol). The results showed that the highest curcuminoid content obtained was 8.709 mg/g with IL concentration 0.05M; time extraction 12 minutes and a ratio of solvent to powder 1:25 g/mL. While the highest xanthorrhizol content obtained was 14.099 mg/g with IL concentration 0.05M; time extraction 14 minutes and a ratio of solvent to powder 1:24.5 g/mL. Based on the result, IL-UAE is more effective to attract curcuminoid and xanthorrhizol than the conventional method. Maceration using 96% ethanol of javanese turmeric rhizome only gave results of 4.92 mg/g for curcuminoid and 12.467 mg/g for xanthorrhizol."

Pengaruh Tempat Tumbuh Tanaman Ekstrak Etanol Temulawak (Curcuma xanthorrhiza Roxb.) Sebagai Agen Inhibisi Biofilm Candida albicans In Vitro = Does herbal therapeutics cultivation site affect in vitro Candida albicans biofilm inhibition? â a study on Curcuma xanthorrhiza Roxb. ethanolic extract

"Background: One of the major challenges in developing an antifungal against Candida albicans as a therapeutic strategy for oral candidiasis is its resistance towards antimicrobial agents. Currently, medicinal plants are continuously being developed as a therapeutic agent, including Javanese turmeric (Curcuma xanthorrhiza Roxb.), an Indonesian plant widely used as a traditional medicine. Its main active compound, xanthorrhizol, as well as the Javanese turmeric Ethanol Extract (EET) had been reported to have antifungal properties. However, extract quality as well as cultivation site of a medicinal plant may affect its’ effectivity as a therapeutic agent. Objective: To analyze the influence of Javanese turmeric cultivation site against its’ ethanolic extract effectivity in inhibiting C. albicans biofilms. Methods: 2 Javanese turmeric ethanolic extract were collected from different cultivation sites, which were Bogor, West Java and Malang, East Java. The extracts were tested for inhibitory activity against C. albicans biofilm using OD600, TPC, and MTT assay measurements. Results: There were concentration differences of xanthorrhizol content in between the two extracts. Despite so, both extracts showed insignificant MBIC50 differences at roughly 0,10 µg/mL, while their MBIC90 were measured to be constant at all biofilm development phases, at 0,30 µg/mL. Conclusion: The different cultivation site of Javanese turmeric in Java island does not influence the effectivity of JtET in inhibiting C. albicans biofilm.

Background: One of the major challenges in developing an antifungal against Candida albicans as a therapeutic strategy for oral candidiasis, an opportunistic oral fungal infection, is its resistance towards antimicrobial agents. Currently, medicinal plants are being developed as a therapeutic agent, including Javanese turmeric (Curcuma xanthorrhiza Roxb.), an Indonesian plant widely used as a traditional medicine. Its main active compound, xanthorrhizol, is known to have antifungal properties. However, extract quality as well as cultivation site of a medicinal plant may affect its’ effectivity as a therapeutic agent. Up until now, there hasn’t been any datas that explain how these factors affect Javanese turmeric ethanolic extract as a C. albicans strategy. Objective: To analyze the effect of Javanese turmeric cultivation site against its’ ethanolic extract ability to inhibit C. albicans biofilms. Methods: 2 Javanese turmeric ethanolic extract were collected from different cultivation sites, which were Bogor, West Java and Malang, East Java. The extracts were tested for inhibitory activity against C. albicans biofilm using OD600, TPC, and MTT assay measurements. Results: There were concentration differences of xanthorrhizol between the extracts. Despite so, both extracts’ MBIC50 differences were insignificant at roughly 0,10 µg/mL, while their MBIC90 were measured to be constant at all biofilm development phases, at 0,30 µg/mL. Conclusion: There were no significant differences between the MBICs of both extracts against C. albicans biofilm. More research needs to be done to confirm the role of other factors such as storage time on their MBIC."

Efek dari Nanocurcumin dan Curcumin dalam Modulasi Marker Stres Oksidatif di Model Tikus dengan Kanker Rahim yang diobati dengan Cisplatin = The Effect of Nanocurcumin and Curcumin in the Modulation of Oxidative Stress Markers in Ovarian Cancer Models treated with Cisplatin in Rats

"Kanker ovarium merupakan kanker ginekologi tersering kedua, setelah kanker serviks dan juga merupakan salah satu jenis kanker dengan angka insidensi tertinggi pada wanita Indonesia. Cisplatin adalah salah satu jenis kemoterapi yang sering digunakan dalam terapi kanker ovarium. Cisplatin bekerja dengan memproduksi oksidatif stress untuk melawan sel kanker, akan tetapi mekanisme ini berpotensi untuk membahayakan tubuh, seperti menyebabkan toksisitas pada organ seperti hati dan ginjal, maupun toksisitas sistemik. Untuk mengurangi efek samping dari cisplatin, curcumin dapat ditambahkan. Curcumin juga dapat meningkatkan efek anti kanker cisplatin, akan tetapi bioavailabilitas curcumin masih cukup rendah. Oleh karena itu, kelompok penelitian kami mengembangkan curcumin dalam bentuk nano partikel, atau Nanocurcumin dengan ukuran 11,5 nm, yang sudah terbukti meningkatkan bioavailabilitas kurkurmin dalam tubuh. Penelitian ini adalah penelitian in vivo pada tikus Wistar betina. Penelitian ini mengobservasi efek anti kanker kemoterapi terhadap stress oksidatif yang dihasilkan oleh efek samping pengobatan kemoterapi dengan melihat konsentrasi SOD, GSH dan MDA dari sampel darah yang diambil dari vena di ekor tikus. Hasil yang diperoleh peneliti adalah tidak signifikan secara statistik, sehingga disimpulkan bahwa bahwa curcumin dan nanocurcumin tidak memodulasi SOD, GSH dan MDA pada terapi kanker ovariaum yang mendapat terapi cisplatin.

Ovarian cancer is the second most common gynaecological cancer, and is also one of cancer that has the highest incidence level in Indonesian women. One of the main chemotherapy that is used to treat ovarian cancer therapy is cisplatin. Cisplatin works by generating oxidative stress to fight the cancer, however this would act as double edged knife. While generating oxidative stress is good for the therapeutic purpose, it would cause harm to the body, such as causing organ toxicity and systemic toxicity. To reduce the side effect of cisplatin, curcumin can be used. Curcumin also has an anti-cancer effect that can enhance the therapeutic effect of cisplatin. However, curcumin has a low bioavailability. To overcome this, our research group developed a nanosized curcumin, called Nanocurcumin, with the size of 11,5 nm, it has been proven to increase the bioavailability of curcumin in the body. This research is in an in vivo experiment on female Wistar rats. This research will observe the effect of anticancer co-chemotherapy on oxidative stress, by looking into GSH, SOD and MDA concentration from blood samples that were collected from the vein of the rat's tail. Results obtained for GSH, SOD and MDA were statistically insignificant (p>0,05). In conclusion, curcumin and nanocurcumin don't modulate GSH, SOD and MDA in ovarian cancer model in rats treated with cisplatin."
