Paparan sinar UV yang berlebihan merupakan salah satu faktor ekstrinsik penyebab terjadinya penuaan dini, yaitu akibat terbentuknya radikal bebas dan Reactive Oxygen Species (ROS). Rubus fraxinifolius Poir. terutama pada bagian daunnya terbukti secara in vitro memiliki sifat antipenuaan dengan cara mencegah aktivitas enzim elastase. Tujuan dari penelitian ini adalah menganalisis kadar total fenol, kadar total flavonoid, aktivitas antioksidan DPPH (1,1-difenil-2-pikrilhidrazil), FRAP (Ferri Reducing Antioxidant Power) dan ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) serta aktivitas penghambatan elastase dari ekstrak (hasil optimasi jenis daun dan optimasi metode ekstraksi) dan fraksi daun Rubus fraxinifolius, selanjutnya fraksi ter-aktif diformulasikan dalam sediaan gel. Penelitian diawali dengan optimasi jenis daun terlebih dahulu dengan cara ekstraksi terhadap daun tua dan daun muda secara Soxhlet, dan dievaluasi aktivitas antioksidan dan aktivitas penghambatan elastase. Selanjutnya dilakukan optimasi metode ekstraksi secara Soxhlet, Microwave Assisted Extraction (MAE) dan Ultrasound Assisted Extraction (UAE) kemudian dievaluasi aktivitas antioksidan dan aktivitas penghambatan elastase. Ekstrak teraktif selanjutnya dilakukan fraksinasi dengan n-heksana, etil asetat, dan aquadest. Fraksi teraktif dilakukan pengujian antioksidan dan aktivitas penghambatan elastase, kemudian diidentifikasi menggunakan LC-MSMS. Berdasarkan hasil optimasi jenis daun, ekstrak daun tua memiliki kinerja yang lebih baik dibandingkan dari daun muda dalam hal aktivitas antioksidan dan aktivitas penghambatan enzim elastase. Sedangkan hasil optimasi metode ekstraksi, UAE memberikan hasil terbaik untuk selanjutnya difraksinasi dan fraksi aquadest memberikan hasil terbaik aktivitas antioksidan dan aktivitas penghambatan enzim elastase. Formulasi gel fraksi aquadest dari metode ekstraksi secara UAE menunjukkan pada formula 1 dengan konsentrasi fraksi daun Rubus 3% memberikan hasil yang lebih baik dan stabil selama masa penyimpanan 12 minggu. ......Excessive exposure to UV light is one of the extrinsic factors that causes premature aging, which is due to the formation of free radicals and Reactive Oxygen Species (ROS). Rubus fraxinifolius Poir. especially in the leaves have antiaging in vitro properties by preventing the activity of elastase enzyme. The purpose of this study was to analyze total phenol levels, total flavonoid levels, antioxidant activity of DPPH (1,1-diphenyl-2-pikrilhidrazyl), FRAP (Ferri Reducing Antioxidant Power) and ABTS (2,2'-azino-bis(3- ethylbenzothiazoline-6-sulfonic acid) also elastase inhibitory activity of the extract (from optimizing leaf types and optimizing extraction methods) and Rubus fraxinifolius leaf fractions, then the most active fractions are formulated in Gel preparations. The research begins with optimizing leaf types first, by extraction old leaves and young leaves used Soxhlet method, and evaluated their antioxidant activity and elastase inhibition activity. Furthermore, optimization of extraction methods (Soxhlet, Microwave Assisted Extraction/ MAE and Ultrasound Assisted Extraction/ UAE) was carried out and then evaluated antioxidant activity and elastase inhibitory activity. Active extract then fractionated with n-hexane, ethyl acetate, and aquadest. The most active fraction was tested for antioxidant and elastase inhibitory activity, then identified using LC-MSMS. Based on the optimization of leaf types, old leaf extract has better performance than young leaves in terms of antioxidant activity and elastase enzyme inhibitory activity. While the optimization results of extraction method UAE gave the best results. Fractionation process gave aquadest fraction the best results for antioxidant activity and elastase enzyme inhibitory activity. The gel formulation of the aquadest fraction from the UAE extraction method showed that formula 1 with a concentration of 3% Rubus leaf fraction gave better and more stable results during a storage period of 12 weeks.

Lendir keong darat saat ini sudah digunakan sebagai sediaan kosmesetikal karena adanya dukungan ilmiah yang melaporkan bahwa lendir beberapa spesies keong darat memiliki bioaktivitas yang bermanfaat untuk kesehatan dan kecantikan kulit. Amphidromus palaceus adalah salah satu spesies keong darat native Indonesia yang memiliki tubuh relatif besar sehingga mudah untuk di koleksi lendirnya. Penelitian bioprospeksi lendir A. palaceus sebagai sediaan kosmesetikal belum banyak dilakukan sampai saat ini. Beberapa klaim kosmesetikal yang menarik untuk ditelusuri adalah pencarian agen pemutih dan anti kerut. Inhibisi tirosinase via jalur biosintesis melanin dapat digunakan sebagai klaim agen pemutih, sedangkan inhibisi elastase via jalur degradasi elastin dapat digunakan sebagai klaim anti kerut. Penelitian ini bertujuan untuk mengidentifikasi senyawa metabolit lendir A. palaceus, serta mengungkap potensinya sebagai inhibitor tirosinase dan elastase melalui penambatan molekuler. Identifikasi senyawa metabolit menggunakan instrumen UPLC-MS/MS, sedangkan penambatan molekuler menggunakan perangkat lunak AutoDock Tools 1.5.7 dan AutoDock 4.2. Penelitian ini berhasil mengidentifikasi 17 senyawa metabolit lendir A. palaceus dengan 10 senyawa dengan status terduga dan 7 senyawa dengan status terkonfirmasi.

Riset pencarian senyawa bioaktif yang memiliki aktivitas penghambatan terhadap enzim elastase dan antioksidan dalam menunda proses penuaan pada kulit terus diupayakan agar dapat dikembangkan menjadi kandidat agen anti-aging yang potensial. Tanaman mabolo (Diospyros blancoi A. DC.) merupakan tanaman asli Indonesia yang belum banyak dieksplorasi pemanfaatannya baik secara tradisional maupun ilmiah sebagai anti-aging. Penelitian ini bertujuan untuk mengidentifikasi senyawa bioaktif dari ekstrak metanol daun (EDM) atau ekstrak metanol kulit batang (EKM) tanaman mabolo yang memiliki aktivitas anti-elastase dan antioksidan teraktif. Ekstraksi daun dan kulit batang dengan pelarut metanol mengggunakan ultrasound assisted-extraction (UAE). Aktivitas anti-elastase dan antioksidan dari tiap ekstrak, fraksi, subfraksi, dan isolat dievaluasi. Hasil penelitian menunjukkan bahwa EKM memiliki aktivitas anti-elastase dan antioksidan lebih kuat dibanding EDM meskipun keduanya memiliki aktivitas yang sangat kuat dibawah 50 µg/mL. EKM sebagai ekstrak teraktif dilanjutkan fraksinasi padat-cair dan menghasilkan fraksi etil asetat kulit batang mabolo (FEKM) yang memiliki aktivitas anti-elastase dan antioksidan paling kuat dibandingkan dengan fraksi metanol kulit batang mabolo (FMKM) maupun fraksi heksan kulit batang mabolo (FHKM). FEKM sebagai fraksi teraktif difraksinasi lebih lanjut dengan kromatografi kolom menghasilkan 16 subfraksi etil asetat kulit batang mabolo (SEKM A-SEKM P). Hasil identifikasi isolat melalui FTIR dan NMR dibandingkan terhadap literatur. Isolat DB1 yang diperoleh dari isolasi SEKM N diduga asam galat, sedangkan isolat DB2 yang diperoleh dari isolasi SEKM L dan SEKM N diduga asam betulinat. Aktivitas anti-elastase isolat DB2 [IC50 = 8,62 µg/mL (18,88 µM)] lebih kuat dibanding DB1 (IC50 = 93,35 µg/mL (548,70 µM)]. Akan tetapi, aktivitas antioksidan isolat DB1 lebih kuat dibanding isolat DB2. Sementara itu, aktvitas antielastase isolat DB2 menunjukkan jenis inhibisi unkompetitif secara in vitro. Hasil interaksi secara in silico diprediksi isolat DB2 menghambat bukan pada sisi aktif enzim elastase (1B0F) dengan energi bebas ikatan sebesar -5,85 kcal/mol. ......Studies on the discovery of bioactive compounds that have inhibitory activity against elastase enzymes and antioxidants in delaying the skin's aging process are still being explored so that potential anti-aging agents could be developed. The mabolo plant (Diospyros blancoi A. DC.) is a native Indonesian plant that has not been widely explored for its traditional and scientific uses as anti-aging. This study aimed to identify bioactive compounds from leaf methanol extract (EDM) or stem bark methanol extract (EKM) of the mabolo plant that have the most active anti-elastase and antioxidant activities. Extraction of leaves and stem bark with methanol solvent using ultrasound assisted-extraction (UAE). Both the anti-elastase and antioxidant activities of each extract, fraction, subfraction, and isolate were evaluated. The results showed that EKM had stronger anti-elastase and antioxidant activities than EDM although both had very strong activities below 50 µg/mL. EKM as the most active extract was followed by solid-liquid fractionation and resulted in ethyl acetate fraction of mabolo stem bark (FEKM) which had the strongest anti-elastase and antioxidant activities compared to methanol fraction of mabolo stem bark (FMKM) and hexane fraction of mabolo stem bark (FHKM). FEKM as the most active fraction was further fractionated by column chromatography to obtain 16 ethyl acetate subfractions of mabolo stem bark (SEKM A - SEKM P). The results of isolate identification by FTIR and NMR were compared to the literature. Isolate DB1 obtained from SEKM N isolation was considered gallic acid, while isolate DB2 obtained from SEKM L and SEKM N isolation was considered betulinic acid. The anti-elastase activity of isolate DB2 [IC50 = 8.62 µg/mL (18.88 µM)] was stronger than DB1 (IC50 = 93.35 µg/mL (548.70 µM)]. However, the antioxidant activity of isolate DB1 was stronger than isolate DB2. Meanwhile, the anti-elastase activity of isolate DB2 showed an uncompetitive type of inhibition in vitro. In silico interaction results predicted DB2 isolate inhibits not on the active side of the elastase enzyme (1B0F) with a binding free energy of -5.85 kcal/mol.

Mikroalga Nannochloropsis sp. memiliki kandungan biomassa bervariasi, salah satunya protein. Hidrolisis protein menghasilkan peptida dan asam amino sehingga meningkatkan bioaktivitas dari protein. Penelitian ini bertujuan untuk mendapatkan protein hidrolisat dari mikroalga Nannochloropsis sp. serta mengetahui keamanan dan efektivitasnya sebagai produk kosmetik anti-aging. Protein hidrolisat mikroalga Nannochloropsis sp. (PHMN) diperoleh dari proses hidrolisis menggunakan enzim alkalase. PHMN dievaluasi perolehan rendemen, derajat hidrolisis, kandungan proksimat, asam amino serta aktivitas anti-elastasenya. PHMN diformulasikan menjadi sediaan emulgel, kemudian dievaluasi sifat fisikokimia dan stabilitasnya. Uji keamanan produk kosmetik PHMN dilakukan dan efektivitas produk kosmetik PHMN sebagai anti-aging dievaluasi dengan mengukur serat kolagen, elastisitas, dan kelembaban kulit relawan. Protein hidrolisat yang diperoleh memiliki nilai rendemen sebesar 25,77%±3,16% (b/b), derajat hidrolisis sebesar 36,73%, dan mengandung asam amino yang didominasi oleh asam glutamat, asam aspartat, dan leusin. Nilai konsentrasi penghambatan setengah maksimal (IC50) PHMN sebagai anti-elastase yaitu 244,43 mg/mL. Produk kosmetik PHMN menunjukkan stabilitas yang baik yaitu homogen dan kadar yang stabil setelah 24 minggu. Penggunaan produk kosmetik PHMN tidak menyebabkan iritasi dan meningkatkan serat kolagen, elastisitas, dan kelembaban kulit setelah 28 hari. Dari penelitian ini disimpulkan bahwa diperoleh protein hidrolisat dari mikroalga Nannochloropsis sp. serta produk kosmetik PHMN memiliki karakteristik yang baik, aman, dan efektif sebagai anti-aging ......Microalgae Nannochloropsis sp. contain various biomass composition including protein. Protein hydrolysis generate peptide and amino acids so that protein bioactivity improves. The purpose of study was to obtain protein hydrolysate from Nannochloropsis sp. microalgae, also assess its safety and efficacy as anti-aging cosmetic product. Nannochloropsis sp. protein hydrolysate (NPH) was obtained from microalgae through enzymatic hydrolysis using alcalase enzyme and characterized for yield, degree of hydrolysis (DH), proximate content, amino acids composition, and anti-elastase activity. NPH was formulated as emulgel, then evaluated for physical characteristics and stability. NPH cosmetic product was evaluated for safety and efficacy as anti-aging by measuring collagen fibers, elasticity, and moisture in volunteers. NPH was obtained with yield of 25.77±3.16% (w/w), DH value of 36.73%, and amino acids dominated by glutamic acid, aspartic acid, and leucin. Half-maximum inhibitory concentration (IC50) value as anti-elastase was 244.43 µg/mL. NPH cosmetic product showed good stability which homogenous and had stable protein content after 24 weeks storage. NPH cosmetic product usage did not cause skin irritation and increased collagen fiber, elasticity and moisture after 28 days. In conclusion, protein hydrolysate was obtained from Nannochloropsis sp. microalgae and NPH cosmetic product had good characteristic, safe, and effective as anti-aging.

Abstrak :
Penuaan dini pada kulit skin aging merupakan suatu permasalahan yang dapat disebabkan peningkatan aktivitas proteolitik elastase. Peningkatan aktivitas elastase menyebabkan pemecahan dan disorganisasi elastin pada jaringan ikat, sehingga dapat menurunkan elastisitas dan fleksibilitas pada kulit berupa keriput. Senyawa alami pada tumbuhan, khususnya polifenol terbukti dapat menghambat aktivitas elastase dan mencegah penuaan dini pada kulit. Daun Belimbing A. carambola merupakan bahan alam yang banyak mengandung polifenol dan memiliki banyak manfaat seperti antioksidan, antiinflamasi, hipoglikemi, antimikroba, dan lain sebagainya. Namun, belum terdapat penelitian yang membuktikan bahwa daun A. carambola memiliki aktivitas penghambatan terhadap elastase. Pada penelitian ini, akan dilakukan pengujian penghambatan aktivitas elastase pada fraksi air, etil asetat, dan n-heksana Daun A. carambola dari tiga daerah di Jawa Barat Depok, Sukabumi, dan Subang. Masing-masing fraksi diuji penghambatannya terhadap aktivitas elastase menggunakan microplate reader, kemudian dilakukan penetapan kadar fenol dan flavonoid total pada fraksi teraktif. Hasil uji penghambatan aktivitas elastase menunjukkan bahwa fraksi air daun A. carambola Depok merupakan fraksi teraktif dengan nilai IC50 160,36 g/mL. Kadar fenol dan flavonoid total pada fraksi air daun A. carambola Depok berturut-turut adalah 115,68 mg GAE / g fraksi dan dan 9,15 mg QE / g fraksi. ......Premature skin aging is a problem that can be caused by an increase in proteolytic activity of the elastase. Increased elastase activity causes breakdown and disorganization of elastin in connective tissue, thus reducing elasticity and flexibility in form of wrinkled skin. Natural compounds in plants, especially polyphenols have been shown to inhibit elastase activity and prevent premature aging of the skin. Star fruit 39s A. carambola leaves is a natural material that contains many polyphenols and has many benefits such as antioxidants, anti inflammatory, hypoglycemic, antimicrobial, and so forth. However, there is no studies have shown that A. carambola leaves have inhibitory activity against elastase yet. In this research, we will test the inhibition of elastase activity on the water, ethyl acetate and n hexane fractions of A. carambolas leaves. from three regions in West Java Depok, Sukabumi, and Subang. Each fraction was tested for its inhibition of elastase activity using microplate reader, then total phenol and flavonoid content was determined at the most active fraction. The result of inhibition test of elastase activity showed that water fraction of A. carambola lsquo s leaves Depok was the most active fraction with IC50 value 160.36 g mL. Total phenol and flavonoid content in water fraction A. carambola lsquo s leaves Depok were 115.68 mg GAE g fraction and 9.15 mg QE g fraction respectively.
