"The genus Aglaia is a a rich source of different compounds with interesting biological activities. A part of our continuing search for novel biologically active compounds from Indonesia Aglaia plants, the ethyl acetate extract of bark of Aglaia eximia showed significant antioxidant activity. Four antioxidant compounds, kaempferol (1), kaempferol-3-O-α-L-rhamnoside (2), kaempferol-3-O-β-D-glucoside (3) and kaempferol-3-O-β-D-glucosyl-(1→4)-α- L rhamnoside (4) were isolated from the bark of Aglaia eximia (Meliaceae). The chemical structures of compounds 1-4 were identified on the basis of spectroscopic datas including UV, IR, NMR and MS along with by comparison with those spectra datas previously reported. All compounds showed DPPH radical-scavenging activity with IC50 values of 1.18, 6.34, 8.17, 10.63 μg/mL, respectively."

"Three flavonoid compounds, kaempferol (1), kaempferol-3-O-α-L-rhamnoside (2), and kaempferol-3-O-β-D-glucosyl-α-L-rhamnoside (3), were isolated from the bark of Aglaia eximia (Meliaceae). The chemical structures of compounds 1?3 were identified with spectroscopic data, including UV, IR, NMR (1H, 13C, DEPT 135°, HMQC, HMBC, 1H-1HCOSY NMR), and MS, as well as a compared with previously reported spectra data. All compounds were evaluated for their cytotoxic effects against P-388 murine leukemia cells. Compounds 1?3 showed cytotoxicity against P-388 murine leukemia cells with IC50 values of 1.22, 42.92, and >100 mg/mL, respectively.

Senyawa Flavonoid dari Kulit Batang Aglaia eximia (Meliaceae). Tiga senyawa flavonoid, kaempferol (1), kaempferol-3-O-α-L-ramnosida (2), dan kaempferol-3-O-β-D-glukosil-α-L-ramnosida (3), diisolasi dari batang Aglaia eximia (Meliaceae). Struktur kimia senyawa 1?3 diidentifikasi berdasarkan data spektroskopi, meliputi UV, IR, NMR (1H, 13C, DEPT 135°, HMQC, HMBC, 1H-1H-COSY NMR), dan MS, serta perbandingan dengan data spektra yang diperoleh sebelumnya. Seluruh senyawa dievaluasi pengaruh sitotoksiknya terhadap sel murine leukimia P-388. Senyawa 1-3 menunjukkan aktivitas sitotoksik terhadap sel murine leukimia P-388 dengan nilai IC50 berturut-turut 1,22; 42,92, dan >100 mg/mL."
