Abstract

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 mg/mL, respectively.

Abstract

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-1H-COSY 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

Abstract

Plants belonging to the Chisocheton genus are a rich source of tetracylic triterpenoids with diverse biological activities. Two triterpenoid compounds,dammar-20,24-dien-3-one (1) and 3β-hydroxy-tirucall-7-en (2) were isolated from the stembark of Chisocheton celebicus. The chemical structures of compounds 1 and 2 were identified by spectroscopic data, including IR, NMR (1H, 13C, DEPT 135°, HMQC, HMBC, 1H-1H COSY), and MS, and they were compared with previously reported spectral data. Compounds 1 and 2 were evaluated for their cytotoxic effects against P-388 murineleukemia cells. The compounds showed cytotoxicity against P-388 murine leukemia cells, with IC50 values of 30.2 and 4.3 μg/mL, respectively.

Abstract

Chisocheton is a large source of limonoids with various pharmacological effects, such as antiviral, antibacterial, antimalarial, antifungal, and cytotoxic activities. This study aimed to isolate, elucidate, and evaluate the cytotoxicity of limonoids from C. pentandrus stembarks. Isolation was carried out using various separation methods including extraction and column chromatography. Spectral data were analyzed by FT-IR, UV, DEPT 135°, 1H, 13C-NMR, and HRTOF-MS and compared with those previously reported to determine the chemical structure.The obtained limonoids were lasiocarpine (1), lasiocarpine B (2), pentandricine (3), and 16β-hydroxydysobinin (4); all of which were successfully isolated from C. pentandrus for the first time. The cytotoxic activity of these limonoids were also evaluated against Michigan Cancer Foundation-7 (MCF-7) breast cancer cells using PrestoBlue method. Lasiocarpine A revealed the strongest cytotoxicity with an IC50 of 42.62 µM in moderate level.
