Abstract

Flavonol compounds, quercetin (1) and quercetin-3-O-?-D-glucopyranoside (2) have been isolated from the ethyl acetate extract of Lygodium microphyllum leaves. The chemical structures of flavonol compounds were identified based on spectroscopic data and by comparison of spectral data obtained previously. The discovery of flavonol compounds in Lygodium microphyllum was shown in this study for the first time.

Abstract

Six flavonoid compounds, kaempferol (1), quercetin (2), acacetin (3), quercetin-3-O-β-D-glucopyranoside (4), kaempferol-3-O-β-D-glucopyranoside (5), and isorhamnetin-3-O-β-D-glucopyranoside (6), were isolated from the methanol extract of the Lygodium microphyllum herb. The chemical structures of compounds 1-6 were identified on the basis of spectroscopic evidence and comparison with previously reported spectral data. Compounds 1-6 were isolated for first time from this plant. Their antioxidant activity against DPPH (2,2-Diphenyl-1-picrylhydrazyl) was evaluated. Among the compounds, quercetin (2) showed high antioxidant activity with IC50 values of 6.94 ± 0.03 μg/mL.

Abstract

A known naphthalene, isoeleutherol (1), was isolated from the herb ofLygodium microphyllum. The chemical structure of 1 was determined on the basis of spectroscopic data mainly UV, IR, HRTOFMS, 1D-and 2D-NMR spectroscopy, aswell as by comparing with compounds previously reported. Isoeleutherol was isolated from this plant for the first timeand showed moderate antioxidant activity against DPPH (2,2-diphenyl-1-picrylhydrazyl) with IC50 value of 53.96 ± 2.87 μg/mL.

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

Two mixtures of flavanoid compounds (1 and 2), a mixture of catechin (1a) and epicatechin (1b), and a mixture of gallocatechin (2a) and epigallocatechin (2b), were isolated from the active fraction of the stem bark of Aglaia elliptica methanol extract. The chemical structure of the compounds was identified with spectroscopic data, including UV, IR, NMR (1H, 13C, DEPT 135°, HMQC, HMBC, 1H-1H COSY), and MS, and additionally compared with previously reported spectral data. All compounds were evaluated for their cytotoxic effects against P-388 murine leukemia cells. Compound 2 showed cytotoxicity against the P-388 murine leukemia cell, with an IC50 value of 7.79 µg/mL, but compound 1 was found not to be active (more than 100 µg/mL).

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.
