Abstract null null Four new triterpenoids (1-4), along with five known triterpenoids (5-9), were isolated from the bark and twigs of Schima crenata. Their structures were elucidated by the use of extensive spectroscopic methods (UV, IR, HR-ESI-MS, 1D and 2D NMR). Most of the compounds were evaluated for their cytotoxicity against the A375, A549, and LoVo cancer cell lines. Compounds 4, 8, and 9 displayed inhibitory activity against three tumor cell lines with IC50 values ranging from 3.63 ± 1.86...

Abstract null null Three new compounds (1‒3), including a phenylpropanoid (1), a bistetrahydrofuran lignin (2), and a lignan dimer (3), and seven known lignans (4‒10), were isolated from an EtOH extract of the aerial parts of Triadica rotundifolia. The structures of the new compounds were elucidated by comprehensive spectroscopic analyses. New compounds 1−3 were evaluated for their antineuroinflammatory and antioxidant activities. Research on the antineuroinflammatory activity suggested that com...

Abstract null null Three new steroidal sapogenins, 3β,8β,14β-trihydroxycarda-5,20(22)-dienolide (1), (20R)-12β,20-epoxy-3β,8β,14β-trihydroxy-17α-pregn-5-en-17-yl 4-hydroxy-3-methoxybenzoate (2), and 3,20-dioxo-8β,14β,17β-trihydroxy-17α-pregn-5-en-12β-yl 4-hydroxybenzoate (3), along with four known C21-steroidal sapogenins (4-7) were isolated from the hydrolysate of Cynanchum otophyllum roots. Among them, compound 1 harbouring a rare β-OH at the C-8 position in the cardenolide skeleton, was ident...

Abstract null null The first phytochemical study of the aerial parts of Maytenus erythroxylon Reissek resulted in the isolation of five triterpenes, two with a lupane skeleton: 29-norlupan-3,20-dione (1) and 30-hydroxy-20 (29) -lupen-3-one (2) and three with friedelane skeleton: 3,4-secofriedelan-3-oic acid (3), 3-oxo-30-hydroxyfriedelane (4) and 3β-Hydroxyfriedelane (5), where the compound (1) is reported for the first time in the Maytenus genus. The structures were identified through the analy...

Abstract null null Sixteen non-steroidal compounds including four amides, six lignans, two sesquiterpenoids and three flavonoids, were isolated from the 80 % ethanol extract of whole plants of Solanum lyratum Thunb. Their structures were assigned based on analyses of extensive spectroscopic data (including MS, 1D/2D NMR and ORD) or comparisons of the NMR data with those reported. Among them, there were a new lignan namely isolariciresinol-9-acetate (5), a new natural amide compound (E)-N-(2-hydr...
