Chevalierinol A and B, two new neolignan sesquiterpenoids from .

Two new neolignan sesquiterpenoids, chevalierinol A (1) and chevalierinol B (2), were isolated from the ethyl acetate extract of leaves, together with twelve known compounds (3-14). Their structures were elucidated by analysis of spectroscopic data including 1D, 2D and mass spectra and compared with the reported data. Compounds , , , , , were evaluated for their inhibitory effect against lipopolysaccharide (LPS)-induced nitric oxide (NO) production in RAW264.

ytotoxic Constituents of Mallotus microcarpus.

A new 3-methoxybenzensulfonic acid 4-0-0-D-glucopyranoside (1), and ten known compounds (2-11) were isolated from the methanolic extract of the stems of Mallotus microcarpus. The cytotoxicity of the isolated compounds was evaluated by the MTT method. 3-Methoxybenzensulfonic acid 4-Ο-β-D- glucopyranoside (1) and methyl salicylate 2-rutinoside (5) showed strong cytotoxicity against EGFR-TKI-resistant human lung cancer A549 cells in comparison with camptothecin.

Flavonoids from Anoectochilus annamensis and their Anti-inflammatory Activity.

One new flavonol diglycoside, 4',5-dihydroxy-3,3',7-trimethoxyflavone 4'-O-α-L-rhamnopyranosyl-(1 --> 6)-β-D-glucopyranoside (1), and two known compounds (2-3) were isolated from the methanolic extract of Anoectochilus annamensis Aver. aerial parts. The effects were evaluated of all isolated compounds (1-3) on LPS-induced production of the inflammatory mediator nitric oxide (NO) by RAW264.
