A new lignan glycoside from .

A new lignan glycoside, astrayunoside A (), along with eight known compounds (), were obtained from the methanol extract of roots of . All the compounds were obtained from for the first time. Their structures were elucidated by extensive spectroscopic analysis (1D and 2D-NMR, MS, UV, CD, and IR).

[Study on chemical constituents from rhizome of Rabdosia flavida].

Objective: To study the chemical constituents from the rhizome of Rabdosia flavida.

Methods: The compounds were isolated and purified by various chromatographic methods, and their structures were elucidated on the basis of spectral data and physicochemical properties.

Results: Ten compounds were obtained from ethyl acetate fraction of the 70% acetone extract of Rabdosia flavida rhizome and identified as ferruginol (1), dehydrocostuslactone (2), taraxasterol (3), oleic acid (4), ursolic cid (5), coniferyl aldehyde (6), oleanolic acid (7), 6,12, 15-trihydroxy-5, 8,11, 13-abietetra-7-one (8), 5α, 8α-epidioxyergosta-6,22-dien-3β-ol (9), and daucosterol (10).

A new schistosomicidal and antioxidative phenylpropanoid from Astragalus englerianus.

A new phenylpropanoid, (E)-2,3,4-trimethoxy-5-(1-propenyl)phenol (1), along with five known aromatic compounds (2-6), was isolated from the methanol extract of roots of Astragalus englerianus. Their structures were elucidated based on the analyses of extensive spectroscopic data and comparison of their physicochemical properties. Compounds 1 and 2 were evaluated schistosomicidal activities, and all the isolated compounds were tested for their antioxidant activities in vitro.
