Chemical Constituents from Roots of Achyranthes bidentata

Abstract:

Twelve compounds were isolated from the roots of Achyranthes bidentata Blume. On the basis of spectral data, they were identified as polypodine B (1), shidasterone (2), oleanolic acid (3), oleanolic acid 3-O-β-D-glucuronopyranoside-6′-O-methyl ester (4), chikusetsusaponin Ⅵa methyl ester (5), N-cis-feruloyltyramine (6), N-cis-feruloyl-3-methoxytyramine (7), N-trans-feruloyltyramine (8), N-trans-feruloyl-3-methoxytyramine (9), tianshic acid (10), (9E)-8,11,12-trihydroxyoctadecenoic acid methyl ester (11) and linoleic acid (12). Compounds 2, 6, 7, and 10-12 were obtained from the plant for the first time.
