摘要

A new carotane sesquiterpene glycoside, 3β-(2-hydroxypropan-2-yl)-6,8aβ-dimethyl-1β,2,3α,3aα,4,8a-hexahydroazulene-1α-O-β-D-glucopyranoside (polymorpholide-1-O-glucocside, 7), along with known compounds 2-[4′-phenyl]-2-hydroxy-ethanol (1), tyrosol (2), protocatechuic acid (3), vanilic acid (4), cimifugin (5), uracil (6), and 5,7-dihydroxychromone-2-carboxylic acid (8) were isolated from the leaves of Angelica polymorpha. Their structures were elucidated using spectroscopic method, including extensive 2D NMR techniques.
