Two new oleanane-type triterpenoids, named platycodonoids A and B (1, 2), together with five known saponins, including platycodin D (3), deapioplatycodin D (4), 3-O-β-D-glucopyranosyl polygalacic acid (5), 3-O-β-D-glucopyranosyl platycodigenin (6) and polygalacin D (7), were isolated from the roots of Platycodon grandiflorum. On the basis of spectral data and chemical evidence, the structures of the new compounds were elucidated as 2β,3β,23,24-tetrahydroxy-28-nor-olean-12-en-16-one (1) and 2β,3β,23,24- tetrahydroxy-28-nor-olean-12-en-16-one-3-O-β-D-glucopyranoside (2). Compounds 1–7 were evaluated for their in vitro anti-proliferative activity against the HSC-T6 cell line.
两种新的齐墩果烷型三萜类化合物,命名为桔梗类 A 和 B (1, 2),以及五种已知的皂苷,包括桔梗皂苷 D (3)、deapioplatycodin D (4)、3-O-β-D-吡喃葡萄糖基聚半乳酸 (5) )、3-O-β-D-吡喃葡萄糖基桔梗皂苷元 (6) 和远志 D (7),从桔梗的根中分离出来。根据光谱数据和化学证据,新化合物的结构被阐明为2β,3β,23,24-四羟基-28-nor-olean-12-en-16-one(1)和2β,3β, 23,24-四羟基-28-降-齐墩果-12-en-16-酮-3-O-β-D-吡喃葡萄糖苷(2)。评估了化合物 1-7 对 HSC-T6 细胞系的体外抗增殖活性。
