A new unusual minor triterpenoid saponin, platycoside O (1), was isolated from the 75% EtOH extract obtained from the roots of Platycodon grandiflorum, together with four known saponins: platycoside M-3 (2), platycoside J (3), platycoside F (4) and platycoside B (5). The structure of 1 was determined as 3-O-β-D-glucopyranosyl-(1→6)-β-D-glucopyranosyl-2β,3β,16α,23-tetrahydroxyolean-12-en-24-methoxyl
从桔梗根的 75% EtOH 提取物中分离出一种新的不寻常的次要三萜皂苷,桔梗苷 O (1),以及四种已知的皂苷:桔梗苷 M-3 (2)、桔梗苷 J (3)、桔梗苷F (4) 和桔梗苷 B (5)。1 的结构确定为 3-O-β-D-吡喃葡萄糖基-(1→6)-β-D-吡喃葡萄糖基-2β,3β,16α,23-tetrahydroxyolean-12-en-24-methoxyl, 24-oxo -28-oic acid 28-O-β-D-xylopyranosyl-(1→4)-α-L-rhamnopyranosyl-(1→2)-α-L-arabinopyranoside 基于光谱分析和化学证据。
