The structure of a new triterpenoid saponin, frondoside D, isolated from Cucumaria frondosa has been determined principally by high field 1D and 2D NMR and FAB-MS spectrometry. Frondoside D was shown to be 3 beta-[3-O-methyl-O-beta-D-glucopyranosyl-(1-3)-O-beta-D- xylopyranosyl-(1-4)-[O-beta-D-xylopyranosyl-(1-2)]-O-beta-D- quinovopyranosyl-(1-2)-O-beta-D-4-sulfonatoxylo-pyranosyl]-1 6 beta-acetoxy-23S-hydroxy-holost-7-ene, sodium salt.
从海黄瓜（Cucumaria frondosa）中分离出的一种新的三萜皂苷——叶苷D的结构，主要通过高场一维和二维核磁共振以及快原子轰击质谱法确定。叶苷D被证明是3β-[3-O-甲基-O-β-D-吡喃葡萄糖基-(1→3)-O-β-D-吡喃木糖基-(1→4)-[O-β-D-吡喃木糖基-(1→2)]-O-β-D-奎诺吡喃糖基-(1→2)-O-β-D-4-磺基氧基吡喃木糖基]-16β-乙酰氧基-23S-羟基-海参甾-7-烯钠盐。
