  摘要：

  通过将已知皂苷 momordin I 与 betavulgaroside II 和 IV 进行化学关联，确定了从甜菜（藜科）根部分离出的具有对葡萄糖负荷大鼠的降血糖活性的含有二氧六环型取代基的 betavulgaroside II 和含有缩酮型取代基的 betavulgaroside IV 的绝对立体结构。在这些化学关联中，momordin I 的 α-L-阿拉伯糖苷部分被转化为 betavulgaroside II 的二氧六环型取代基或 betavulgaroside IV 的缩酮型取代基。此外，从 momordin I 合成了 betavulgaroside IV 的 2'-非对映异构体，并从 L- 和 D-阿拉伯糖合成了四种缩酮型取代基类似物。

  摘要：

  Five glucuronide saponins named betavulgarosides I, II, III, IV, and V were isolated from the roots and leaves of Beta vulgaris L. (Sugar beet). Their structures were elucidated on the basis of chemical and physicochemical evidence. Betavulgarosides II, III, and IV and the prosapogenol (6) were found to exhibit hypoglycemic effect on oral glucose tolerance test in rats.

  The absolute stereostructures of betavulgaroside II having a dioxolane-type substituent and betavulgaroside IV having an acetal-type substituent, which were isolated from the roots of Beta vulgaris L. (sugar beet, Chenopodiaceae) and exhibited hypoglycemic activity on glucose-loaded rats, were determined by the chemical correlations of betavulgarosides II and IV with a known saponin, momordin I. In these chemical correlations, the α-L-arabinopyranosyl moiety of momordin I was converted to a dioxolane-type substituent of betavulgaroside II or to an acetal-type substituent of betavulgaroside IV. Additionally, the 2'-diastereoisomer of betavulgaroside IV was synthesized from momordin I, and four acetal-type substituent analogues were also synthesized from L- and D-arabinose.
