Five new glycosides, which are classified into two bisdesmosidic pseudofurostanol glycosides (1, 2), two new ergostanol glycosides (3, 4), and a new phenolic glycoside (5), were isolated from the rhizomes of Tacca chantrieri. The structures of 1-5 were determined on the basis of extensive spectroscopic analysis, including that of two-dimensional (2D) NMR data, as well as hydrolytic cleavage followed by spectroscopic and chromatographic analyses.
从箭根薯的根茎中分离出了五种新的糖苷,它们被分为两种双糖苷键型假呋喃甾烷醇糖苷(1, 2)、两种新的麦角甾醇糖苷(3, 4)和一种新的酚糖苷(5)。1-5的结构是在广泛的光谱分析基础上确定的,包括二维(2D)核磁共振数据,以及水解裂解后进行的光谱和色谱分析。
