摘要：

Two new cardenolide glycosides, one with a doubly-linked sugar, 15 beta-hydroxy-5,6-dehydrocalotropin and the other with a singly linked sugar, coroglaucigenin-3-(6-deoxy-beta-D-allopyranoside)-19-acetate, were isolated from the chloroform extract of the stems of Gomphocarpus sinaicus. Two other known cardenolides, were also isolated and identified as 5,6-dehydrocalotropagenin and 16 alpha-hydroxy-5,6-dehydrocalotropin. These compounds were isolated for the first time from G. sinaicus. Their identification was confirmed by 400 MHz H-1 and C-13 NMR, and EI mass spectral analysis.
