从十字花科植物桂竹香糖芥(Erysimumcheiranthoides)的种子中分离得到3个新的强心苷类化合物。 取桂竹香糖芥种子(2.5kg)用甲醇提取,甲醇提取物在正己烷和水中分配,水层(123g)上MCI gelCHP 20P柱层析,依次用40％、60％、80％、100％甲 Three new cardiac glycoside compounds were isolated from the seeds of the cruciferous plant Erysimum cheiranthoides. The cinnamon mustard seeds (2.5kg) were extracted with methanol, and the methanol extract was partitioned with n-hexane and water. The water layer (123g) was chromatographed on a MCI gelCHP 20P column, followed by 40%, 60%, 80%, and 100%, respectively. A
