摘要: 从中间锦鸡儿(Caragana intermediaK.)根部分离得到11种化合物成分, 分别为3-棕榈酰-β-谷甾醇(3-palmitoyl-β-sitosterol); 晁模酸(chaulmogricacid); 晁模酸乙酯(ethylchaulmoograte); 羽扇醇(lupeol); 胡罗卜甾醇(daucosterol); 三十一烷(hentriacontane); α-棕榈油酰甘油(α-palmitoleoylglycerol); α-棕榈酰甘油酯(α-palmitoyl-sn-glycerol); β-谷甾醇(β-sitosterol); 锦鸡儿甙-1(caraganoside-A)和锦鸡儿甙-2(caraganoside-B)。其中锦鸡儿甙-1和锦鸡儿甙-2为新天然产物。应用现代波谱技术(IR, UV, MS, 2DNMR)和化学降解方法确定了它们的化学结构。

Abstract: From the roots of Caragana intermedia K., two new triterpenoid glucosides, namely caraganoside A and caraganoside B, along with nine known compounds, 3-palmitoyl-β-si-tosterol, ethyl chaulmoograte, chaulmoogric acid, lupeol, daucosterol, hentriacontane, α-palmitoleoyl glycerol,α-palmitoyl-sn-glycerol, and β-sitosterol were isolated. Their structures were elucidated mainly by spectroscopic analysis.
