摘要
从沙打旺分离到15个化合物,经光谱分析,理化实验及与已知化合物比较,鉴定了11个化合物,其中两个为四环三萜类化合物,分别鉴定为(20R,24S)-3.16-二羰基-6α,25-二羟基-20,24-环氧-9.19-环羊甾酮(9)和(20R,24S)-3,16-二羰基-6α,25-二羟基-20,24-环氧-9,19-环-23氧-羊毛甾酮(10)。
Fifteen comounds have been isolated from Astragalus adsurgens Pall. Structures of eleven compounds were identified by means of spectral and chemical methods and compared with known compounds. Among all the compounds, 9 and 10 are new triterpene compounds, their structures have been elucidated as follows: (20R, 24S)-3, 16- dicorb-onyl -6 α, 25-dihydroxy-20, 24-epoxy-9,19-cyclpadsurgenin, (20R, 24S)-3,16-dicorbo-nyl -6α,25-dihydroxy-20, 24-epoxy-23-nitrogen-9, 19-cycloadsurgenin.
