Sodium chimaerol sulfate (1) was isolated from the bile of Lamna ditropis and Rhizoprionodon acutus by chromatography on silica gel and Sephadex LH-20, together with sodium scymnol sulfates, (24R,25S)- and (24R,25R)-(+)-3 alpha,7 alpha,12 alpha,24,26-pentahydroxy-5 beta-cholestan-27-yl sodium sulfates (3 and 4) and 3, respectively. On acid hydrolysis, compound 1 afforded chimaerol (2), which was identified
在
硅胶和Sephadex LH-20色谱上通过色谱法从白生蛇舌草和Rh实胆的胆汁中分离出奇异麦角
酚硫酸钠(1),以及偏苯三
酚硫酸钠(24R,25S)-和(24R,25R)-(+) -3α,7α,12α,24,26-五羟基-5β-胆甾烷-27-基
硫酸钠(3和4)和3。酸
水解后,化合物1提供了Chimaerol(2),可通过直接比较将其鉴定为(24R,25R)-(+)-5β-胆甾烷-3α,7α,12α,24,26-
戊醇通过用LiAlH4还原(24R,25S)-(+)-24,26-环氧-5β-
胆固醇3α,7α,12α,27-四醇(5)制备的真实样品。根据
化学转化和光谱数据,得出1的结构为(24R,25R)-(+)-3α,7α,12α,24-四羟基-5β-
胆甾醇-26-基
硫酸钠。
