石椒为芸香科植物。其地上部分的50%正醇提取液呈解痉作用,并发现活性成份在己烷和氯仿可溶部分。本文进行了化学分离鉴定和药理活性的比较。干燥材料先后用己烷和氯仿提取。己烷提取物行硅胶柱层析,依次用苯～己烷(1:3,1:1)和苯洗脱。从不同比例的苯～己烷洗脱液分别得到3-(1,1-二甲基烯丙基)黄石亭(Xanthyletin)和廿八烷酸;从苯洗脱液
Pepper Rutaceae plants. The 50% of the above alcoholic extract of the aerial part showed antispasmodic activity and the active ingredient was found to be soluble in hexane and chloroform. In this paper, chemical isolation and identification and pharmacological activity comparison. The dried material was extracted with hexane and then with chloroform. The hexane extract was subjected to silica gel column chromatography, which was eluted with benzene-hexane (1: 3, 1: 1) followed by benzene. 3- (1,1-dimethylallyl) xanthyletin and octacosane were obtained from benzene-hexane eluents with different proportions respectively;
