茄科栽培植物食用酸浆(Physalis ixocarpa Brot.)的已知价值在于其果实。作者在本文中报导了其叶中含有的三种成份的分离和结构研究的结果。取阴干叶子,用甲醇渗漉,渗漉液浓缩后稍加水稀释,即用正已烷振摇除去有色和脂性杂质,然后用大量乙醚提取。提取物转溶入氯仿,在氧化铝柱上依次用石油醚、苯、氯仿洗脱,最后以2.5%甲醇的氯仿液洗脱。薄层层析分离后合并相同组份。在苯和苯-氯仿(9∶1)的洗脱液中分离得Pi-1;氯仿洗脱液中分离得Pi-2;2.5%甲醇的氯仿液中分离得Pi-3。 Pi-1为微粒结晶,分子式C_(28)H_(40)O_7,熔点245～250°(甲醇),λ_(max)(甲醇)220毫微米
The well-known value of solanaceous Physalis ixocarpa Brot. Lies in its fruit. The authors report the results of the separation and structure studies of the three components contained in their leaves. Take dried leaves, with methanol percolation, percolate concentration after a little water dilution, that is, n-hexane shake to remove colored and fat impurities, and then with a large number of ether extraction. The extract was transferred into chloroform and eluted with petroleum ether, benzene and chloroform on an alumina column and finally eluted with 2.5% methanol in chloroform. The same components are combined after thin layer chromatography. Pi-1 was isolated from the eluent of benzene and benzene-chloroform (9: 1); Pi-2 was separated from the chloroform eluate; and Pi-3 was isolated from the chloroform solution of 2.5% methanol. Pi-1 is a crystalline particle with the molecular formula of C_ (28) H_ (40) O_7, melting point 245-250 ° (methanol), λ max (methanol) 220 nm
