摘要
从丽江产黄瓜藤甲醇提取物的氯仿部位分离得到9个化合物,经理化和波谱分析鉴定为α-菠甾醇(1)、α-菠甾醇-3-O-β-D-葡萄糖苷(2)、β-谷甾醇(β-sitosterol,3)、豆甾-7-烯-3-O-β-D-葡萄糖苷(4)、22-亚甲基-9,19-环羊毛甾烷-3β-醇(5)、(2S,3S,4R,10E)-2-(2′,3′-二羟基二十四烷酰氨基)-10-十八烯-1,3,4-三醇(6)、(2S,3S,4R,10E)-2-[(2′R)-2-羟基二十四烷酰氨基]-10-十八烯-1,3,4-三醇(7)、(2S,3S,4R,10E)-1-(β-D-葡萄糖苷)-2-[(2′R)-2-羟基二十四烷酰氨基]-10-十八烯-1,3,4-三醇(8)、大豆脑苷(9),除化合物3外,其它化合物均为首次从该植物中分离得到。
Nine compounds were isolated from the chloroform fraction of the methanol extract of Cucumis sativus L. stems ,and their structures were elucidated by physicochemieal properties and spectroscopic analysis as α-spinasterol ( 1 ), α-spinasterol 3-O-β-D-glucopyranoside ( 2 ), β-sitosterol ( 3 ) , stigmast-7-en-3-O-β-D-glucopyranoside ( 4 ) , 22- methylene-9,19-cyclolanostan-3β-ol (5),(2S,3S,4R,lOE)-2-(2',3'-dihydroxytetracosanoylamino)-10-octadecene-1, 3,4-trlol ( 6 ) , ( 2S, 3S, 4R, 10E) -2- [ ( 2'R ) -2-hydroxy tetracosanoylamino ] -10-octadecene-1,3,4-triol ( 7 ), ( 2S, 3S, 4R, 10E ) -1 - (β-D-glucopyranosyl) -2- [ (2'R) -2 -hydroxytetracosanoylamino ] - 10 -octadecene- 1,3,4-triol ( 8 ), soya-cerebroside Ⅰ (9). By literature study, except for compound 3, the others were isolated from this plant for the first time.
