摘要
从小金梅草乙醇提取物中分离得到了12个化合物,分别为3-O-β-D-槲皮素葡萄糖苷(1)、3-O-β-D-山柰酚葡萄糖苷(2)、5-O-β-D-芹菜素葡萄糖苷(3)、α-菠甾醇(4)、2,6-二甲氧基苯甲酸(5)、3-吲哚甲酸(6)、(2S,3R,4E,8E)-1-(β-D-吡喃葡萄糖苷)-N-[(R)-2'-羟基-二十碳酰基]-9-甲基-4,8-二烯-1,3-二醇-2-氨基-十八烷(7)、正三十二烷醇(8)、14,15-二十碳烯酸(9)、木腊酸(10)、β-谷甾醇(11)、胡萝卜苷(12)。以上化合物均为首次从该植物中得到。
Twelve compounds were isolated from the ethanol extract of Hypoxis aurea, and their structures were elucidated by physicochemical properties and spectroscopic analysis as quereetin-3-O-β-D-glucoside(1), kaemfeml-3-O-β-D-gluco- side (2), apigenin-5-O-β-D- glucopyranoside (3), α-spinasterol (4), 2,6-dimethoxy-benzoic acid (5), 1H-indole-3 -car- boxylic acid (6), ( 2S, 3R, 4E, 8E) -1- (β-D-glucopyranosyloxy) -3 -hydroxy-2 [ ( ( R ) -2'-hydmxyeicosanoly ) amino ] -9- methy-4,8 -octadecadiene (7), n-dotfiacontanol(8), 14,15 -eicosenicacid ( 9 ), lignoceric acid (10) β-sitoster-ol ( U ), daucosterol(12). All these compounds were found in this plant for the first time.
