目的研究犁头草(Viola japonica var.stenopetala Franch.ex H.)全草化学成分。方法运用多种色谱技术分离犁头草全草中活性成分,采用波谱技术和理化性质确定化合物的结构。结果从犁头草全草体积分数70%乙醇提取物中分离得到15个化合物,分别鉴定为β-谷甾醇(1)、胡萝卜苷(2)、绿原酸(3)、7-羟基香豆素(4)、豆甾醇-3-O-β-D-吡喃葡萄糖苷(5)、dehydrololiolide(6)、山柰酚-7-O-β-D-葡萄糖苷(7)、characterizedas(+)-pinoresinol-O-β-D-glucopyranoside(8)、5,7-二羟基-3,6-二甲氧基黄酮(9)、芹菜素-7-O-β-D-葡萄糖苷(10)、金圣草素(11)、β-香树素(12)、刺槐苷(13)、山柰酚-3,7-O-α-L-二鼠李糖苷(14)、solagenin-6-O-β-D-quinovopyranoside(15)。结论化合物8、15为首次从该属植物中得到,化学物5、6、8、11、14、15为首次从该植物中分离得到。
Objective To study the chemical constituents of the whole grass of Viola japonica var.stenopetala Franch. Methods A variety of chromatographic techniques were used to separate the active constituents from the whole plant grass. The structures of the compounds were determined by spectroscopic techniques and physico-chemical properties. Results Fifteen compounds were isolated from the 70% ethanol extract of P. gramineus and identified as β-sitosterol (1), daucosterol (2), chlorogenic acid (3), 7-hydroxycoumarin (4), stigmasterol-3-O-β-D-glucopyranoside (5), dehydrololiolide (6), kaempferol-7-O- ) -pinoresinol-O-β-D-glucopyranoside (8), 5,7-dihydroxy-3,6-dimethoxyflavone (9), apigenin-7-O-β-D-glucoside ), Kaempferol (11), β-amygdalin (12), locustin (13), kaempferol-3,7-O-α-L-rhamnoside (14), solagenin-6 -O-β-D-quinovopyranoside (15). Conclusions Compounds 8 and 15 were obtained from this genus for the first time. Chemicals 5, 6, 8, 11, 14 and 15 were isolated from this plant for the first time.
