摘要
目的研究白斑枪刀药Hypoestes phyllostachya地上部分的化学成分。方法采用硅胶柱色谱、MCI、HPLC等色谱技术进行分离纯化,根据波谱技术进行化合物结构鉴定。结果从白斑枪刀药地上部分95%乙醇提取物中分离得到18个化合物,分别鉴定为(3R,6R,7E)-3-羟基-大柱烷-4,7-二烯-9-酮(1)、(3S)-3-羟基-β-紫罗兰酮(2)、(3S,5R,6S,7E)-3-羟基-5,6-环氧-大柱烷-7-烯-9-酮(3)、蚱蜢酮(4)、vomifoliol(5)、(+)-dehydrovomifoliol(6)、黑麦草内酯(7)、2,6-二甲基-2E,7-辛二烯-1,6-二醇(8)、bifurcanol(9)、(12S)-hydroxygeranylgeraniol(10)、nectandrin B(11)、N-反式阿魏酰酪氨(12)、丁香乙酮(13)、丹皮酚(14)、香草醛(15)、脱氢姜酮(16)、邻羟基苄醇(17)、(2E)-4-羟基-2-己烯酸(18)。结论所有化合物均为首次从该植物中分离得到。
Objective To study the chemical constituents from the aerial parts of Hypoestes phyllostachya. Methods The compounds were isolated and purified by silica gel column chromatography, MCI, and HPLC. Their structures were elucidated by spectroscopic analysis. Results Eighteen compounds were isolated from 95% ethanol aqueous extract of H. phyllostachya and the structures were identified as(3 R,6 R,7 E)-3-hydroxy-megastigma-4,7-dien-9-one(1),(3 S)-3-hydroxy-β-ionone(2),(3 S,5 R,6 S,7 E)-5,6-epoxy-3-hydroxy-megastigma-7-en-9-one(3), grasshopper ketone(4), vomifoliol(5),(+)-dehydrovomifoliol(6), loliolide(7), 2,6-dimethyl-2 E,7-octadien-1,6-diol(8), bifurcanol(9),(12 S)-hydroxygeranylgeraniol(10), nectandrin B(11), N-trans-feruloyltyramine(12), syringylethanone(13), paeonol(14), vanillin(15), dehydrozingerone(16), 2-hydroxybenzyl alcohol(17), and(2 E)-4-hydroxy-2-hexenoic acid(18). Conclusion All compounds are isolated from this plant for the first time.
