白薇化学成分及其抗烟草花叶病毒活性研究
前期研究发现seco-pregnane类甾体苷具有较强的抗烟草花叶病毒(TMV)活性,为进一步寻找活性化学成分,开展白薇化学成分研究.从白薇乙醇提取物的氯仿部位中分离得到10个单体化合物,根据其理化性质以及波谱数据鉴定为:glaucogenin-C 3-O-α-L-diginopyranosyl-(1→4)-β-D-thevetopyranoside(1)、glaucogenin-C 3-O-β-D-oleandropyranosyl-(1→4)-β-D-digitoxopyranosyl-(1 →4)-α-L-cymaropyranoside(2)、glaucogenin-C 3-O-β-D-glucopyranosyl-(1→4)-β-D-glucopyranosyl-(1→4)-β-D-oleandropyranoside(3)、glaucogenin-A 3-O-α-L-cymaropyranosyl-(1 →4)-β-D-digitoxopyranosyl-(1→4)-β-D-oleandropyranoside (4) 、glaucogenin-A 3-O-α-L-diginopyranosyl-(1→4)-β-D-cymaropyranosyl-(1→4)-β-D-oleandropyranoside (5)、glaucogenin-A 3-O-α-L-cymaropyranosyl-(1 →4)-α-L-cymaropyranosyl-(1 →4)-β-D-oleandropyranoside(6)、glaucogenin-A 3-O-α-L-cymaropyranosyl-(1 →4)-β-L-cymaropyranosyl-(1→4)-β-L-cymaropyranoside (7)、 glaucogenin-A 3-O-α-L-cymaropyranosyl-(1→4)-β-D-cymaropyranosyl-(1→4)-β-L-cymaropyranoside(8)、antofine (9) 、2-O-β-D-fructofuranosyl-β-D-glucopyranoside (10).化合物1~8,10均为首次从该植物中分离得到.采用半叶枯斑法,从钝化活性、保护活性、治疗活性三方面评估化合物1~9的生物活性,结果表明,化合物1和9具有显著的抗TMV活性.
