目的 研究檵木水溶性化学成分。方法 采用大孔树脂、硅胶、凝胶、制备高效液相等色谱技术进行分离,根据波谱数据对化合物进行结构鉴定。结果 从檵木叶中分离得到10个化合物,分别鉴定为(6S,9R)-roseoside(1),rhododendrin(2),epirhododendrin(3),(1S,2R,4S,5S)(-)-Angelicoidenol 2-O-β-D-glucopyranoside(4),dihydroalangionoside A(5),(Z)-3-hexenyl β-primeveroside(6),benzyl β-primeveroside(7),(Z)-3-hexenyl O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside(8),rhododendrol 4'-O-β-D-glucopyranoside(9),3-(4-hydroxyphenol)propyl β-D-glucopyranoside(10)。结论 化合物1~7,9,10均首次从该属植物中分离得到。
Abstract
OBJECTIVE To study the water-soluble chemical constituents in the leaves of Loropetalum chinense. METHODS The chemical constituents were isolated by macroporous resin, ODS column, silica gel column, Sephadex LH-20 and preparative HPLC. Their structures were identified on the basis of spectral data analysis. RESULTS Ten compounds were isolated from L.chinense leaves and identified as(6S,9R)-roseoside(1), rhododendrin(2), epirhododendrin(3), (1S,2R,4S,5S)(-)-angelicoidenol 2-O-β-D-glucopyranoside(4), dihydroalangionoside A(5),(Z)-3-hexenyl β-primeveroside(6), benzyl β-primeveroside(7),(Z)-3-hexenyl O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside(8), rhododendrol 4'-O-β-D-glucopyranoside(9), and 3-(4-hydroxyphenol)propyl β-D-glucopyranoside(10). CONCLUSION Compounds 1-7, 9, and 10 are isolated from this genus for the first time.
