从贵州老鹰茶Litseacoreana叶中分得 3个黄酮类化合物单体 ,经化学分析和波谱学方法确定了它们的化学结构 ,分别为山柰酚 ,山柰酚_3_O_β_D_葡萄糖苷和槲皮素_3_O_β_D_葡萄糖苷
Three flavonoid monomers were isolated from the leaves of Litseacoreana in Guizhou eagle tea. Their chemical structures were identified by chemical analysis and spectroscopy. They were kaempferol, kaempferol_3_O_β_D_glucoside and quercetin _ 3_O_β_D_ glucoside
