从金银花Lonicerajaponica中又分得4个黄酮类化合物,分别鉴定为木犀草素-7-O-α-D-葡萄糖甙(luteolin-7-O-α-D-glucoside,Ⅰ),木犀草素-7-O-β-D-半乳糖甙(lute-olin-7-O-β-D-galactoside,Ⅱ),槲皮素-3-O-β-D-葡萄糖甙(quercetin-3-O-β-glu-coside,Ⅲ),金丝桃甙(hyperoside,Ⅳ),均为首次从金银花中获得.

Four flavonoids were isolated for the first time From Lonicera japonica Thunb..Their structures were identified by spectroscopic(IR, UV, ¹H¹³NMR,¹³CNMR and MS)and chemical methods as luteolin-7-O-α-D-glucoside(I),luteolin-7-O-β-D-galactoside(II),q-uercetin-3-O-β-D-glucoside(Ⅲ)and hyperoside(Ⅳ).
