Four new dihydrostilbenes, alpha,alpha'-dihydro-3,5-dihydroxy-4'-acetoxy-5'-isopentenylstilbene (1), alpha,alpha'-dihydro-3,3',4'-trihydroxy-5-O-isopentenyl-6-isopentenylstilbene (2), alpha,alpha'-dihydro-3,5,3'-trihydroxy-4'-methoxystilbene (3), and alpha,alpha'-dihydro-3,3'-dihydroxy-5beta-d-O-glucopyranosyloxy-4'-methoxystilbene (4), together with seven known flavonoids, glabranin isomer, naringenin, lupiwighteone, pinocembrin 7-O-glucoside, astragalin, isoquercitrin, vicenin II, and the inositol, pinitol, were isolated from the leaves of Glycyrrhiza glabra grown in Sicily. The structures of 1-4 were elucidated by spectroscopic methods.
从生长在西西里岛的光果甘草叶中分离出4种新的二氢茋类化合物，即α,α'-二氢-3,5-二羟基-4'-乙酰氧基-5'-异戊烯基茋（1）、α,α'-二氢-3,3',4'-三羟基-5-O-异戊烯基-6-异戊烯基茋（2）、α,α'-二氢-3,5,3'-三羟基-4'-甲氧基茋（3）和α,α'-二氢-3,3'-二羟基-5β-d-O-吡喃葡萄糖氧基-4'-甲氧基茋（4），以及7种已知的黄酮类化合物，即光甘草定异构体、柚皮素、羽扇豆黄烷酮紫檀素、松属素7-O-葡萄糖苷、紫云英苷、异槲皮苷、异荭草苷II，还有肌醇、松醇。通过光谱方法阐明了1-4的结构。
