| 摘 要： | A number of constituents were isolated from the root of Actinidia chinensis Planch. Seven of them were indentified as physcion (emodin-6-methyl ether) (T1), emodin (frangala-emodin) (T2), emodin-8-β-D-glucoside (T3), questin (emodin-8-methyl ether) (T5), citreorosein (ω-hydroxyemodin) (T6), emodic acid (T7) and β-sitosterol (T4).Comparison of the 1HNMR data of emodin (T2) and its 8-glucoside (T3) shows that the aromatic proton experiences a downfield shift of about 0.5 ppm upon glycosidation of an ortho phenolic group, a fact which can be used to advantage for the allocation of the glycosidic linkage.
