Study on Water-Soluble Constituents from Tibetan Medicine Terminalia billirica (Gaert.) Roxb / 世界科学技术-中医药现代化

ABSTRACT

This paper aimed at investigating the water-soluble constituents of Terminalia billirica (Gaert.) Roxb.Compounds were isolated and purified by Diaion HP-20, Sephadex LH-20, Toyopearl HW-40, MCI gel CHP 20 P and ODS column chromatographies. The chemical structures were elucidated according to spectral data and physicochemical properties. The results showed that ten compounds were isolated and identified as corilagin, salicoside, methyl-α-Darabinofuranoside, 1, 4-dimethyl-β-d-fructopyranose, β-fructopyranose, β-fructofuranose gallic acid, ellagic acid, 1, 2, 3, 4, 6-penta-O-galloyl-β-D-glucopyranonside, Chebulagic acid. Except compound 7 and 8, others compounds are separated from Terminalia billirica (Gaert.) Roxb for the first time, and except corilgin, the other compounds are separated from Terminalia for the first time.
