[Study on Glycosides Constituents from Guangdong Liangcha Granules(II)]
Objective:
To study the glycosides from Guangdong Liangcha Granules.
Methods:
The chemical constituents were isolated by various chromatographic techniques and the structures of chemical constituents were identified by spectroscopic analysis and literature.
Results:
Six compounds were isolated and identified as ilexoside B (1), asprellanosides B (2), asprellanoside A (3), 4', 5 ,7 -tri- hydroxyflavone-6-O-β3-D-glucopyranosyl ester(4), isoviolanthin (5),3-O-methy-lellagic acid 4'-O-rhamnopyranoside (6).
Conclusion:
Compounds 1 - 5 are firstly obtained from Guangdong Liangcha Granules.
