[Two kaempferol triglycosides from pericarps of Sophora japonica L]
1Department of Natural Pharmaceutical Chemistry, China Pharmaceutical University, Nanjing 210038, Jiangsu, China.
Objective:
To study the flavonol triglycosides in the pericarps of Sophora japonica.
Method:
Various chromatographic techniques were used to isolate and purify the constituents. The structures were elucidated by chemical evidence and spectral analysis, especially by 2D NMR experiments.
Results:
Two kaempferol triglycosides were isolated and identified as kaempferol 3-O-beta-D-sophoroside-7-O-alpha-L-rhamnoside and kaempferol 3-O-(2"-O-beta-D-glucosyl)-beta-D-rutinoside.
Conclusion:
Both of them were reported in S. japonica for the first time.
