[Two kaempferol triglycosides from pericarps of Sophora japonica L].
OBJECTIVE
To study the flavonol triglycosides in the pericarps of Sophora japonica.


METHODS
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.


CONCLUSIONS
Both of them were reported in S. japonica for the first time.
