[Studies on the flavonol glycosides from the seeds of Vaccaria segetalis].

OBJECTIVE
To study the chemical constituents of the seeds of Vaccaria segetalis.


METHOD
Chromatography and spectral analysis were used to isolate the constituents and elucidate their structure.


RESULT
Three compounds were isolated from alcohol extract of the seeds of V. segetalis, and identified as apigenin-6-C-arabinosylglucoside(1), apigenin-6-C-glucosylglucoside(2), vaccarin(3).


CONCLUSION
Compound 1 and 2 were isolated from the seeds of this plant for the first time.
