Objective: To investigate the influence of processing on contents of hypaphorine and flavonoid glycosides in Vaccariae Semen. Method: Before and after processing
HPLC was employed to determined contents and dissolution rates of hypaphorine
vaccarin
saponarin
isovitexin-2"-O-arabinoside and vaccarin H in Vaccariae Semen with the mobile phase of acetonitrile-water for gradient elution and detection wavelength at 280 nm. Result: Before processing
their contents were 0.13%
0.70%
0.018%
0.051%and 0.11%;after processing
their contents were 0.12%
0.52%
0.016%
0.098%and 0.091%
respectively.However
dissolution rates of these five ingredients were raised by 7.7%
10.2%
10.8%
11.4%and 17.8%
respectively. Conclusion: Processing has different influence on contents of hypaphorine and flavonoid glycosides in Vaccariae Semen
