  • Objective To compare the changes of four flavonoid glycosides in the leaves of Hippophae rhamnoides L. before and after fermentation. Methods The water extract of Hippophae rhamnoides L. leaves and its fermented tea were concentrated and desiccated. The dry extracts were dissolved in 70% ethanol. The chromatographic separation was performed with RP-HPLC method on an Extend-C18 column (4.6 mm×250 mm, 5 μm). Acetonitrile-0.1% formic acid was selected as mobile phase at the flow rate of 1.0 ml/min. The detection wavelength was 356 nm and the column temperature was 30℃. Results The rutin content was high in the leaves of Hippophae rhamnoides L. After fermentation, isoquercitrin content was increased, while the contents of rutin and narcissoside were reduced and isorhamnetin-3-O-glucoside stayed unchanged. There was a good linear relationship between the concentration and peak areas of the four compounds (r>0.9997). The average recoveries were between 96%-103%. Conclusion This established method is rapid and reliable, which can be used for the quality control of Hippophae rhamnoides L. leaves and its fermented tea.
