Abstract
AIM To establish an HPLC method for the simuhaneous content determination of five flavonoids in Duchesnea indica (Andr.) Focke at five picking time (April,May,June,July and August).METHODS The analysis of D.indica methanol extract was performed on a 25 ℃ thermostatic Agilent ZORBAX SB-C18 column (250 mm×4.6 mm,5 μm),the mobile phase comprising of acetointrile-0.1％ methanoic acid flowing at 1.0 mL/min in a gradient elution manner,and the detection wavelength was set at 350 nm.RESULTS Rutin,hyperoside,isoquercitrin,celereoin and kaempferol showed good linear relationships within their own ranges (R2 ≥0.998 6),whose average recoveries were 97.1％-101.5％ with the RSDs of 1.37％-2.37％.The contents of five constituents in samples at different picking time exhibited obvious differences,among which lutin and hyperoside contents were the highest in June,isoquercitrin content was the highest in July,and celereoin and kaempferol contents were the highest in August.CONCLUSION The suitable picking time of D.indica is June and July.关键词
