analysis of ampelopsis megalophylla diels et. gilg by hplc fingerprint shen wei, chen shuhe,zhang xiuqiao,liu yanwen 1.hubei college of traditional chinese medicine,wuhan 430065,china; 2. affiliated hospital of hubei college of traditional chinese medicine,wuhan 430061,china abstract:objective to establish an hplc fingerprints of the effective part of ampelopsis megalophylla diels et. gilg for reflecting the internal chemical information and evaluating its quality in a scientific and effective way. methodshplc method was applied for the quality assessment of ampelopsis megalophylla diels et. gilg.the preparation of sample,the hplc column,mobile phase,elution mode(isocratic and gradient) and gradient program were optimized in order to obtain high qualified hplc profile.the hplc system consisted of a waters 600e pump and a 2996 photodiode-array detector(dad).data were acquired and processed with the empower workstation.hplc analysis was performed on an agilent tc c18 column (250 mm×4.6 mm,5 μm) with the mixture of acetonitrile and 0.1% phosphoric acid aqueous solution as the mobile phase in gradient mode.the column temperature was set at 30℃,the flow rate was 1.0 ml/min,and the detection wavelength was at 250 nm. resultsthe hplc fingerprints of the effective part of ampelopsis megalophylla diels et. gilg showed 10 common peaks in 10 batches of samples collected at different time. by comparison of the retention time and the on-line uv spectra of chemical standards,peak1,5,6,9 and 10 were identified as ampelosin, taxifolin, quercitrin, quercetin and myricetin, respectively.conclusionthe hplc fingerprint of the effective part of ampelopsis. megalophylla diels et. gilg with high specificity can be used to control its quality. key words: ampelopsis megalophylla; effective part; hplc fingerprint; taxifolin staherb
