Abstract:
AIMTo establish an HPLC-ELSD method for the simultaneous determination of five major bioactive isosteroidal alkaloids and gluco-alkaloids in the bulbs of Fritillaria namely peimissine, imperialine, sinpeinine A, imperialine-3 beta-glucoside and yibeinoside A.
METHODSA Nova-Pak C18 column (150 mm x 3.9 mm ID) was used. The chromatography was carried out with a linear gradient programming. The mobile phase was acetonitrile-water (containing 0.1% diethylamine) and the flow rate was 1.0 mL.min-1.
RESULTSThe linear range of peimissine was 13.1-288.2 mg.L-1 (r2 = 0.9975), imperialine-3 beta-glucoside 7.7-169.4 mg.L-1 (r2 = 0.9993), yibeinoside A 7.3-160.6 mg.L-1 (r2 = 0.9997), imperialine 16.5-363.0 mg.L-1 (r2 = 0.9992), sinpeinine A 8.7-191.4 mg.L-1 (r2 = 0.9942).
CONCLUSIONThe method is accurate with overall intra- and inter-day variation less than 5% and recovery more than 95%. The method was successfully applied to analyze five major bioactive alkaloids and gluco-alkaloids in three Fritillaria bulbs.
