Abstract��
OBJECTIVE To determine the content of peimisine in Fritillaria taipaiensis and Fritillaria unibracteata, the novel resource of fritillariae cirrhosae bulbus. METHODS A high performance liquid chromatography coupled with evaporative light scattering detector was employed, and peimisine was separated and quantified upon an Agilent Hypersil BDS-C18 column (4.0 mm��250 mm��5 ��m) using acetonitrile-water-diethylamine as the mobile phase in a gradient program at the flow rate of 1.0 mL��min-1. RESULTS Within the test range of 40.75-815.00 ��g��mL-1, the logarithm of peak area of peimisine versus the logarithm of nominal mass showed good correlation (r=0.999 4), and the mean recovery of analyte was 98.7% with RSD of 2.5% (n=6). The obtained content varied from 0.017 3% to 0.037 6% in Fritillaria taipaiensis and from 0.023 3% to 0.052 8% in Fritillaria unibracteata, respectively. CONCLUSIONFritillaria taipaiensis and Fritillaria unibracteata contained higher content of peimisine than fritillariae cirrhosae bulbus.
