MicroHLPC determination of amygdalin in Semen pruni armeniacae and Semen pruni persicae.
The application of micro HPLC to the determination of amygdalin in Semen pruni armeniacae and Semen pruni persicae is described. Amygdalin is separated at ambient temperature on a reversed phase column of U-Finepak SIL C18(150 x 0.5 mm) with methanol + water (25:75 v/v) as the mobile phase at a flow rate of 10 microL/min. The results are calculated by the internal standard method. The linear range is 1-7 micrograms. The CV and recovery of pure amygdalin are 1.47% (n = 10) and 98.13%, respectively. The results of analysis are lower than those obtained by TLC, but microHPLC is much simpler, faster, and more sensitive and reproducible than TLC.
