[Determination of alpha-cyperone in Rhizoma Cyperi oil by HPLC].

Abstract

OBJECTIVE To establish a method deteminating alpha-cyperone in Rhizome Cyperi oil by HPLC. METHODS The determination was carried out by Merck Lichrocart C18 column, with mobile phase consisted of methanol-water (68: 32), and detective wavelength 241 nm. RESULTS The calibration curves was linear in the range of 0. 081 - 0. 81 microg/ml (r = 0.9998). The… (More)
