METHOD FOR DETERMINING ORIGIN OF GINSENG ROOTS AND LOTUS ROOTS USING RAPID RESOLUTION LIQUID CHROMATOGRAPHY-QUADRUPLE TIME OF FLIGHT MASS SPECTROMETRY(RRLC-QTOF/MS) AND A MULTIVARIATE STATISTICAL ANALYSIS METHOD

摘要

PURPOSE: A method for determining origin of ginseng roots and lotus roots is provided to resolve a wrong mark-of-origin problem and misconception in an oriental medicine market.;CONSTITUTION: A method for determining origin of ginseng roots and lotus roots comprises a step of isolating major ginsenoside compounds from each ginseng root sample by rapid resolution liquid chromatography-quadruple time of flight mass spectrometry(RRLC-QTOF/MS); and a step of analyzing with a multivariate statistical analysis method. The origin of the ginseng roots is Ganghwa and Punggi. The origin of the ginseng roots is determined as Ganghwa and Punggi based on the amount of ginsenoside Rf, ginsenoside Rg2, and notoginsenoside R2.;COPYRIGHT KIPO 2013
