Detection of Ginsenoside CK Content in Ginsenoside Products and Their Products by HPLC
This article establishes a high-performance liquid chromatography (HPLC) method for detecting the content of ginsenoside CK in ginsenoside products and their derivatives. The linear regression equation of ginsenoside CK showed a good linear relationship,with a precision of 0.52% to 1.13% and a recovery rate of 94.9% to 104.3%,which meets the detection requirements.
