  • Title: [Applying grading methods of synthesizing multiple guidelines to optimizing extracting technology for Radix Panacis Quinquefolii].
    Author: Lei X, Shu J, Zhao C.
    Journal: Zhong Yao Cai; 2005 Jul; 28(7):599-601. PubMed ID: 16252731.
    Abstract:
    OBJECTIVE: To optimize the best extracting procedure for Radix Panacis Quinquefolii. METHODS: (1) The optimum alcohol extracting procedure was selected with the content and extraction efficiency of ginsenoside Rg, Re, Rb, from Radix Panacis Quinquefolii by orthogonal test design and synthesizing multiple guidelines method. (2) The content of three ginsenoides Rg1, Re and Rb1 in Radix Panacis Quinquefolii was determined by gradient elution method in RP-HPLC. RESULTS: The optimum alcohol-extracting procedure was determined as 12 times of 70% alcohol refluxing and extracting 3 h for 2 times. CONCLUSIONS: The optimum extracting procedure can increase extraction efficiency of Radix Panacis Quinquefolii.
