Authentication of commercial processed Glehniae Radix (Beishashen) by DNA barcodes.

ABSTRACT:

Background

The radix of Glehnia littoralis Fr. Schmidt ex Miq. (Beishashen), is often misidentified and adultered in Chinese medicine. Its seven common adulterants include Chuanminshen violaceum Sheh et Shan (Chuanmingshen), Changium smyrnioides Wolff (Mingdangshen), Sphallerocarpus gracilis (Bess.) K.-Pol. (Miguoqin), Adenophora polyantha Nakai (Shishashen), Silene tatarinowii Regel (Shishengyingzicao), Adenophora tetraphylla (Thunb.) Fisch (Lunyeshashen) and Adenophora stricta Miq. (Shashen). This study aims to evaluate the feasibility of the second internal transcribed spacer (ITS2) DNA barcoding to discriminate between Glehniae Radix and its common adulterants.

Methods

In this study, we collected 46 samples of G. littoralis and 59 samples of its seven common adulterants.
