Authentication of Acori Tatarinowii Rhizoma (Shi Chang Pu) and its adulterants by morphological distinction, chemical composition and ITS sequencing.

ABSTRACT:

Background

Acori Tatarinowii Rhizoma (ATR; rhizome of Acorus tatarinowii Schott) (Shi Chang Pu) is widely used in Chinese medicine (CM) to resuscitate, calm the mind, resolve shi (dampness) and harmonize the wei (stomach). Seven different species have been identified as belonging to the genus Acorus, all of which can be found in China. However, it can be difficult to distinguish the different species of Acorus because of their morphological similarities. The aim of this study was to authenticate Acorus species using macroscopic and microscopic techniques, chemical analysis and DNA authentication and to compare the resolution power and reliability of these different methods.

Methods

Four batches of ATR, Acori Gram
