Abstract

Herba Dendrobii (Shihu) is a commonly used Chinese medicine derived from the stem of several orchid species belonging to the genus Dendrobium. it is rather expensive and adulteration is frequent. Proper authentication of themedicinal species is necessary to protect consumers and support conservation measures. DNA sequences of the internal transcribed spacer 2 (ITS 2) of 16 Dendrobium species were shown to be significantly different from one another by an average of 12.4% and from non-orchids and Pholidota (an adulterant of Shihu) by 29.8% and 18.8%, respectively, The intra-specific variationamong the Dendrobium species studied was only about 1%, Therefore, ITS Z regions could be adopted as a molecular marker for differentiating medicinalDendrobium species from one another and also from non-orchids and adulterants.
