Dendrobium Sw., a member of the family Orchidaceae, includes approximately 1100 species distributed in different parts of the world. In China, the genus is represented by 76 species and two varieties, of which D. loddigesii, D. fimbriatum, D. chrysanthum, D. officinale (=D. candidum) and D. nobile are listed in the Chinese Pharmacopoeia as the source material for Herba Dendrobii (Shihu). Because of increased demand and high price, Herba Dendrobii is often adulterated in the trade by other related species. Many Dendrobium species are over-collected from the wild and are listed under endangered taxa in the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Therefore, a reliable authentication method is needed to regulate the trade and help conserve the species from unscrupulous collections. This review describes the present status of using medicinal Dendrobium in China, current approaches to authenticate medicinal Dendrobium plants and Herba Dendrobii, and the efforts under way towards the development of DNA microarrays to facilitate differentiation/identification of genuine material in complex Chinese medicinal formulations.
