英文摘要
A counterfeit Cordyceps (Dongchong Xiacao) was found retailed in certain high-class health food stores in Hong Kong and is expected to he found also in Taiwan and overseas since Hong Kong is a major entrepot of Chinese medicines. A combination of morphological and anatomical studies of the counterfeit and genuine samples of Cordyceps as well as fresh materials of the rhizome and stem of Stachys geobombycis C.Y. Wu (Labiatae) was conducted. The latter herb is known as Guangdong Chongcao in southern China. The results led to the conclusion that the 'larval body' of the counterfeit was derived from the underground rhizome of S.geohombycis by drying and subsequent rolling into a rod-shaped structure of somewhat uniform diameter and coated with a yellow pigment or powder. The 'fungal portion' of the counterfeit attached to one end of the 'larval body' was derived from a segment of the stein of the same plant, which was cooked and blackened, to imitate the fungal portion of genuine Cordyceps. Soaking the counterfeit in water would cause the yellow coating to precipitate off the 'larval body' and revive the dried rhizome to its original form which is whitish and bearing distinct circular nodes and lateral buds. Cross-sections of the 'larval body' and 'fungal portion' of the counterfeit also revealed anatomical profiles characteristic of the rhizome and stem of S.geobombycis, respectively. Photographs of the herbs and micrographs of the cross-sections are presented to facilitate identification.
