title: Studies on the molecular markers of rhizomes of some Alpinia species.
abstract: The rhizomes of Alpinia jianganfeng are used as a traditional Chinese medicine, Jian Gan Feng, to cure rheumatism in Guangdong, China. The rhizomes of some other species of the genus Alpinia such as A. japonica, A. suishaensis and A. nanchuanensis are also used as Jian Gan Feng in Southwest China. However, the identification of the original plants of the crude drugs is difficult. The internal transcribed spacers and the 5.8S coding region of nuclear ribosomal DNA of the four species were sequenced and analyzed. The DNA markers have been determined and they can be used for the molecular identification of these medicinal plants.
