[Study on original plant species and geographical distribution of Fructus Aurantii].

The original plant species of Fructus Aurantii are multitudinous and complex, and their requirements to the growing environment is strict. In order to clarify the original plant species and geographical distribution of Fructus Aurantii which recorded in the standards and circulated, used in commodity. The national and local standards of Chinese medicinal materials were collected and the original plants of Fructus Aurantii recoded in standards were found. Ten original plant species of Fructus Aurantii (including varieties of cultivars, the same below) were recorded in the Chinese pharmacopoeia and six local standards of Zhejiang, Yunnan and Guizhou etc. The producing areas and commodity in markets of Fructus Aurantii were investigated. The growth environment and geographical distribution of them were analyzed. There are six types of Fructus Aurantii i.e., Fructus Aurantii Chuan, Fructus Aurantii Xiang, Fructus Aurantii Jiang, Fructus Aurantii Qu, Fructus Aurantii Su, Fructus Aurantii Wen, and nineteen species of original plants in the practical commodities. There are four major Fructus Aurantii producing areas: Sichuan Basin, Dongting Lake Plain, Poyang Lake Plain, Jinqu Basin and its surrounding hilly areas. All of them are located in the area of the east longitude 104° to 121° and the northern latitudes 27° to 31°. There is a certain difference between the actual commodity and the standards of medicinal materials. It is suggested that the traditional mainstream types of Fructus Aurantii with fine quality should be accepted into Chinese Pharmacopoeia, and the types with poor quality should be withdrawn from Chinese Pharmacopoeia.
