Use of X-ray Diffractometry for Identification of Different Fritillaria Traditional Chinese Medicine

Wang Shujun, Yu Jinglin and Gao Wenyuan

Abstract:
Comparative studies of different Fritillaria Chinese medicinal materials were carried out using X-ray powder diffraction. Due to existence of plenty of starches in Fritillaria, which is a very good semicrystalline macromolecule, the X-ray diffraction pattern of Fritillaria powders mainly showed the crystal properties of starch. However, the crystal properties of starch contained in Fritillaria were highly different due to the differences of species. These differences in crystal properties of starch resulted in the differences in the diffraction pattern. In addition, the differences in other chemical constituents contained in Fritillaria also resulted in the differences in the diffraction patterns. All of these differences could be utilized for the discrimination and identification of different Fritillaria Traditional Chinese Medicine. In the present research, we conducted a systematic study on eight kinds of Fritillaria traditional Chinese medicines by X-ray power diffraction. X-ray diffraction is proved to be a new and powerful method to discriminate Fritillaria traditional Chinese medicines from different geographical origins.
