Analysis on X-ray Diffraction Fourier Fingerprint Pattern of RHIZOMA PINELLIAE

摘要： [Objective] To develop a new identification and analytical method for RHIZOMA PINELLIAE. [Method] X-ray diffraction Fourier fingerprint pattern was adopted to obtain the micro-diffraction pattern and characteristic marked peaks of RHIZOMA PINELLIAE, based on which the identification of different samples, the difference between the original and processed RHIZOMA PINELLIAE products as well as the difference in the content of related components were analyzed, so as to realize the micro identification and analysis of common herbal medicines. [Result] According to their micro-diffraction patterns and characteristic marked peaks, 12 RHIZOMA PINELLIAE and their processed products could be divided into five groups of medicinal RHIZOMA PINELLIAE, RHIZOMA TYPHONII FLAGELLIFORMIS, and their processed products of RHIZOMA PINELLIAE PRAEPARATUM, RHIZOMA PINELLIAE PRAEPARATUM CUM ZINGIBERE ET ALUMINE and RHIZOMA PINELLIAE PRAEPARATUM CUM ALUMINE. The standardization of herbal medicinal quality was extended from the microscopic qualitative identification of macro traits to the repeatable micro information characterized by images and data. [Conclusion] The method of X-ray diffraction Fourier fingerprint pattern could be used for the identification of RHIZOMA PINELLIAE. ... （共4页）
