Application of microscopic spectroscopy in quality control of Gejie Dingchuan pills
Application of microscopic spectroscopy in quality control of Gejie Dingchuan pills was discussed.Using the method of microscopic identification,the microscopic characteristics specified in the execution standards of Gejie Dingchuan pills was studied,and microscopic identification methods for other 8 medicinal herbs in the prescription unspecified inspection items was established.Simultaneously microscopic spectroscopy was used for test of Radix Ophiopogonis adulterant Radix Liriopes.Eight medicinal herbs,including Semen Trichosanthis,Radix Asteris,vinegar Carapax Trionycis,Radix Glycyrrhizae,Radix Ophiopogonis,roasted Fructus Perillae,roasted Semen Armeniacae Amarum and Gypsum Fibrosum were selected for their powder microscopic characteristics with high microscopic inspection rates,serving as the basis for microscopic identification of Gejie Dingchuan pills.The microscopic identification characteristics of Radix Ophiopogonis and Radix Liriopes in traditional Chinese patent medicines and simple preparations were studied and established for the first time;corresponding microscopic features could be detected in all 12 batches of samples,but no microscopic features of Radix Liriopes were detected,there was no significant difference in sample quality in the microscopic identification.The proposed methods were simple,rapid,objective and economic,which offered a more comprehensive approach for quality control of Gejie Dingchuan pills.It is indicated that conventional technology such as microscopic spectroscopy can play an important role in identification of traditional Chinese medicine whose index ingredient is deficient or tiny.
