Discussion on Use of Pinelliae Rhizoma Processed Products in Famous Classical Formulas / 中国实验方剂学杂志

There are 17 formulas containing Pinelliae Rhizoma in the Catalogue of Ancient Famous Classical Formulas (the First Batch), most of which are only labeled with " washing with decoction" or without any processing method, which is inconsistent with the current use requirements and brings confusion to research and development of related famous classical formulas. Through combing the records of famous classical formulas in the original book, contemporary works and later works, the usage of processed products of Pinelliae Rhizoma in the evolution of past dynasties was contrasted, and the efficacy, indications and compatibility significance of different formulas were analyzed, according to the principle of " respecting the ancient but not confining the ancient" , the authors suggested that the 17 famous classical formulas should use the processed products of Pinelliae Rhizoma in the 2015 edition of Chinese Pharmacopoeia, including Pinelliae Rhizoma Praeparatum, Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine and Pinelliae Rhizoma Praeparatum cum Alumine. Among them, Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine should be used in Banxia Xiexintang, Gancao Xiexintang, Huangliantang, Xuanfu Daizhe Tang, Zhuye Shigaotang, Banxia Houpotang, Maimendong Tang, Gualou Xiebai Banxiatang, Wendantang, Zhurutang, Jinshui Liujun Jian and Yangweitang, Pinelliae Rhizoma Praeparatum should be used in Shengyang Yiweitang, Houpo Mahuangtang, Banxia Baizhu Tianma Tang and Huopo Xialing Tang, and Pinelliae Rhizoma Praeparatum cum Alumine should be used in Sangbaipi Tang.

Textual Research on Processing Methods of Pinelliae Rhizoma in Successive Dynasties / 中国实验方剂学杂志

This paper discussed the processing methods of Pinelliae Rhizoma in the successive dynasties by consulting ancient and modern books, literature and related codes. The processing methods of Pinelliae Rhizoma has experienced various historical periods. Since the processing method of Pinelliae Rhizoma processed by slicing appeared in the Huangdi Neijing, there have been a series of different processing methods and requirements are founded, such as cleansing, cutting, decocting and so on. Among them, the raw Pinelliae Rhizoma, Pinelliae Rhizoma Praeparatum, Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine, Pinelliae Rhizoma Praeparatum cum Alumine are still in use today and are widely used. However, there are differences in the processing methods, accessories and their dosages of these various processed products in different dynasty. The processing technology and quality standard of Pinelliae Rhizoma need to be further standardization.

Study on processing of origin integration method and technology of Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine / 中草药

Objective: To evaluate and optimize the origin integration method and process of Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine (PRPZA). Methods: Taking the content of calcium oxalate crystal as an index to screen the way of adding ginger and heating method, taking the content of calcium oxalate crystal, the content of water-soluble extracts, and amount of alum residue as the indexes, with the method of orthogonal design and the comprehensive scoring to optimize the processing technology of fresh Pinelliae Rhizoma. Results: The optimized processing method and technology was for per 100 g fresh Pinelliae Rhizoma, plus alum 10 g, mashed ginger 20 g, the common heating to boil after 30 min, soaking for 3 d, and then to 120 ℃ pressure cooking 40 min, rinsing to semi dry, being sliced and dried. Conclusion: The selected origin integration method and technology could not only reduces the content irritant toxic components of calcium oxalate crystal, also avoids the losses of active ingredients, and improve the quality of decoction pieces.
