RESUMEN
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.
RESUMEN
Objective To establish a method for the determination of alum residual amount in Rhizoma Pinelliae Preparata from different companies,and to provide a scientific evidence for quality evaluation of Rhizoma Pinelliae Preparata.Methods Na2EDTA titration method was applied for the quantitative analysis.Results There were obvious differences in residual quantity of alum in Rhizoma Pinelliae Preparata from different companies.Conclusion The method is simple,reproducible and accurate,it can be used for the determination of alum residual amount in Rhizoma Pinelliae Preparata.
