ABSTRACT
Objective To prepare 15 batches of Chuanxiong Rhizoma standard decoctions and evaluate its quality. Methods According to preparation conditions of the TCM standard decoction, 15 batches of Chuanxiong Rhizoma standard decoction were prepared; The content of ferulic acid chlorogenic acid and caffeic acid in Chuanxiong Rhizoma standard decoction were determined by using HPLC; The fingerprint of Chuanxiong Rhizoma standard decoction was established by using UV-visible spectrophotometry and infrared spectroscopy; And diverse batches of Chuanxiong Rhizoma standard decoction fingerprint were comparative analyzed by using the correlation coefficient method and double-index analysis method. Results The results of 15 batches of samples revealed that the transfer rate of ferulic acid ranged from 0.485 7% to 0.749 5 %, the transfer rate of chlorogenic acid ranged from 0.316 0% to 0.565 6%, the transfer rate of caffeic acid ranged from 0.017 7% to 0.050 4%, and extract rate was at the range of 18.82%-27.60%. Compared with the UV and IR standard fingerprint, the similarity of Chuanxiong Rhizoma standard decoction fingerprint was more than 0.990 and 0.911 respectively. The results of double-index analysis showed that the common peak rate of each lot of Chuanxiong Rhizoma standard decoction was more than 51.72%. Conclusion This quality evaluation method can be used for the systematic evaluation of Chuanxiong Rhizoma standard decoction. It also provides a theoretical reference preparation for the formulation of quality standard of for the formulation of quality standard for Chuanxiong Rhizoma preparations such as Chuanxiong Rhizoma dispensing granules.
ABSTRACT
Objective: To establish the quality standards of Reduning Injection (RI) based on UV fingerprint, and improve the quality standards of RI. Methods: Full wavelength UV-vis spectrophotometer was used to scan the 15 batches of RI, a reference fingerprint was established, correlation coefficient method was used to calculate RI sample fingerprint and control fingerprint similarity, and the 14 batches of samples were verified. Results: The five batches of RI were within the validity period, their UV fingerprints were in line with the requirements, similarity was all above 0.902, while the absorbance values were in the ranges of 0.693-0.781 (323 nm), 0.323-0.370 (267 nm), 0.957-1.067 (236 nm), 0.902-1.013 (226 nm), 0.953-1.075 (218 nm), and 0.926-1.052 (211 nm); In addition the expired nine batches of RI, similarity is less than 0.902 or the absorbance value does not meet the standard. Conclusion: UV fingerprint method can be used as a simple and accurate method of quality evaluation for the quality control of RI.
