Study on fingerprint of Chuanxiong Rhizome standard decoction / 中草药

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.
