Abstract:
To prepare processed Curcumae Longae Rhizoma standard decoction, establish its quality standard, provides quality reference for formulated Jianghuang granules and lay a foundation for standard decoction research for the pieces containing volatile oil. Thirteen batches of processed Curcumae Longae Rhizoma standard decoctions were prepared according to the preparation requirements for standard decoction of Chinese herbal medicine containing volatile oil. With curcumin as the detection index, the transfer rate and extraction ratio were calculated; the pH value was determined and HPLC fingerprint analysis method was established. The results showed that the transfer rate ranged from 0.67% to 2.24%; the extraction rate was at a range of 9.95% to 18.36% and pH value was 3.86 to 6.05. Then the Similarity Evaluation System for Chromatographic Fingerprint of Traditional Chinese Medicine (2012A) was used to analyze and compare the fingerprint. Sixteen common peaks were determined and three were identified including bisdemethoxycurcumin (peak 7), demethoxycurcumin (peak 8) and curcumin (peak 9). Moreover, the similarity was over 0.78 in the similarity evaluation of 13 batches of samples. HPLC fingerprint analysis method of processed Curcumae Longae Rhizoma standard decoction was established, showing good precision, stability and repeatability with certain identification effect, suitable for the quality control of formulated Jianghuang granules.
