Abstract:
In order to establish the standardized processing technology of the hot water washing of Euodiae Fructus, this study, based on the traditional processing method of hot water washing of Euodiae Fructus recorded in ancient works and modern processing specifications of traditional Chinese medicine decoction pieces, took the yield of decoction pieces and the content of main components as the indicators and optimized the processing conditions by orthogonal test based on the results of single factor investigation. At the same time, electronic tongue technology was used to analyze the change law of the taste index of Euodiae Fructus during the hot water washing. The results of the single factor investigation showed that the content of the main components in Euodiae Fructus showed some regular changes during the processing. Specifically, the content of chlorogenic acid, hyperin, isorhamnetin-3-O-rutinoside, isorhamnetin-3-O-galactoside, and dehydroevodiamine decreased significantly, with average decreases of-23.75%,-27.80%,-14.04%,-14.03%, and-13.11%, respectively. The content of limonin increased significantly with an average increase of 19.83%. The content of evodiamine, rutaecarpine, evocarpine, and dihydroevocarpine showed fluctuating changes and generally increased, with average variation amplitudes of 0.54%,-3.78%, 2.69%, and 5.13%, respectively. The orthogonal test results showed that the optimum processing parameters for the hot water washing of Euodiae Fructus were as follows: washing time of 2 min, the solid-to-liquid ratio of 1∶10 g·mL~(-1), washing temperature of 80 ℃, washing once, and drying at 50 ℃. After the hot water washing processing, the average yield of Euodiae Fructus pieces was 94.80%. The content of limonin, evodiamine, and rutaecarpine was higher than those of raw pro-ducts, and the average transfer rates were 102.56%, 103.15%, and 105.16%, respectively. The content of dehydroevodiamine was lower than that of the raw products, and the average transfer rate was 83.04%. The results of taste analysis showed that the hot water washing could significantly reduce the salty, astringent, and bitter tastes of Euodiae Fructus. This study revealed the influence of the hot water washing on the content of main components and taste of Euodiae Fructus, and the processing technology of the hot water was-hing of Euodiae Fructus established in this study was stable, feasible, and suitable for industrial production, which laid a foundation for clarifying its processing principle and improving the quality standard and clinical application value of decoction pieces.
