Abstract:
Under the traditional processing theory "wine processing could promote the efficacy", Rhubarb after wine processing could treat the upper energizer diseases such as red swelling, and breath sores. Processing changes the medicinal properties of rhubarb, and thus results in different focuses in clinical application. In this study, a sensitive and specific method was developed for the determination of aloe-emodin, rhein and emodin in rats tissue. Rhubarb raw materials and its wine processed decoction were given to SD rats respectively by gavage administration, and then the contents of aloe-emodin, rhein and emodin in the tissues (heart, lung, brain, liver, kidney) were determined by HPLC-MS to explore the effect of wine processing on free anthraquinones in rat tissues. Experimental results showed that wine processing can significantly change the distribution of aloe emodin, rhein and emodin in rats in vivo, and the distribution of these components was increased in heart and lung tissues.There was no significant change of distribution in the liver and the kidney as compared with raw product group, and these three ingredients were not detected in the brain, indicating that aloe-emodin, rhein, emodin can not pass through the blood brain barrier.Therefore, wine processing had greater effect on distribution of free anthraquinones in rat tissues.This also verified the theory of traditional Chinese medicine, providing experimental basis for rhubarb processing mechanism.
