Abstract:
In light of the liver injury risk associated with the oral administration of Xianlin Gubao oral preparation, this study compared the differences in liver injury induced by two different extraction processes in rats and explored the correlation between hepatotoxicity and extraction process from the perspective of the differences in the content of the relevant components. Thirty male Sprague-Dawley(SD) rats were randomly divided into a normal group, tablet extract groups of different doses, and capsule extract groups of different doses, with 6 rats in each group. Each group received continuous oral administration for 4 weeks. The assessment of liver injury caused by different extracts was conducted by examining rat body weight, liver function blood biochemical indicators, liver coefficient, and liver pathological changes. In addition, a high-performance liquid chromatography(HPLC) method was established to simultaneously determine the content of icariin, baohuoside I, and bakuchiol in the extracts to compare the differences in the content of these three components under the two extraction processes. The results showed that both extracts caused liver injury in rats. Compared with the normal group, the tablet extract groups, at the studied dose, led to slow growth in body weight, a significant increase in triglyceride levels(P<0.05), a significant decrease in liver-to-brain ratio(P<0.05), and the appearance of hepatic steatosis. The capsule extract groups, at the studied dose, resulted in slow growth in body weight, a significant increase in aspartate aminotransferase levels(P<0.05), a significant decrease in body weight, liver weight, and liver-to-brain ratio(P<0.05), and the presence of hepatic steatosis and inflammatory cell infiltration. In comparison, the capsule extraction process had a higher risk of liver injury. Furthermore, based on the completion of the liquid chromatography method, the content of icariin and baohuoside Ⅰ in the capsule extract groups was 0.83 and 0.81 times that in the tablet extract groups, respectively, while the bakuchiol content in the capsule extract group was 29.80 times that in the tablet extract groups, suggesting that the higher risk of liver injury associated with the capsule extraction process may be due to its higher bakuchiol content. In summary, the differences in rat liver injury caused by the two extracts are closely related to the extraction process. This should be taken into consideration in the formulation production and clinical application.
