Cassia twig is a dry twig of
, a
plant. Astragalus L is one of the largest genuses of flowering plants in the
family. Roots of A. membranaceus Bge. var. mongholicus (Bge.) Hsiao, A. membranaceus (Fisch.) Bge. Chinese herb couple refers to the matching of two herbs in pairs, mostly with synergistic effects or toxicity reduction. This Chinese herb couple (Cassia twig-Astragalus) come from the classic famous book "Zhang Xichun's book on Chinese herb couple", which is widely used to treat diabetes. Moreover, both Cassia twig and Astragalus belong to the homology of medicine and food. However, its mechanism is still unclear. The study identified the effective components of Cassia twig-Astragalus by UPLC-Q-TOF-MS/MS and investigated the mechanism of Cassia twig-Astragalus in treating diabetes by virtue of network pharmacology, molecular docking and experimental verification. Firstly, based on UPLC-Q-TOF-MS/MS and network pharmacology, a total of 10 active ingredients of Astragalus and 6 active ingredients of Cassia twig were screened, and a total of 13 key targets were obtained. There were 64 targets at the intersection of Cassia twig-Astragalus with diabetes, mainly including IL-17, TNF, NF-κβ, AGE-RAGE signaling pathway, etc. It mainly involves the response of cells to insulin stimulation, the response to insulin and the positive regulation of cell adhesion. Secondly, molecular docking results showed that quercetin has good binding activities with AKT1 and TNF. Calycosin has good binding activities with AKT1, TNF and CAV1. Formononetin has good binding activities with TNF and IL-6. Isorhamnetin has good binding activities with AKT1, TNF and IL-6. Finally, the animal experiments showed that Cassia twig-Astragalus could improve the body weight, blood glucose and glucose tolerance in diabetic rats. After the intervention with Cassia twig-Astragalus, the inflammatory factors (IL-10, TNF-α, IL-6) were significantly improved in diabetic rats, which also effectively reduced TG and TC.Communicated by Ramaswamy H.
