Medicines in the DPP4 inhibitor class include sitagliptin, saxagliptin, linagliptin, and alogliptin. However, research data on the mechanism of action of the active ingredients of WBG on DPP4 are also limited. Therefore, this in silico study aimed to idenfy acve ingredients with strong or potential effects on the DPP4 target for andiabec acvity of WBG.

In everyday life, nature has given us countless useful medicinal plants. Among the common plants in Vietnam, the custard apple (Annona squamosa L.) has not been mainly used as a fruit but also traditionally as a medicine. However,studies on morphological characteristics remain limited in Vietnam as well as around the world. Determine the morphological and microscopic characteristics, and physicochemical features of A. squamosa leaves.
