Background: Actinidia arguta leaves (AAL) are traditionally consumed as a vegetable and as tea in folk China and Korea. Previous studies have reported the anti-diabetic effect of AAL, but its bioactive components and mechanism of action are still unclear.

Aim Of The Study: This study aims to identify the hypoglycemic active components of AAL by combining serum pharmacochemistry and network pharmacology and to elucidate its possible mechanism of action.

Forty compounds were isolated and characterized from flower. Among them, twelve flavonoids showed higher α-glucosidase inhibition activities in vitro than acarbose, especially kaempferol. The molecular docking results showed that the binding of kaempferol to α-glucosidase (GAA) could reduce the hydrolysis of substrates by GAA and reduce the glucose produced by hydrolysis, thus exhibiting α-glucosidase inhibition activities.

Twenty glycoside derivatives and nine flavonoids from the leaves of () were isolated by column chromatography and characterized by nuclear magnetic resonance spectroscopy (NMR) and high performance liquid chromatography (HPLC). The contents of twenty glycosides and nine flavonoids from the extract of leaf (PL) were 173.3 mg g and 134.

Background: The over-expression of the anti-apoptotic protein Bcl-2 in cancer is associated with resistance to chemotherapeutic drugs. The phosphorylation of Bcl-2 is one mechanism by which anti-microtubule agents, such as paclitaxel or docetaxel, may inactivate Bcl-2. Although initially active in clinical studies, current anti-microtubule agents are only temporarily effective and the discovery of new agents is warranted.
