Background: Binahong is a plant that has the potential to be used as a traditional herbal medicine in Indonesia, and has several kinds of classes of compounds, one of them is a flavonoids glycosides (vitexin). Previous research reported that binahong leaves have pharmacological activities as antihyperglycemic, antihyperlipidemic, antibacterial, and others. A traditional plant that has proven efficacious needs to be standardized to ensure the quality and its safety. Objective: This study aimed to characteristics of binahong leaves simplicia obtained from Bogor, West Java. Materials and Methods: The crude extract was obtained by the maceration method using 40\%, 70\%, and 96\% ethanol solvent. The selected extract then standardized, which includes macroscopic and microscopic observations and sets the standard parameter values binahong leaf extract. Parameters LCMS to identify active compounds semiquantitatively. Results: The yield of binahong ethanol extract from 40\%, 70\%, 96\% showed a value of 10.9\%, 11.4\%, and 12.32\%, respectively. From these results, 96\% ethanol extract has proceeded for standardization. Macroscopic observation results showed that binahong leaves simplicia has a fine and notched form with 5-10 cm long and 3-7 cm diameter. The microscopic binahong leaves contain palisade tissue, parenchymal tissue, chlorophyll grains, rosette Caoxalate crystals, and spiral type. Phytochemical screening of binahong leaves showed the presence of alkaloids, flavonoids, saponins, tannins, steroids, and phenolic compounds.The standardization of binahong leaves ethanol extract down showed a levels of ethanol-soluble extract\> 14.8\%, water-soluble extract content \> 13.5\%, drying \< 10\%, water content \< 8.9\%, total ash content \< 7.2\%. LCMS profiles showed that ethanolic extract 40\%, 70\%, and 96\% all contained vitexin at retention time 5.02 minutes, and m/z values 433.1111. Conclusion: 96\% ethanolic extract of binahong leaves contains vitexin with pharmacognostic parameters carried out following the standards listed in the Indonesian herb pharmacopeia.

Introduction: Diabetes Mellitus is a disease that has a high prevalence in Indonesia. About 90-95\% of all diabetes cases were caused by the failure or incapability of insulin target cells to respond to the insulin in normal state. The use of glibenclamide antidiabetic drugs with herbs has been occurred frequently in the community. Vitexin, one of active compounds in binahong (Anredera cordifolia (Ten.) Steenis) leaves, has been known to have an antidiabetic effects. This study aimed to determine the molecular docking interaction of glibenclamide and vitexin in binahong leaves against CYP3A4 as antidiabetic drug. Method: Molecular docking methods were carried out using Autodock Vina software and interaction was visualized using discovery studio. Results: The study indicated that the value of glibenclamide complex free energy with CYP3A4 was -3.2 kcal/mol and the stability has increasing to -4.4 kcal/mol after docked with vitexin. The glibenclamide and vitexin complexes had 7 Pi alkyl hydrophobic bonds, 1 hydrocarbon hydrogen bond 1 Pi-cation electrostatic interactions, other interactions between Pi bond and sulfur atoms in cysteine amino acid residues, Pi bond interactions in phenylalamin aromatic groups with electron pairs oxygen atom. Conclusion: This study concluded that vitexin could improve glibenclamide stability.
