Aimed: Determine the potential of Cordia myxa L. leaf on inhibited α-glucosidase. Material: ELISA Kit, Ethanol 96\%, Colomn Chromatography, n-hexane, ethyl acetate, Glocobay{\textregistered}.\  Method: Sample from Cordia myxa L. leaf extracted by ethanol 96\% then evaporated to get the sticky extract. The sticky extract of Cordia myxa L. leaf fractionated by column chromatography with n-hexane, n-hexane: ethyl acetate (90:10; 80:20; 75:25; 70:30; 65:35; 60:40; 55:45; 50:50) Assay: The fractions assayed by ELISA (Enzyme-Linked Immunosorbent Assay) with acarbose (Glucobay {\textregistered}) as the comparator. Result: The results showed that the n-hexane fraction is the highest potency on inhibited α-glucosidase with the noncompetitive mechanism. The IC50 of n-hexane fraction is 0.53 ppm been while the acarbose is 6.85 ppm. Conclusion: The n-hexane fraction of Cordia myxa L. leaf has the highest potency to use for possible decrease blood glucose level.

The aim of this research is to determine of total flavonoid content in the Buni fruit (Antidesma bunius L. Spreng) extract. The extract was produced by stratified maceration method with the different solvent, i.e n-Hexane, Ethyl acetate and ethanol. The analysis of chemical compound using chemical reagent and Thin Layer Chromatography (TLC) method. The method is used to determines total flavonoid contains Buni fruit (Antidesma bunius L.) extract was based on the amount of Rutin Equivalent (RE) were used. The result shows that the flavonoid content higher in the n-Hexane extract is 10.72 \%, then ethyl acetate extract is 7.9 \% and 3.56 \% ethanol extract was counted to or as a Rutin.
