Type 2 diabetes mellitus (T2DM) is one of the most common degenerative disorders. For therapeutic use, herbs are commonly used in Indonesia for T2DM treatment, one of them is (Cosmos caudatus) kenikir{\textquoteright}s leaves. In previous studies, kenikir{\textquoteright}s leaves have high antidiabetic and antioxidant activity. However, a comparison of antidiabetic activity from many extracts of kenikir{\textquoteright}s leave is remain unclear. This study will compare the antidiabetic and antioxidant properties of various kenikir{\textquoteright}s leave extract. Kenikir{\textquoteright}s leaves are extracted by maceration methods for three days using three different solvents: boiling water, 50\% ethanol, dan ethanol 100\%. Then, phenolic and flavonoid content will be measured, as well as antioxidant properties by DPPH radical scavenging activity assay, and antidiabetic properties by α-glucosidase inhibition assay, also LCMS/MS will be used to predict the compound from each extract. The result shows that 50\% ethanol extract has highest phenolic and flavonoid content than others. It also has significantly higher antioxidant (p\<0.05) and antidiabetic (p\<0.05) properties than others. Meanwhile, LCMS/MS result of 50\% ethanol extract predicts 6 chemical component, that quercetin is the most dominant compound. 50\% ethanol extract of kenikir{\textquoteright}s leaves is superior from other extracts on phenolic and flavonoid content, antioxidant properties, and antidiabetic properties.
