%X The Gunungkidul region has a unique topography, characterized by the presence of  karst landscapes. The environmental conditions in karst areas differ from those in  non-karst environments, which allows for differences in secondary metabolite  compounds. Beluntas leaves (Pluchea indica Less.) are one of the plants that grow  in the karst area of Gunungkidul and are used by the local community to promote  breast milk production. This study aims to determine the profile of secondary  metabolite compounds and the most effective solvent for extracting secondary  metabolites from beluntas leaves in the Gunungkidul karst area. The study used  beluntas leaf samples from the Tepus area of Gunungkidul. The extraction solvents  used were methanol (polar), ethyl acetate (semi-polar), and n-hexane (non-polar)  with the GC-MS method. The identification results were analyzed descriptively and  qualitatively. The results showed 77 different types of secondary metabolite  compounds. Compounds with an area percentage greater than 15% in the methanol  extract were stigmasterol (19.63%), ethyl iso-allocholate (18.37%), and phytol  (15.40%). Compounds with an area percentage greater than 15% in the ethyl acetate  extract were phytol (22.41%), ethyl iso-allocholate (22.13%), and stigmasterol  (16.41%). Compounds with an area percentage greater than 15% in the n-hexane  extract were stigmasterol (20.59%) and lupeol (19.65%). Based on these results, it  can be concluded that the solvent which extracted the most compounds was nhexane,  with a total of 50 different compounds. The most abundant group of  compounds in all three solvents was terpenoids. Stigmasterol was the compound  with an area percentage above 15% in all solvents.
