abstract: 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.
