Abstract

Stone dammar, resin obtained from Shorea eximia, grows well in Kalimantan, Sumatra and Sulawesi. Its wood has been utilized, but the other parts of the plant have no economical value. The aim of this fundamental research was to extract the stone dammar using nonpolar and semipolar organic solvents, and to identify chemical constituents in stone dammar resin using py-GC/MS. Sesquiterpenes and terpene-O were the main compounds in stone dammar extracts using hexane or ethyl acetate. Some predominant sesquiterpenes are α-copaene, δ-cadinene, valencene, β-elemene and alloaromadendrene; and terpene-O were spathulenol and α-cadinol. High content of sesquiterpenes in these extracts indicated their potencies to be used as antimicrobial agent.
