DETERMINATION OF THE COMPOUNDS EXTRACTED FROM DIPTEROCARPUS ALATUS IN DAILOC DISTRICT, QUANGNAM PROVINCE

Abstract

This article will reveal the content and chemical composition of Dipterocarpus alatus. Nineteen compounds of the ethyl acetate extract, seventeen constituents of the toluene extract and twenty constituents of the methanol extract of Dipterocarpus alatus were identified by using organic solvents for extraction and gas chromatography with massspectrometry GC/MS. There were some similar constituents in the three extracts of organic solvents with high percentage such as 1H-Cycloprop[e]azulene, decahydro-1,1,7-trimethyl-4-tetramethyl from 74,94% to 76,87%; 1H-Cyclopenta[1,3]cyclopropa [1,2]benzene,2,3,3aà,3bà,4,5,6,7octahydro-7-methyl-3- from 2,63% to 4,08%; Isocaryophyllene from 3,82% to 4,78%; (-)-Spathulenol from 1,78% to 1,90%; Velleral from 0,91% to 1,97%. Chemical components from crystallization of sediment methanol were found to differ from those of three solvent extracts above. There are 49 compounds in the crystal and the highest percentage compound found was Lupeol.
