Phytochemical examination on the different extracts of leaves and twigs of Holoptelea integrifolia (H. integrifolia) were carried out with varied polar organic solvents. The chemical constituents of crude extracts were separated and isolated by using chromatography technique and characterized by using spectroscopies of 1 H, 13 C and 2D NMR. Two known compounds, the stigmasterol (1) and octamethylcyclohexane-1,4-dione (2), and one new compound, di-myo-inositol (3) were isolated and characterized. Chemical constituent 2 and 3 has been reported for the first time in H. integrifolia; in addition, constituent 3 was new phytochemical finding.
