Aims: To study the chemical composition of the stems of Allophylulogipess. Methods: The ethyl acetate fraction of stem methanol extract of S. heterophylla was chromatographed, and the structures of the compounds were determined according to the spectral data and physical and chemical properties. Results: 25 compounds were isolated and identified as ycloart-24-ene-3β, 26-diol (1), 3-oxotrirucalla-7,24-dien-21-oicacid (2), zizyberenalic acid (15) -eudesmene-1β, 6a-diol (5), 4 (15) -eudesmene-1β, 8a-diol -diol (7), methyl Ester (8), betulin (9), betulin aldehyde (10), betulinic acid (11), 3β-hydroxy-5a, 8a-epidioxyergosta-6,22 -dien (12), 3-oxo-19a-hydroxyurs-12-en-28-oicacid (13), ursolic acid (14), scopolactone (15) (17), vanillin (18), tumeric (19), 2 ’, 6’- dihydroxy- 4’-methoxyacetophenone (20), p- (aminoalkyl) ), 1-Op-coumaroylglucose (23), β-sitosterol (24), poriferast-5-ene-3β, 4β-diol (25). Conclusion: All compounds were isolated from Allophylulogipess for the first time.
