Antiulcer secondary metabolites from , family Elaeocarpaceae, supported by studies.

has a very potent analgesic effect, especially to a δ-opioid receptor, but its antiulcer activity has not yet been validated. Therefore, the present study was carried out to evaluate the antiulcer potential of the total methanolic extract and its derived fractions of the aerial parts of the plant using an indomethacin-induced gastric ulcer method. One new compound, grandisine H (1), and five known compounds, -methoxy benzaldehyde, methyl gallate, kaempferol, quercetin and heterophyllin A (2-6), were isolated from the ethyl acetate fraction, which was the most potent one with an ulcer index value of 5 ± 1.
