Abstract: A total of 95% ethanol extract from the fruits of Sonneratia apetala Buch. Ham was isolated by a variety of chromatographic methods, and the structures of the isolated compounds (1~16a/16b) were elucidated by a series of spectroscopic techniques. These structures were identified, including one phytosterols, β-sitosterol (1); one triterpenoid, (betulinic acid, 2); eight phenolic acids, cis-hinkiresinol (3), 4°-O-methyl-cis-hinokiresinol (4), vanillic acid (5), methyl gallate (6), 3-O-methyl gallic acid (7), syringaldehyde (8), syringic acid (9), methylparaben (10); and nine malate compounds, 4-ethoxy-3-hydroxy-4-oxobutanoic acid (11), dimethyl malate (12), ethylmethyl malate (13a/13b), butylethyl malate (14a/14b), bibutyl malate (15), butylmethyl malate (16a/16b). The compounds 14a/14b were new; compound 11 was a new natural product; the compounds 3~16a/16b were obtained from S. Apetala for the first time; and the compounds 3, 5~16a/16b were obtained from genus Sonneratia for the first time.

Key words: Sonneratia apetala Buch. Ham, triterpenoid, phenolic acids, malate, chemical constituents
