Ham)果实的95%乙醇提取物中共分离鉴定了16个化合物(1~16a/16b)。其中, 甾醇类化合物1个, β-谷甾醇 (β-sitosterol, 1); 三萜类化合物1个, 白桦脂酸 (betulinic acid, 2); 酚酸类化合物8个, 顺式异扁柏脂素 (cis-hinkiresinol, 3)、4°-甲氧基顺式异扁柏脂素 (4°-O-methyl-cis-hinokiresinol, 4)、香草酸 (vanillic acid, 5)、没食子酸甲酯 (methyl gallate, 6)、3-甲氧基没食子酸 (3-O-methyl gallic acid, 7)、丁香醛 (syringaldehyde, 8)、丁香酸 (syringic acid, 9)、对羟基苯甲酸甲酯 (methylparaben, 10); 苹果酸酯类化合物9个, 4-ethoxy- 3-hydroxy-4-oxobutanoic acid (11)、苹果酸二甲酯 (dimethyl malate, 12)、苹果酸甲基乙基酯 (ethylmethyl malate, 13a/13b)、苹果酸乙基正丁基酯(butylethyl malate, 14a/14b)、苹果酸二正丁基酯 (bibutyl malate, 15)、苹果酸甲基正丁基酯 (butylmethyl malate, 16a/16b)。化合物14a/14b为新化合物; 化合物11为新天然产物; 化合物3~16a/16b为首次从无瓣海桑植物中分离得到; 化合物3、5~16a/16b为首次从海桑属植物中分离得到。
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.
