Phenolic Compounds from Holotrichia diomphalia Bates

从虫类中药蛴螬的乙酸乙酯提取物中分离得到6个化合物,其结构经波谱鉴定为3,5-二甲氧基-4-羟基苯甲酸(1),水杨酸(2),对羟基苯甲酸(3),香草酸(4),对羟基苯丙酸(5)和对羟基苯丙酸甲酯(6)。化合物1～6均为首次从该种动物药中分离得到。

Six compounds were isolated from the ethyl acetate extract of a medicinal insect, Holotrichia diomphalia Bates. They were identified as 3,5-dimethoxy4-hydroxylbenzoic acid （ 1）, salicylic acid （2）, 4-hydroxybenzoic acid （3） ,3-hydroxy4-methoxybenzoic acid （4）,4-hydroxyphenylpropionic acid （5）,and 4-hydroxyphenylpropionic methyl ester （6）, by using spectroscopic methods. All these compounds were isolated from this species for the first time.
