Abstract: Preparation of glucuronide conjugates of etofesalamide[N-(4-ethoxyphenyl)-2-hydroxyl-benzamide], a novel drug for acne therapy, in rabbit was discribed. Urine samples from 0 to 12 h were collected after single oral administration of 400 mg etofesalamide to two rabbits. The samples were lyophilized and extracted with methanol, and then etofesalamide-2-glucuronide in them was prepared with semipreparative HPLC. The molecular structure of this compound was confirmed by electrospray ion trap mass spectrometry and 1H NMR.

Key words: N-(4-Ethoxyphenyl)-2-hydroxyl, benzamide, Etofesalamide-2-glucuronide, HPLC, Electrospray ion trap mass spectrometry
