PISTAGREMIC ACID, A NOVEL ANTIMICROBIAL AND ANTIOXIDANT ISOLATED FROM Pistacia integerrima

摘要

In the present research, a new triterpenic compound was isolated from galls of Pistacia integerrima. The structure of this novel compound was identified using modern sophisticated spectroscopic techniques such as HR-EI-MS, FAB, 1D, and 2D NMR spectral data and single crystal X-ray diffraction methods. The compound was confirmed to be 2-methyl-6-(4,4,10,13,14-pentamethyl-3-O-2,3,4,5,6,7,10,11,12,13,14,15,16,- 17-tetradecahydro-1H-cyclopenta[a]-phenanthren-17-yl)hept-2-enoic acid and named pistagremic acid, which has antimicrobial and antioxidant properties.
