Pistacia integerrima

The steam-distilled oil derived from the galls of Pistacia integerrima was analyzed by chromatography and spectral techniques. The oil was found to be rich in a-pinene (13) (21.8%), P-pinene (14) (16.2%), a-phellandrene (15) (15.5%), and A3-carene (16) (11.1%). The other main constituents characterized were P-phellandrene (17), y-terpinene (18), a-terpineol (19), and P-terpineol (20) as well as a-ocimene (21) and P-ocimene (22). This steam-distilled oil was shown to possess CNS-depressant activity [75]. 

Some members of the lanostane class from Pistacia integerrima (Anacardiaceae) galls proved to be very potent. When administered at only 5 mg/kg i.p. they reduced carrageenan inflammation. Pistacigerrimone A (70%) and pistacigerrimone D (62%) were especially effective [67].
