Terpenoid from curcuma longa

ABSTRACT

Three triterpenoid compounds were isolated from methanol portion of petroleum ether extract of Curcuma longa L. [Zingiberaceae] rhizomes and were identified by different spectral analyses. Biological activity of petroleum ether extract and the three compounds were evaluated against adult females of Tetranychus urticae Koch mites. Petroleum ether extract, compounds I and II showed higher toxicity towards the adult females, while compound III was found to be most effective on the reproduction of the adult females. Essential oil of the rhizome was extracted and analyzed by GC/MS. The oil showed antioxidant activity
