Chemical Composition of the Essential Oil and the Solvent Extracts of Curcuma Pseudomontana Rhizomes and in Vitro Evaluation of their Antioxidant and Anti-Inflammatory Activities

Abstract

The phytoconstituents of the essential oil isolated by hydrodistillation and solvent extracts (PE, BZ, DCM, EtOAc and EtOH) of mature rhizomes of turmeric (Curcuma pseudomontana) were analyzed by GC–MS. The major constituents identified in the oil and the extracts were Benzofuran (6.93%), γ-Curcumene (11.18%), β-Elemenone (22.14%), Germacrone (15.15%), Phenol, 2-Methyl-5-(1,2,2-trimethylcyclopentyl)- (29.58%), Germacrene (8.78%), Italicene (15.30%), Xanthorrhizol (56.52%), Pseudocumenol (24.56%) and Epicurzerenolne (4.95%). Analyzing the anti-inflammatory activity of essential oils (EO), and solvent extracts using HRBC stabilization and antioxidant activity. The results of GC MS analysis showed that while Pseudocumenol the major componenets in the essential oil. Xanthorrhizol is the major component in BZ, DCM and EtOH extracts of the matured rhizomes of C. psedomonata. The results of EO and the solvent extracts from Curcuma possessed good anti-inflammatory and antioxidant activities and hence can be used in natural preservative ingredients in food and/ or pharmaceutical industries.
