Chemical Constituents Of Allium Sativum (Garlic) And Curcuma Longa (Tumeric) Essential Oil

Abstract

Curcuma longa (turmeric) and Allium sativum (garlic) are spices that have been indicated to have several pharmacological potentials. The current study assessed the chemical constituents of turmeric and garlic. The essential oils were hydro distilled from the rhizomes of turmeric and bulbs of garlic in a yield of 0.80% (w/w) and 0.75% (w/w) respectively. The oils were analyzed by gas chromatography (GC) and gas chromatography and mass spectrometry (GC-MS). A total of fifty-four constituents were identified for both oils representing 96.3% (A. sativum) and 96.5% (C. longa). The main constituents of the oil of C. longa were ar-tumerone (28.6%),  atlantone (21.9%) and curlone (18.8%). The main constituents in A. sativum were sulfur derivative (94.1%), diallyldisulphide (15.7%), diallytrisulfied (53.9%), diallyltetrasulfide (11.7%), methylallytrisulphide (9.2%). This research shows that oil from turmeric and garlic comprises a total of 54 constituents and has 4 components in common.
