Primary Metabolic Profile of Olive Leaves in Different Cultivars and Sites at Bikaner (Rajasthan)

DOI: 10.22161/ijeab.104.35

Abstract:
Due to the appreciable amounts of bioactive compounds in olive leaves and the effect of abiotic stress of arid area on their synthesis, this study evaluated the metabolic profile of primary metabolites in leaves of olive cultivars (‘Arbequina’, ‘Barnea’, ‘Coratina’ and ‘Koroneiki’) grown at two sites, viz., Lunkaransar and Napasar, located in Bikaner, Rajasthan (India). The total soluble carbohydrate content and protein content was determined by spectrophotometry. Lipid content was determined by solvent extraction and gravimetric method of quantification. Highest sugar content was found in ‘Coratina’ cultivar of Lunkaransar and protein content was found in ‘Koroneiki’ cultivar of Napasar. Maximum lipid content was found in ‘Arbequina’ cultivar of Napasar. Thus, it was possible to conclude that the cultivar and the site significantly affect the quantity of primary metabolites.
