Quantification of phytochemicals and its association study with leaf oil percentage in different genotypes of Ocimum tenuiflorum L.

Abstract

Six genotypes of holy basil collected across India were analysed for quantification of phytochemicals on leaves and its association with leaf oil percentage were examined and presented in this article. The maximum ascorbic acid and β carotene content in leaf (89.51 & 5.93 mg 100 g-1) was recorded in West Godavari Local genotype followed by Cim-Ayu and Anand Collection 2 (86.37 & 4.66 mg 100 g-1). The highest total phenols in leaf (360.23 mg 100 g-1) was recorded in genotype Anand Collection 2 followed by West Godavari Local (308.60 mg 100 g-1). Anand Collection 2 recorded the highest (3.70%) per cent oil from leaves on dry weight basis which was on par with Cim-Ayu (2.98%) and West Godavari Local (2.97%). Phenols content in leaf (0.844) and aroma score of leaves (0.811) showed significant positive association with per cent oil from leaves on dry weight basis.
