Abstract
ABSTRACT The study profiled the volatiles in Mentha longifolia, M. piperita and M. spicata and examined the effect of plant growth regulators (PGRs) - IAA, NaDK and SA on the modulations of volatile organic compounds (VOCs) in M. spicata. GC-MS was used to analyze and identify the compounds in hexane extractions from the selected Mentha sp. Sixteen metabolites belonging to monoterpenes, sesquiterpenes, esters, ethers, ketones, phenols and carbobicyclic compounds were detected. Some important metabolites viz., β-pinene, 1,8-cineol, 1,4-benzenediol, 2,5-dimethyl-, (Z)-β–caryophyllene, cis-β-farnesene, cis-muurola-4 (14),5-diene, germacrene D were found which increased in their relative concentrations compared to control after PGRs treatment.
