Studies on Essential Oils. Part 15. GC/MS Analysis of Chemical Constituents of Leaf Oil of Lippia alba (Mill.) from North India

Abstract

The oil isolated by hydrodistillation from the leaves of Lippia alba growing in plain regions of North India, was analyzed by GC and GC/MS. Fifty-nine components were identified accounting for approximately 98% of the total oil. Myrcene (26.4%) was found as a major component followed by geranial (9–8%), neral (6.4%), 6-methyl-5-hepten-2-ol (5.9%), β-caryophyllene (4.3%), junenol (4.2%), geraniol (3.9%), 6-methyl-5-hepten-2-one (3.3%), linalool (3.2%), etc.
