Essential Oils of Four Himalayan<i>Nepeta</i>Species

Abstract

Abstract The chemical compositions of four Nepeta species collected from the Himalayan region of India have been determined for the first time by using a combination of GC, GC/MS and spectroscopic techniques. The oil of N. floccosa was found to be rich in neral (33.1%) and geranial (32.4%), N. govaniana oil contained 4aα, 7α, 7aα-nepetalactone (25.9%), germacrene D (20.5%) and β-elemene (17.5%) and N. discolor oil contained α-pinene (18.5%), β-pinene (12.6%), myrcene (10.7%) and linalyl acetate (12.3%). The oil of N. royleana was found to be rich in 1,8-cineole (75%)
