Chemical Variation in the Essential Oil of<i>Salvia bracteata</i>Banks &amp; Soland from Iran

Abstract

Abstract The genus Salvia L. (Lamiaceae) contains 65 species and hybrids that are distributed all over Iran, eighteen of which are endemics. In this study, hydrodistilled essential oils from the aerial parts of eleven population of Salvia bracteata Banks & Soland were investigated mainly by a combination of GC and GC-MS, for the first time. Forty-six components were identified in the oils. The main constituents of the essential oils were β-caryopyllene (10.7–41.6%), y-muurolene (27.1–36.3%), bicyclogermacrene (1.8–9.9%), caryophyllene oxide (1.5–9.6%) and ot-humulene (1.1–9.4%). Although the main components of all the oils are common, but there are some differences between the percentages of major components and also minor constituents.
