Hydrodistilled Volatile Oils of the Flowers of Salvia leriifolia Bench. and Salvia multicaulis Vahl. as Two Growing Wild Plants in Iran

Abstract

The present report is a part of research to analyze and compare the constituent components of essential oil bearing plants in salt deserts of Iran comprising some species of Salvia genus. The volatile oils were extracted by hydrodistillation and were analyzed by gas chromatograph and gas chromatograph-mass spectrometer instruments. Recognition of the oil structure was afforded by comparison of the retention times and was confirmed by matching retention index, mass fragment and eight peak templates for each ingredient with those tabulated in authentic references. The flower oil of Salvia leriifolia Bench. was characterized by compounds constituting 97.6 % of the total oil, which were predominately g-terpenene (62.2 %), p-cymene (11.1 %), a-terpinene (7.3 %) and myrcene (5 %). Twenty one compounds representing 94.3 % of flower oil of Salvia multicaulis Vahl. were identified among them 1,8-cineol (25.3 %), a-pinene (18.3 %), camphor (12.4 %), camphene (8.4 %) and bornyl acetate (7.9 %) were the major ones. Accordingly, in the both volatile oils, monoterpenes predominate over sesquiterpenes.
