Comparison of Chemical Composition, Antifungal and Antibacterial Activities of Two Populations of Salvia macilenta Boiss. Essential Oil

Abstract

Salvia macilenta Boiss. is a fragrant subshrub which grows wild in some regions of Iran. In this work, we contrasted essential oil contents and components of two wild populations under two different ecological situations (Kerman and Baluchistan Provinces, Center and South East of Iran, respectively). For the first time the antibacterial and the antimycotic properties of these essential oils were also evaluated against seven bacterial and fungal strains. The essential oils were isolated by hydrodistillation method and the chemical compositions of the samples were examined by GC and GC-MS. Kerman (K) specimen was found to be rich in α-pinene (29.0%), p-cymene (10.7%), veridiflorol (9.1%), α-eudesmol (8.7%), bornyl acetate (7.3%) with lesser concentrations of borneol (4.9%). Principal components were identified as α-eudesmol (35.6%), α-pinene (7.7%), bornyl acetate (7.6%), (E)-nerolidol (6.5%) and veridiflorol (5.9%) from Baluchistan (B) sample. Oxygenated sesquiterpenes were found to be the principal class of components in the oil of Baluchistan sample (53.0%) whereas monoterpene hydrocarbons were the main class in Kerman specimen (46.6%). The results demonstrated that the variety in the volatile compounds could be considered as chemotaxonomic importance and it may be ascribed to their different ecological and geographical source.

Activity of Salvia dolomitica and Salvia somalensis Essential Oils against Bacteria, Molds and Yeasts

“…The major components of both examined EOs such as 1,8 cineole, bornyl acetate, β -caryophyllene, α -pinene, camphor were shown to possess antifungal activity [ 16 ], in particular EOs containing such components were effective against Fusarium spp. [ 17 ], Heterobasidion parviporum [ 18 ] and EOs from plants rich in bornyl acetate and α -pinene showed antimycotic action [ 19 , 20 ].…”

Formulation of nanoemulsion carriers containing Pennyroyal (Mentha pulegium) and Gijavash (Froriepia subpinnata) essential oils for enriching Doogh (Iranian dairy drink)

“…The FSLB is an annual plant with white flowers and a height of 20–110 cm. In traditional medicine, this plant is used against liver disorders and as a carminative, antispasmodic, diuretic, sedative, and tonic agent [ 9 , 10 ]. The Mentha pulegium plant is mainly characterised by a pungent minty scent, presenting a prostate stance except during flowering when it becomes upright, and blooming pink to blue flower clusters.…”

A GC-MC analysis of chemical compounds and identification of the antibacterial characteristics of the essential oil of two species exclusive to Iranian habitats: New chemotypes

“…The most important reported compounds of the EO of this species are monoterpenes such as α-pinene, limonene, geraniol, neral, and citral [ 29 , 34 , 39 , 41 – 46 ] (7;; 5;. Plant EOs are affected by various factors such as genetics, evolution, environmental conditions, geographic changes, physiologic factors, and harvest time [ 44 , 47 ]. Thus, plants that vary genetically and climatically and grow in different habitats can be considered strong sources to identify new chemotypes [ 28 ].…”
