Chemical composition of volatile and fixed oils from of Salvia argentea L. (Lamiaceae) growing wild in Sicily

Abstract

The chemical compositions of the essential oil and of the non-polar extracts (petroleum ether, dichloromethane) of the aerial parts (flowers, leaves and stems) of Salvia argentea L. were determined by GC-FID and gas chromatography-mass spectrometry analysis. 14-Hydroxy-α-humulene (40.1%) was recognised as the main constituents of the essential oil of S. argentea, together with 1,3,8-p-menthatriene (12.1%), globulol (7.4%) and β-sesquiphellandrene (5.8%). Tritriacontane (9.9% and 14.1%), heptacosane (8.4% and 10.5%), hentriacontane (8.3% and 10.9%), tetradecanal (8.4% and 10.2%) and methyldotriacontane (7.9% and 7.6%) were recognised as the main constituents of the extracts in petroleum ether and dichloromethane, respectively, whereas methyl linolenate (36.6% and 13.5%) and methyl myristoleate (10.5% and 18.5%) were recognised as the main constituents of the methylated extracts.

Profiling of Compositions of Essential Oils and Volatiles of Salvia limbata Using Traditional and Advanced Techniques and Evaluation for Biological Activities of Their Extracts

“…Also, the organic extracts of Sal . argentea were rich sources of other NH, i.e ., tritriacontane, heptacosane, hentriacontane, tetradecanal, methyldotriacontane, methyl linolenate, and methyl myristoleate . The dissimilarities observed in the corresponding chemical profiles can be attributed, apart from the different extraction technique, also to various geographical areas, climatic conditions and chemical composition of the soils of the habitats in which different species of the Salvia genus grow up.…”

Ethnobotanical Survey, Preliminary Physico-Chemical and Phytochemical Screening of Salvia argentea (L.) Used by Herbalists of the Saïda Province in Algeria

“…Among these numerous medicinal plants, our study focused on Salvia argentea belonging to the Lamiaceae family which is a plant species originating to the Mediterranean region, in northwest Africa (northern Algeria, Morocco, and Tunisia), southern Europe (Spain, Portugal, South Italy, Sicily, Malta, Albania, Bulgaria, Slovenia, Croatia, Bosnia, Kosovo, Montenegro, Serbia, Macedonia, and Greece) and Western Asia (Turkey) [ 2 ]. This family is known for its richness in numerous chemical substances capable of demonstrating various remarkable pharmacological activities [ 3 ].…”

“…This family is known for its richness in numerous chemical substances capable of demonstrating various remarkable pharmacological activities [ 3 ]. Among these substances, we mention the essential oils which mainly consist of oxygenated sesquiterpenes [ 2 , 4 ] and which are endowed with important biological properties, such as antimicrobial [ 5 , 6 ] and antioxidant activities [ 7 ].…”

Triterpenes from Salvia argentea var. aurasiaca and their antibacterial and cytotoxic activities

“…The known compounds were identified as 1β,3β-dihydroxyurs-9(11)-12-diene (6) [18], 3β-hydroxy-urs-9(11),12-diene (7) [19], 1β,3β,15α,28-tetrahydroxyurs-12-ene (8) [17], 1β,3β,11α,15α-tetrahydroxy-urs-12-ene (9) [17], and 3β-hydroxy-olean-9(11),12-diene (10) [20], by comparison of physical data with literature values and from spectroscopic evidence. In order to screen the antibacterial potential of compounds isolated from the acetone extract of the dried aerial parts (1-10), in addition to compounds previously isolated from the exudate of the fresh aerial parts (11)(12)(13)(14)(15)(16)(17)(18)(19) was the most active one with MIC values similar to gentamicin and vancomycin, used as standards (Table 2). Compound 19 showed potent inhibitory effect against S. epidermidis (MIC 3.9 µg/mL) and against E. coli and P. aeruginosa (MIC 7.8 µg/mL).…”

“…antioxidant, antibacterial, anticancer, anti-inflammatory and cytotoxic activities [11][12][13][14]. Salvia argentea L. is a plant species originating from the Mediterranean region [15]. and specifically in Algeria to treat respiratory diseases.…”
