Morphological characterisation and agronomical parameters of different species of Salvia sp. (Lamiaceae)

Abstract

The aim of this work is to assess the morphological characteristics and parameters of biomass production, such as fresh and dry matter weight (FMW and DMW, g/plant), yield of dry matter (YDM) in terms of ton/ha, essential oil content (EOC, mL/100 g) and yield of essential oils (YEO) expressed as L/ha of the following plants Salvia verbenaca, Salvia argentea, Salvia lavandulifolia, Salvia pratensis, Salvia sclarea, Salvia triloba and Salvia officinalis. Except for Salvia argentea (S2) all other species have adapted to the south Brazilian climate conditions, with morphological differences among the species evaluated. In terms of DMW and YDM, S. officinalis was found to be the most productive species with 445.83 g/plant and 11.14 ton/ha. The higher essential oil content and yield was observed for S. officinalis, affording 1.99 mL/100 g and 221.74 L/ha, respectively. Chemical characterisation of the essential oils obtained from hydrodistillation was performed through GC and GC/MSD analyses, which revealed for most of the species studied, α e β-thujone, camphor and 1,8-cineole as major compounds, apart from S. sclarea, for which linalool, linalyl acetate and α-terpineol were the major components.

Evaluation of Immunostimulant Activity of Spirulina platensis (Arthrospira platensis) and Sage (Salvia officinalis) in Nile Tilapia (Oreochromis niloticus)

“…Salvia officinalis is cultivated in numerous countries for its dried leaves which are used as raw material in medicine, food-industry and perfumery [50]. It has been found that the essential oil and leaves extracts of SO have a wide range of antimicrobial effects which may be due to its particular chemical constituents [51]. The present observations revealed that the leaves of SO prevented P. aeruginosa.…”

In vitro effects of Salvia officinalis L. essential oil on Candida albicans

“…The essential oil and leaves extracts of S. officinalis L. has been documented to have wide range of antimicrobial effects [6] . The antimicrobial actions are suggested due to its particular chemical constituents dominated by oxygenated hydrocarbons, monoterpene hydrocarbons and sesquinterpene hydrocarbons particularly 1-8, cineole, α-β-thujone and borneol [9] .…”

“…sage, Salvia officinalis L. (S. officinalis), is a perennial plant native to the Mediterranean region. Extracts from Sage have been reported to have a wide range of medicinal properties including spamolytic, antimicrobial and astringent [6][7][8] . Gas chromatography and mass spectrometry analysis have revealed S. officinalis L. essential oil to be composed mostly of oxygen-containing monoterpenes with major constituents such as 1, 8-cineole, β-thujone, borneol, β-elemene and camphor [9] .…”

In vitro Evaluation of the Antimicrobial Potential of Salvia officinalis L. against Oral Pathogens

“…Among the available biodiversity, what stands out is the Salvia officinalis L., one of the most used plant species in traditional medicine, in function of its biological properties, as an antioxidant 9,10 antimicrobial 10,11 , anti-inflammatory 12.13 , and antitumor 9.14 , resulting from the action of various chemical compounds present in the plant, including diterpenes, triterpenes, flavonoids 15 and phenolic acids 16 .…”

“…Despite its use being widespread and its chemical characterization and antimicrobial activity documented in some studies [16][17][18][19][20][21] , there is still the need of scientific studies that demonstrate the use of this plant on oral diseases 22 . In this sense, considering the need for new studies about the antimicrobial effect of S. officinalis, the aim of this work was to evaluate in vitro the antimicrobial potential of this plant outside the oral pathogens.…”
