Determination of Essential Oil Bioactive Components and Rosmarinic Acid of Salvia officinalis Cultivated under Different Intra-row Spacing

Abstract

Salvia officinalis, known also as sage, is a medicinal plant belonging to the Lamiaceae family that spreads all over the word in several countries. The demand for the raw material and extracts of this plant is increasing due to its numerous applications in pharmacy, food and herbal tea production. The present study investigated for the first time the effect of 15, 30 and 45 cm intra-row spacing (plant density) on the main constituents of sage essential oils and rosmarinic acid content. The highest content of essential oils (2.7%) and rosmarinic acid (2.0%) were obtained in plants grown using 15 cm planting space. Likewise, close spacing resulted also in a substantial content of 1,8-cineole (47-50%, GC/FID; 55-60%, GC/MS). This work indicated that 1,8-cineole chemotype was a dominant character of cultivated S. officinalis in south of Jordan. In general, the percent of α-thujone in essential oil was not affected by intra-row spacing. However, the percent of β-thujone decreased from (2-3%, GC/MS) in plants grown using 15 cm intra-row spacing to (1-2%, GC/MS) in plants grown using 30 and 45 cm intra-row spacing. The highest content of α-and β-pinene was recorded in plants grown using 45 cm planting space (8-10%, GC/FID; 5-6% GC/MS). Based on GC/MS, camphor compound was enriched (9-10%) in sage plants grown under 15 cm spacing and greater than in plants grown under 30 (6-7%) or 45 cm (5-6%) spacing. The results make the potential use of sage extracts in the treatment of some human disorders or illness an area of further research.

Chemical Composition, Antioxidant and Antimicrobial Activities of Essential Oil fromCrithmum maritimumCultivated in Tunisia

“…The leaves are also used in folk medicine as antiscorbutic, tonic, carminative, diuretic, depurative and vermifuge 4,[9][10][11][12] Several studies about C. maritimum essentials oils were reported. In the other hand, variable natural climatic conditions can affect the essential oil contents in plants 13 .…”

Bioassay guided isolation of mosquito larvicidal compound from acetone leaf extract of Elaeagnus indica Servett Bull and its in-silico study

“…Thujone has been found to be primary constituent of essential oils of several plants such as, Artemisia incana (Mojarrab et al, 2013), Artemisia deserti, Artemisia oliveriana (Rustaiyan et al, 2000), Artemisia kermanensis (Ganjali and Pourramezani Harati, 2012), Artemisia vulgaris (Govindaraj and RanjithaKumari, 2013), Commiphora tenuis (Asres et al, 1998), Croton urucurana (Simionatto et al, 2007), Mentha nativa (Bascope and Sterner, 2010), Mentha longifolia, Rosmarinus officinalis (Mohkami et al, 2014), Salvia fruticosa (Topcu et al, 2013), Salvia officinalis (Miladinovic and Miladinovic, 2000;Hadri et al, 2010;Monakhova et al, 2011;Darwish et al, 2013;Baj et al, 2013), Tanacetum santolinoides (Shazly et al, 2002), Tanacetum vulgare (Acha de la Cruz et al, 2008), Tripleurospermum caucasicum (Farjam et al, 2012) and Thuja occidentalis (Albert-Puleo, 1978).…”

Identification and Antibacterial Evaluation of Selected Jordanian Medicinal Plants

“…However, usage of these plant without awareness of their effect or dose toxicity, impose drawback in their medicinal benefits. Therefore, several studies were carried out on Jordanian medicinal plants, mainly on their antimicrobial and antioxidant activities [10][11][12] , phytochemistry [13][14] and ethnobotany [15][16][17] . Hence, the aims of this work are to analyze the chemical compositions and to evaluate the bioactivity of three selected Jordanian medicinal plants that are used as a folk medicine for various ailments Table 1.…”
