Chemical composition, antibacterial and antifungal activities of flowerhead and root essential oils of Santolina chamaecyparissus L., growing wild in Tunisia

Abstract

The antimicrobial properties of essential oil from various species have not been investigated enough in the previous studies dealing with the biological activities of medicinal plants. In Tunisia, L. (Asteraceae) is the only species recorded and is used as vermifuge and emmenagogue. The chemical composition, antibacterial and antifungal properties of essential oils from the flowerheads and roots of spontaneous growing in Tunisia and the chemical composition which leads to the Tunisian chemotype are investigated here for the first time. Essential oils isolated by hydro distillation from flowerheads and roots of were analyzed by GC and GC/MS. Two methods served for antimicrobial assays of the essential oils: diffusion in a solid medium and micro-well dilution assay. Antifungal tests were carried out by the agar incorporation method. Sixty-seven constituents were identified from the essential oil of the flowerhead. The major constituents were: 1,8-cineole and-eudesmol. Two non identified compounds were present at the highest concentration in root oil. Flowerhead oil was characterized by high contents in monoterpenes and sesquiterpenes oxygenated compounds. The flowerhead essential oil demonstrated potent of antibacterial properties against ATCC and ATCC, with MIC of 0.625 μg/ml. These findings demonstrate that the flowerhead essential oils of have excellent antibacterial properties and for this reason they could contribute to decrease the problem of microbial resistance to antibiotics.

Biocidal Potential and Chemical Composition of Industrial Essential Oils from Hyssopus officinalis, Lavandula × intermedia var. Super, and Santolina chamaecyparissus

“…chamaecyparissus are 1,8‐cineole (11.2%) and spathulenol (7.6%) . However, the hydrodistilled oil of this species shows an enormous chemical variability, and some oils are rich in artemisia ketone (27 – 38%) and β ‐phellandrene (9 – 22%) [ ][ ] or in camphor (31.1%) …”

Chemical composition, antibacterial and antioxidant activities of essential oils from flowers, leaves and aerial parts of Tunisian Dittrichia Viscosa

“…The Mediterranean and semi-arid climate of this country favors the growth of various types of wild plants whose valorization is under-exploited. Some of them, such as Artemisia campestris L., Lavandula stoechas L., Origanum glandulosum, Pelargonium graveolens ., are known for their anti-diabetic effects in traditional medicine (1) while others have been recognized as having anti-bacterial effects (Santolina chamaecyparissus L.) (2) or herbicide effects (Pinus nigra) (3) . The valorization of all these natural resources is mainly based on the extraction of volatile molecules, called "essential oils" whose composition determines their usefulness for medicinal, cosmetic or food applications.…”

Determination of Essential Oil Composition, Phenolic Content, and Antioxidant, Antibacterial and Antifungal Activities of Marigold (Calendula Officinalis L.) Cultivated In Algeria

“…Among of them , αcadinol, showed selective toxicity against human colon adenocarcinoma cells (Sylvestre et al, 2006) (He et al, 1997). Otherwise, it was reported that the essential oils extracted from other medicinal plants containing αpinene, p-cymene , α-copaene and δ-cadinene as volatile components have a potential antimicrobial and antifungal activities (Bel Hadj Salah-Fatnassi et al, 2017).…”
