Essential Oil Composition and Antimicrobial Activity of Artemisia herba– alba Asso Grown in Algeria

Abstract

In the recent decades, antimicrobial plant products have gained special interest because of the resistance to antibiotics that some microorganisms have acquired. Aromatic and medicinal plants are an important source of bioactive molecules, especially in volatile extracts, that are considered among the most important antimicrobial agents present in these plants. Volatile components of Artemisia herba-alba Asso essential oil obtained by hydrodistillation growing in Algeria (Djelfacityof south Algeria) were investigated by GC/FID and GC-MS. The major components were found to be camphor (39.5%), chrysanthenone (10.38%), 1,8-cineole (8.6%), α-thujone (7.03%), Borneol (3.35%) and bornyl acetate (2.52%). The essential oil has been tested for antimicrobial activity against Gram-negative and Gram-positive bacteria. Inhibition of growth was tested by the agar diffusion method. The Minimal Inhibitory Concentration (MIC) was determined by the method of agar dilution.

Chemical Composition, Antioxidant, Anti-Tyrosinase, Anti-Cholinesterase and Cytotoxic Activities of Essential Oils of Six Algerian Plants

“…Moreover, its combination with paclitaxel showed a synergistic effect on non-small-cell lung cancer (NSCLC), thus confirming the importance of the evaluation of the combined use of EOs rich in compounds with reported in vitro anti-proliferative activity in cancer chemotherapy [67]. Compositional differences with published literature also emerged in the EO of A. herba-alba; while the accession of the present study was mainly composed of oxygenated sesquiterpenes, specimens from Algeria [34,37] and Morocco [68] were reported as predominantly composed of oxygenated monoterpenes. J. phoenicea, instead, showed the same α-pinene chemotype as reported for five specimens from Eastern Algeria [28] and one from the Boulmane region of Morocco [69].…”

“…The genus Artemisia (Asteraceae) contains approximately 400 species, widely distributed in the Mediterranean region, Northern Africa, Western Asia, Southwestern Europe and Arabian Peninsula [34]. Artemisia herba-alba is a greenish-silver perennial herb belonging to the Asteraceae family, with many popular names: in Algeria it is known as the white wormwood, in Arabic as "Chih", and in France as "Armoise blanche" [35][36][37]. In traditional medicine, the plant has been used to treat many ailments including colds, coughing, bronchitis, intestinal disturbances, diarrhea, neuralgias arterial hypertension and/or diabetes [38][39][40].…”

“…In traditional medicine, the plant has been used to treat many ailments including colds, coughing, bronchitis, intestinal disturbances, diarrhea, neuralgias arterial hypertension and/or diabetes [38][39][40]. For A. herba-alba EO, numerous biologic and pharmacological properties are reported in the literature, such as antimicrobial, antioxidant, antidiabetic, antileishmanial, anthelmintic and antispasmodic [36,37,[41][42][43][44][45]. Artemisia campestris L. is a perennial herb, usually known as field wormwood.…”

Antimicrobial Activity of Different Essential Oils against Aspergillus flavus and Klebsiella pneumoniae Isolated from Respiratory Tract

“…Essential oils and other extracts of plants have evoked interest as sources of natural products concerning their potential uses as alternative remedies for the treatment of many infectious diseases (Nor et al, 2016). Essential oils possess antibacterial, antifungal, antiviral insecticidal and antioxidant properties against microorganisms (Lakehal et al, 2016). Essential oil exhibited maximum inhibitory activity against respiratory disease causing microbes like Klebsiella pneumoniae, Streptococcus pneumoniae, Haemophilus influenzae, and P. aeruginosa (Skocibu et al, 2004).…”

Enhancing blood donor skin disinfection using natural oils

“…Essential oils (EOs) have been documented by various studies as having antibacterial properties . This activity has mostly been attributed to oxygenated terpenoid compounds (e.g., phenolic terpenes and alcohols) found in EOs, such as linalool, eucalyptol (1,8‐cineole), and thymol.…”
