Essential oil compositions, antibacterial and antioxidant activities of various populations of Artemisia chamaemelifolia at two phenological stages

Variation in Essential Oil Composition, Bioactive Compounds, Anatomical and Antioxidant Activity of Achillea aucheri, an Endemic Species of Iran, at Different Phenological Stages

“…Similarly, the results were also in agreement with those of a previous research by Sardrodi et al, [39] in which the yield of the essential oil of A. aucheri collected at different growing altitudes ranged from 0.68 to 0.95 % (v/w). Similar results was also obtained in A. biebersteinii, [22] Artemisia chamaemelifolia, [10] Rosmarinus officinalis, [40] Ocimum ciliatum, [36] Origanum majorana [41] and Thymus maroccanus, [42] which revealed high yields of essential oil at the flowering stage. The changes of the oil quantity and quality can highly be affected by the plant growing time [43] and the germplasm.…”

“…[4][5][6][7] A. aucheri has also been applied as antispasmodic, anti-inflammatory operative, diuretic and diaphoretic agents, as well as the treatment agents of hemorrhage, pneumonia, rheumatic pain and wounds from ancient times. [3] Several studies have been reported that the amount of secondary metabolites and the antioxidant capacity of plants can be highly affected by both intrinsic and extrinsic factors such as climatic conditions and growing site, [8] harvesting time, [9] genetic background [10] and phenological stages. [11] The essential oils (volatile oils) were considered as the most important components among other volatile secondary metabolites in medicinal plants.…”

“…[32] For example, oil globules are found within the membranes of secretory cell of rhizome in Zingiber officinale, [33] peltate gland on leaves of Lippia scaberrima, [34] and secretory cavity in peel section of Citrus, which are responsible for the biosynthesis of essential oils. [35] The effect of phenological stages on essential oil composition and other bioactive compounds has been reported in many medicinal plants including Ocimum ciliatum, [36] Rosmarinus officinalis, [37] Artemisia chamaemelifolia, [10] Salvia aegyptiaca [38] and Foeniculum vulgare. [11] There are limited researches on the effect of phenological stages in Achillea species including A. biebersteinii.…”

Chemical ​Composition and in ​Vitro ​Antibacterial ​Effect of Ziziphora clinopodioides ​Essential ​Oil

“…In order to determine the minimum bactericidal concentration of the essential oil that reduces 99.99% of population bacteria, 20µl of each well without any invisible growth was cultured on BHI agar at 37°C for 24h. 13,14 Agar disk diffusion assay The antibacterial activity of leaves of Z. clinopodioides essential oil was also evaluated by agar disk diffusion method according to Bajalan et al, 15 with some modification. For this purpose, 100µl of inoculum of bacteria (1×10 8 CFU/ml) were poured on BHI agar and cultured by surface method and sterile cotton swabs.…”

Ameliorative Effects of Qurs-E-Afsanteen on Gentamicin Induced Hepatotoxicity and Oxidative Stress in Rabbits

“…It has antibacterial, antifungal, anthelmintic, antimalarial and antioxidant activities (Amrollahi et al, 2014). It shows hepatoprotective activity by scavenging free radicals and lipid peroxidation inhibiting mechanism (Pirbalouti et al, 2013). Valeriana officinalis (Sumbal-uttayyab) commonly known as valerian and belongs to Valerianaceae family.…”
