Effect of seasonal variations on the yield of essential oil and antioxidant of Achillea fragrantissima (Forssk) Sch. Bip

Abstract

Temperature stress is becoming the major concern for plant scientists worldwide due to climate change. Temperature stress has devastating effects on plant growth and metabolism. The aim of the study was to investigate the effect of climatic seasonal change on the yield and composition of essential oil of the plant, Achillea fragrantissima. The gas chromatography-mass spectrometry (GC-MS) used to analyze the essential oil collected during dry and wet seasons revealed it has 25 compounds. The major compounds were santolina alcohol (5.31), camphor (4.3), and cedrene (9.01) during winter months, while the percentages of α-cubebene (17.1%), spathulenol (1.54) and globulol (5.2) were highest during summer season. The analysis of essential oil in the two seasons revealed that there are different amounts and composition of essential oils. The antioxidant activity of the essential oil of the plant shows higher activity of IC 50 0.11±0.01g/L and Ec 50 0.25±0.02 g/L during winter than in summer. However, the reducing capacity of standard substances used (ascorbic acid and α-Tecopherol) were 0.033±0.001 and 0.93±0.07 g/L for DPPH and 0.091±0.002 and 0.026±0.002 g/L for FRAP method, respectively. These results showed that A. fragrantissima is a natural source of active compounds, and antioxidant properties, and the difference in chemical composition leads to changes in the antioxidant activity of the plant, which contributes to seasonal change.

Composition and fumigant protectant potential of Tunisian <em>Citrus aurantium </em>L. essential oils against <em>Rhyzopertha dominica </em>F.(Coleoptera: Bostrichidae)

“…Additionally, Moraes et al [13] reported that peels essential oils from Brazilan C. aurantium consist mainly for Limonene and myrcene with a percentage of 98% and 1.45%. These differences in the compositions of essential oils may be depended to different factor, for exemple, seasonal, maturational stage and pedoclimatic variation [14,15], also, the extraction method and the age of the trees can influence the quantity and the quality of the essential oils [16,17]. Thid study shows also the sensitivity of adults of Rhyzopertha dominica to the peels essential oils of C. aurantium.…”

In Vitro Analysis of Antimalarial Activity of Achillea fragrantissima (Forssk.) Sch.Bip Extracts Based on Beta-Hematin Formation

“…It also contains unsaturated amides and sesquiterpene lactones. 20,23 Notably, achillolide A, a sesquiterpene lactone present in A. fragrantissima , exhibits strong anti-inflammatory properties, acts as a scavenger of reactive oxygen species, as well as inhibits the formation of nitric oxide (NO). 24 A variety of water-soluble polyphenols were identified in water-alcohol extracts of A. fragrantissima's above-ground parts.…”
