Abstract
Artemisia herba-alba (Compositae) is one of the most important medicinal plants. It is important to carry out this research with regard to the presence of different populations of a species in different regions and lack of sufficient information about these populations. This study was conducted to evaluate the quantity and quality of essential oils and some secondary metabolites of Artemisia herba-alba plant collected from Andimeshk County (Khuzestan Province) in two vegetative and reproductive phases. The results showed that the fresh plant sample had the highest percentage of essential oil (%0.96) in the reproductive phase. Also, the results of studies on secondary compounds of Artemisia herba-alba showed that flavonoid, total phenolic compounds, flavonol, anthocyanin and antioxidant activity in vegetative phase were 5.16 mg quercine/leaf dry weight g-1, 2,41 gallic acid mg/leaf dry weight g-1, 0.301 mg quercine/ leaf dry weight g-1, 0.089 mg /dry plant tissue g-1 and 0.26 nano acid ascorbic acid/g-1, respectively. Also, the secondary compounds studied of flavonoid, total phenolic compounds, flavonol, anthocyanin and antioxidant activity in the reproductive phase were 7.36 mg quercine/ leaf dry weight g-1, 1.95 mg gallic acid/dry leaf weight g-1, 0.28 mg quercine/ leaf dry weight g-1, 0.11 mg/ dry plant tissue g-1 and 0.21 nano-acid ascorbic/g-1, respectively. GC and GC-MC analyzes were used to evaluate the essence and quality of essential oils. In general, investigations have identified 19 compounds that showed a large difference in the composition of plant and dry samples in vegetative and reproductive phases. The dominant components of the essential oil were cis chrysanthenol (21.80 to 18.28%), chrysanthenum (10.06 to 6.17%), subinen (9.34 to 7.01%), trans-verinil acetate (5.91 to 4.78%), pipertinone (4.66 to 4.11%), terpinen-4-ol (4.38 to 3.73%), 6-ccomfonon (4.57 to 2.96%), 1 , 8-Cineol (2.82 to 1.85%) and Alpha-Tojan (1.93 to 1.36%). Due to the biochemical and physiological morphological characteristics of a plant that follows two factors of genetics and environment, it can be expected that the plants in different regions have different secondary compounds
