“…1). The content of total phenols and flavonoids, observed in our study, were higher than that reported for samples from the southern part of Tunisia [29,30] or for other Artemisia species such as A. annua, A. arborescens, A. ludoviciana, A. oleandica, A. princeps and A. stelleriana, [31] and Artemisia vulgaris. [32] The contents and the composition of total phenolic and flavonoid of A. herba-alba extracts varied according to plant origin, the solvent of extraction and the analytical method used.…”

Total phenols, flavonoids, flavonols, and flavanols of the methanolic extract of the aerial part of Artemisia herba-alba were determined. The extract was analyzed by liquid chromatography with photodiode array coupled with electrospray ionisation mass spectrometry and allowed to identify of 10 phenolic compounds. Apigenin-6-C-glycosyl flavonoids and caffeoylquinic acids were identified. Chlorogenic acid and 1,4 dicaffeoylquinic acid being the major constituents. The essential oil obtained by hydrodistillation was analyzed by gas chromatography-mass spectrometry. Twenty-three compounds, representing 97.8% of the total oil, were identified. The most abundant components were βthujone (41.9%), α-thujone (18.4%), and camphor (13.2%). Methanolic extract and essential oil exhibited a considerable antioxidant activity as evaluated by 2,2-diphenyl-pycrilhydrazil hydrate scavenging activity, reducing power, β-carotene bleaching test, and chelating ability. The methanolic extract was found to be more efficient, while the essential oil exhibited the highest acetylcholinesterase inhibitory activity. Analysis of the antibacterial activity showed that A. herba-alba methanolic extract and essential oil are efficient against gram positive and gram negative bacteria.

“…It seems that foliage from shrubs that grow in semiarid regions contains K as lower levels from costal and this not accordance with [31]. In this study the contents of Na are lower than those reported in (Abdullah, 2013) study, which it was (0.48 ppm) but they are lower than result found in [32] study (7.95 ppm).…”

This study was designed to find out effect of random construction on morphological and chemical composition characteristics of Juniperus and Pistacia. Both species of the plant were collected from two different areas in AL-Gabal AL-Akhder. First area was exposed to pollution from random construction that causing dust-contaminated cement to the plants, while the second area was not contaminated. The plants which are affected by building materials and grazing have smaller wrinkled yellow to grey leaves, while the fruits look smaller in size compared to same species from clean area. Our results shown that the both species of plants (Juniperus phoenicea and Pistacia lentiscus) were get difference in amount of mineral and the phenolic contents. The levels K and Cu were significantly decreased in J. phoenicea 1 (from polluted area) compared to J. phoenicea 2 (from clean area), while the level of Ca significantly increased. Rest levels of minerals were found similar in J. phoenicea 1 and J. phoenicea 2. In another species level of Na, Fe and Ni were decreased significantly in polluted species (P. lentiscus 1) compared to clean species (P.lentiscus 2), while the levels of K and Ca was significantly increased in P. lentiscus 1 which collected from polluted area. Levels of alkaloids, coumarins, essential oil, flavonoids, glycosides, phenolic compounds, saponins, sterols (triterpens) and tannins were found have similar pattern when compared J. phoenicea 1 with P. lentiscus 1 and J. phoenicea 2 with P. lentiscus 2. These results from Juniperus and Pistacia species might reflected the deteriorate effects of construction dust air pollutants, both species recommend their using as bio indicators as well as folk medicine.

“…DPPH is a stable nitrogen-centered free radical, the color of which changes from violet to yellow upon Facciola (1990) reduction by either the process of hydrogen-or electron donation (Dehpour et al, 2009). The procedure adopted by Wong et al (2006) and modified by Akrout et al (2012) was used. Different concentrations of extracts (0.125 to 5 mg/ml) and standard [ascorbic acid (20 to 100 µg/ml) (Merck Co. (Germany)) were prepared (MeE for methanol extract, and AqE for distilled water extract).…”
