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.
