Chemical composition,mineral contents and antioxidant activity of fruits of pistacia lentiscus L. From eastern morocco

The aim of this work is the valorization of pistacia lentiscus l. by chemical characterization,mineral composition,and study of the antioxidant activity of essential oil. the hydrodistillation of the fruits of this tree provides essential oil (0.56 %). 3-carene (54.10 %) and a- pinene (7.64 %) were found to be the major components. the essential oils of leaves and fruits were subjected to screening for their possible antioxidant activities by using 2,2-diphenyl-1-picrylhydrazyl (dpph). the results showed that the essential oils of leaves and fruits of p.lentiscus collected from saidia (eastern morocco) were found to be less efficient in radical scavenging with an ic50 values of 23.79 μl/ml and 29.63 μl/ml respectively,by comparison with the essential oil of leaves from taforalt(eastern morocco) (ic50=12,8 μl/ml). mineral contents of fruits were determined by inductively coupled plasma atomic emission spectrometry (icp-aes). the highest levels of k and cu were found in fruits of p.lentiscus from saidia (eastern morocco).
