Chemical composition of the essential oil of unripe galls of Pistacia atlantica Desf. from Algeria

Abstract

The essential oils obtained by hydrodistillation of unripe galls of Pistacia atlantica and collected from both male and female trees yielded 0.53% and 0.46% v/w, respectively. The essential oils were analyzed by GC and GC-MS showing the occurrence of a new ����3-carene rich chemotype showing a content of 75.34%. The second is the well known chemotype ����-pinene/����-pinene, which is rich in ����-pinene (59.01%) and ����-pinene (13.26%).
