First report on identification of essential oil of Parietaria officinalis L., from Constantine (North-East of Algeria)

Abstract

In this study we were interested (consider avoiding this as it is ambiguous at this level.) in the study of the composition of the essential oil of parietaria officinalis L. harvested in the region of Constantine, (north-east of Algeria) which has thusfar never been studied. The essential oil obtained by hydrodistillation showed a yield of 0.15% ± 0.03. The analysis of this essential oil was made by GC-MS. The (3Z) hexenol chemotype was identified with a percentage of 53.23%. Several other compounds have been identified as trans geraniol (7.97%), eugenol (3.97%), (3Z) hexenyl acetate (3.53%), linalool with a rate of 3.23% and myrtenol with a content of 2.27%.
