Volatile Composition and Biological Activity of Jordanian Commercial Samples of L. Fruits.

The present paper reports the GC-HS-SPME analysis of volatile emission and GC-MS analysis of chemical composition of essential oil of fruits of eight different samples of L. fruits ("sumac" folk name), collected from Jordanian agricultural field and the local market. The analyses show an important variability among the Sumac samples probably due to the origin, cultivation, harvesting period, drying, and conservation of the plant material.
