SCREENING FOR BIOLOGICAL ACTIVITIES OF ESSENTIALS OIL PROFILES (GC-FID) AND ETHANOLIC EXTRACTS FROM PINUS BRUTIA (TEN) AND PINUS CANARIENSIS (C. SMITH)

Interest in natural products derived from plants and their biological potentialities has increased as a result of environmental concerns. In this study, the phytochemical characterisation of essential oils and ethanolic extracts originated from Pinus brutia (Ten) and Pinus canariensis (C. Smith) needles along with their antimicrobial activities were achieved. The essential oils from both pine species were characterized using GC-FID and GC-MS and the chemical profiles included mainly trans-caryophyllene (49.82%), δ-cadinene (32.50%) and isoterpinolene (2.99%). The essential oils of both Pinus canariensis and Pinus brutia exhibited notable antimicrobial activities against the clinical gram-negative bacteria Enterobacter cloacae and Escherchia coli. The biological activities of both studied essential oils recommended their use in the formulation of environmentally-friendly and biocompatible pharmaceutical drugs.
