This component will cause an increase in the permeability of the cell membrane, thereby facilitating the entry of other active compounds especially: 4-terpineol. [24] Several authors have shown that in addition to the major compounds, minor ones such 4-terpineol (0.64%) significantly contribute to the activities of EO by synergistic action.
The peaks in the chromatogram belong to the main compounds which are more than 1% of the EO chemical composition: (1) [alpha]-pinene, (2) [beta]- pinene, (3) sabinene, (4) limonene, (5) eucalyptol, (6) [alpha]-copaene, (7) camphor, (8) linalool, (9) 4-terpineol, (10) alloaromadendrene, (11) trans- verbenol, (12) [alpha]-terpineol, (13) borneol, (14) germacrene D, (15) [delta]-cadinene, (16) spathulanol, (17) sesquisabinene hydrate, (18) (-)- caryophyllene oxide, (19) nerolidol, (20) cis-caryophyllene, (21) [alpha]-cedrene, (22) 8-hydroxylinalool, (23) spathulenol, (24) [alpha]-muurolol, (25) [alpha]- cadinol, (26) epiglobulol, and (27) juniper camphor (the peak numbering given here is not in accordance with peak numbers in Table 3).
Upon GC/MS analysis essential oil contained thirty compounds eluted on a DB-1-1022 column such as 1R-a-Pinene, b-Pinene, D-Limonene, b-Phellandrene, b-Terpinyl acetate, T-Terpinene, p-Cymene, Dehydro-p-cymene, cis-b-Terpineol, Trans-p-Metha-2,8-dienal, 4-Terpineol, Trans-dihydrocarvone, a-Terpineol, D-Carvone, Carvone, Cis-p-Menth-1-en-3-ol, 2,3-Epoxycarene, L-cis-Sabinol, p-Cymen-8-ol, cis-Carveol, Estragole, 2-Pinen-4-one, 2-Allyl-4-methyl phenol, O-tert-butyl Phenol, Thymol, Carvacrol, Elemicin, Myristicin, Apiol, Methoxyeugenol and Limonene-6-ol, pivalate (Table 5).

alternifolia were identified; principal compounds were oxygenated monoterpenes being 4-terpineol the principal one (39.9%).
Thus the presence of [alpha]-pinene, [alpha]-terpinene, [gamma]-terpinene, terpinolene, [beta]-terpineol, a-terpineol (one the major compounds in fruit extract), 4-terpineol, isoborneol, [gamma]-cadinene (the major compound in leaf extract), [alpha]-cadinene, cadina-1, 4-diene and [sigma]-cadinene may contribute to the diuretic and antiseptic action of the leaf and fruit extracts of the Egyptian J.
-- Only two monoterpenes were identified in the condensate from the heat exchanger: x-terpineol (0.66 mg/[kg.sub.ODwood]) and 4-terpineol (0.32 mg/[kg.sub.ODwood]) A total of 1,193 L of water were condensed in the heat exchanger.
