The chemical composition and antioxidant activities of wild and cultivated Laurus nobilis leaves and Foeniculum vulgare subsp. piperitum seeds were determined. Differences were found in the total phenolic content of fennel. GC-MS analysis of the non polar fractions showed a different composition between wild and cultivated plants. Cultivated laurel had a high content of terpenes such as linool, a a-terpinol, a a-terpinyl acetate, thymol, caryophyllene, aromandrene, selinene, farnesene, and cadinene, while wild laurel had a high content of eugenol and methyl eugenol, vitamin E, and sterols. The antioxidant potential of the extracts was determined using three complementary methods. Wild plants showed greater radical scavenging activity than the cultivated plants. The extracts also exhibited a significant antioxidant capacity also in the b b-carotene-linoleic acid test system. A high level of antioxidant activity was observed in wild laurel (IC 50 ‫1؍‬ m mg/ml). Significant antioxidant activity measured in bovine brain was observed in wild laurel.

Phenolic compounds were extracted from Mallotus philippinensis bark using methanol. Six fractions (I-VI) were separated from the extract on a Sephadex LH-20 column using ethanol and acetone-water as the mobile phases and were evaluated for their total antioxidant activity, antiradical activity against DPPH• (2,2-diphenyl-1-picrylhydrazyl radical), and reducing power. The total phenolics and tannin contents in the fractions were determined. The content of total phenolics in the fractions ranged from 54 mg/g (fraction I) to 927 mg/g (fraction VI). Condensed tannins were detected in fractions II-VI. Total antioxidant activity (TAA) of phenolic fractions of Mallotus philipinensis bark extract ranged from 0.58 mmol Trolox/g (fraction I) to 6.82 mmol Trolox/g (fraction IV). Fraction IV also showed the strongest antiradical activity against DPPH • and reducing power. Several phenolic constituents in the fractions were detected by RP-HPLC using a gradient solvent system with UV-DAD detection.

Yield and composition of the essential oil obtained by hydrodistillation from leaves of laurel coming from ten different sites in Tunisia were determined. From each locality, leaves were harvested during four different vegetative stages (October, production of seeds; January, dormancy; April, flowering; July, vegetative activity) to look for some correlation between composition and vegetative stage. All 40 essential oil samples produced similar GC profiles containing a total of 71 peaks. 60 Compounds were identified. 1,8-cineole was, in all samples, the main constituent among different compounds such as methyl eugenol, -terpinyl acetate, sabinene and linalool. All essential oils considered were characterized by a clear predominance of oxygenated compounds chiefly monoterpenes then phenylporpanoids and sesquiterpenes. The concentration of this class generally decreases during the period October -July; the values are in the range 67.5% -86.1%. The yields of essential oil ranged between 0.65 and 2.2% by weight. With only one exception, the higher production of essential oil was obtained during the vegetative period. A seasonal variation in the yield and composition of essential oil was revealed, while geographical variability was not pronounced and no chemotypes were observed among the samples of laurel leaf oil examined.
