Considering the interest in natural products for cosmetic, perfumery, food and pharmacological industry, the deeper knowledge of the potentiality of different aromatic plants can give results of economic importance. In our work, the essential oils of fourteen species were evaluated for their quali- quantitative composition and biological activity. The species analysed are: basil (Ocimum basilicum L.), beebalm (Monarda didyma L.), pennyroyal (Mentha pulegium L.), spearmint (Mentha spicata L.), headed savory (Thymus capitatus Hoffm.et Link), calamint (Calamintha nepeta L.), winter savory (Satureja montana L.), savory (Satureja cuneifolia Ten.), thymbra (Thymbra sintenisii Bornm. et Aznav. ssp. isaurica P.H. Davis), a cultivated rosemary (Rosmarinus officinalis L) and four wild rosemaries harvested in different Italian locations: Elba Island (Tuscany), Sicily, Abruzzo and Calabria. The oils, obtained by steam-distillation of fresh aerial part of the plants harvested at full flowering stage, were characterized by GC-MS, tested for antimicrobial property by determining the minimal inhibitory concentration (MIC) and for the antioxidant activity by B-carotene bleaching test. Each species was characterized by a peculiar qualiquantitative composition and all the oils contained compounds with established biological activity. Headed savory exerted the highest antimicrobial control also at low concentrations. Basil and rosemary from Elba Island evidenced a great antioxidant capability comparable to that of α-tocopherol used as reference antioxidant agent.10aAntimicrobial Activity10aAntioxidant activity10aGC-MS1 aStefanini, I1 aPiccaglia, R1 aMarotti, M1 aBiavati, B  uhttp://www.scopus.com/scopus/inward/record.url?eid=2-s2.0-33846036924&partnerID=40&rel=R6.5.001875nas a2200277   4500008004100000245011300041210006900154260012000223300001400343490000600357520092200363653001801285653001001303653001401313653001301327653002301340653001001363653001101373653002201384100002001406700001801426700001901444700002101463700001601484856009701500       1994                        eng d00aSeasonal variation in essential oil yield and composition from naturalized Thymus vulgaris L. in New Zealand0 aSeasonal variation in essential oil yield and composition from n  aAffiliation: Redbank Research Station, New Zealand Inst. Crop Food Res. Ltd, PO Box 42, Clyde, New Zealandc1994///  a347 - 3520 v93 aThe seasonal variation in essential oil yield and composition from naturalized Thymus vulgaris L, in Central Otago, New Zealand, is reported. Essential oil yield (l/ha), from replicated, pilot-scale distillations, was influenced by both the held production of herb and the essential oil content of the herb. The oil yield peaked at 22.8 l/ha in December, after flowering had finished. Essential oil composition also varied significantly during the 13-month sampling period. Levels of the phenolic components, thymol and carvacrol, peaked at a total of 37% after flowering in summer (December and January). p-Cymene was an important component of Central Otago thyme oils and ranged from 40% to 50% in winter and early spring (May to October), declining to 21% in January. To maximize yields and phenol content of the oil, naturalized thyme in Central Otago should be harvested after flowering has finished in December.10aEssential oil10aGC-MS10aLamiaceae10aP-cymene10aSeasonal variation10aThyme10aThymol10aThymus vulgaris L1 aMcGimpsey, J, A1 aDouglas, M, H1 aVanKlink, J, W1 aBeauregard, D, A1 aPerry, N, B  uhttp://www.scopus.com/scopus/inward/record.url?eid=2-s2.0-0028578069&partnerID=40&rel=R6.5.002181nas a2200241   4500008004100000245012800041210007000169260013000239300001400369490000700383520126200390653001901652653000701671653001001678653001401688653004901702100002101751700001701772700001901789700001801808700001601826856009701842       2001                        eng d00aEssential oil composition of Thymus lotocephallus G.

The oils were isolated by hydrodistillation and distillation-extraction and analysed by GC and GC-MS. The oil isolated from the flowers was obtained in a yield of 0.9%, whereas those isolated from the leaves during flowering and vegetative phases showed lower yields, 0.7% and 0.2% (v/w), respectively. The oils isolated from both the flowers and the leaves were dominated by the oxygen-containing monoterpenes (57-64%). The monoterpene hydrocarbons (11-22%) and the oxygen-containing sesquiterpenes (7-14%) were the two other main fractions of these oils. 1,8-Cineole (10-19%), linalyl acetate (6-14%) and linalol (4-12%) were the main components of all the oils studied. Intermedeol (2-4%), beta -caryophyllene oxide (2-3%) and viridiflorol (1-3%) were the main components of the oxygen-containing sesquiterpene fraction. The diterpene abietatriene was present in trace amounts (<0.05%) in all the oils. Depending on the plant part studied and on the isolation procedure used, these oils can be characterized either by 1,8-cineole/linalol/linalyl acetate or 1,8-cineole type.

V., Facultc2003///  a165 - 1690 v893 aEssential oils of seven Moroccan Labiatae were chemically analysed by GC-MS and evaluated for their in vitro antifungal activity against Botrytis cinerea. Among them, Origanum compactum and Thymus glandulosus greatly inhibited the growth of the mycelium. The inhibition of Botrytis cinerea was 100% for both oils at 100ppm, while the IC50s were 35.1 and 79.2ppm, respectively. Mentha pulegium exhibited moderate activity at 250ppm since the inhibition of the mycelial growth was 58.5% and the IC50 was 233.5ppm. The main constituents of the studied oils were also examined. Thymol and carvacrol that are the two main constituents of Thymus glandulosus and Origanum compactum exhibited the strongest antifungal activity with 100% of inhibition at 100ppm, respectively. © 2003 Elsevier Ireland Ltd.
