egard to isoflav<strong>on</strong>e c<strong>on</strong>centrati<strong>on</strong> and it variability within the clover species, some accessi<strong>on</strong>s of<br />
T. medium and T. pratense can be c<strong>on</strong>sidered a highly promising source of phytoestrogens.<br />

<str<strong>on</strong>g>Abstract</str<strong>on</strong>g>: As part of the development of plant resources, we are interested in the chemical study<br />
of essential oils of Mentha aquatica that is widely used in Algerian traditi<strong>on</strong>al medicine. Essential<br />
oils extracted from this plant obtained by hydrodistillati<strong>on</strong> with a Clevenger type apparatus for a<br />
period of three hours. The extracti<strong>on</strong> produces yellowish essential oils with a very str<strong>on</strong>g odor.<br />
Chemical analysis of the essential oils is achieved by gas chromatography coupled with mass<br />
spectrometry (GC / MS). The major compound in essential oil of M. aquatica is linalyl Acetate<br />
(26.109%) and other c<strong>on</strong>stituents such as α-Pinene (22.708%), Linalool (13.755%), in additi<strong>on</strong><br />
morphological studies witch is realized manually show tow different types of glandular trichomes<br />
<strong>on</strong> leaves and stems and lacunar parenchyma in stem secti<strong>on</strong>.<br />

<str<strong>on</strong>g>Abstract</str<strong>on</strong>g>: Spices lavish several phytochemical molecules to diet and play c<strong>on</strong>sequently a<br />
significant role in the preventi<strong>on</strong> of chr<strong>on</strong>ic diseases. The aim of our work is to proporti<strong>on</strong> these<br />
molecules also said antioxidants in three spices: black pepper, cinnam<strong>on</strong> and ginger in the two<br />
forms: whole spices and powders. Samples: black pepper, cinnam<strong>on</strong> and ginger in the two quoted<br />
marketed forms. Solvents of extracti<strong>on</strong>: Boiling water, ethanol 50%, ethanol 70%, hexane. UV-<br />
Visible spectrophotometer was used for the proporti<strong>on</strong>ing of the following antioxidants:<br />
carotenoids, phenolic compounds, flav<strong>on</strong>oids, anthocyanins and proanthocyanidins. Procedure:<br />
three extracti<strong>on</strong>s were carried out: the first <strong>on</strong>e to extract carotenoids, the sec<strong>on</strong>d <strong>on</strong>e to extract<br />
the total phenolic compounds, the flav<strong>on</strong>oids, the proanthocyanidins and the third <strong>on</strong>e to extract<br />
the anthocyanins. Variati<strong>on</strong>s of antioxidants c<strong>on</strong>tents were raised according to spice and type of<br />
solvent. According to the results of proporti<strong>on</strong>ing obtained, cinnam<strong>on</strong> (whole spice and powder)<br />
showed remarkable c<strong>on</strong>tents for the majority of antioxidants: example of the phenolic compounds:<br />
whole spice: 4,40±0,43g/100g, powder spice: 6,82±0,98g/100g for boiling water, 1,49±0,03g/100g<br />
and 29,19±1,30g/100g for the ethanol 50%, 9,94±0,39g/100g and 38,47±0,49g/100g for the<br />
ethanol 70%, except the anthocyanins where no c<strong>on</strong>tent is revealed and carotenoids where the<br />
values are of 0,15±0,06g/100g and 3,05±0,09g/100g respectively for whole spice and powder. The<br />
results of the antioxidant activity (reducing power) c<strong>on</strong>firmed it richness compared to ginger and<br />
black pepper. It is highly advised to incorporate these spices in the dishes to profit from the<br />
benefits which they can bring, while respecting the amounts to be introduced.<br />
Key words: Antioxidant activity, antioxidants, solvents, spices.<br />
