In the present work Clevenger apparatus is applied to obtain essential oil from Syzygium aromaticum L. Clevenger extraction represents an environmentally method for oil herb extraction as it employs water as solvent during the distillation process. Essential oils are highly valued. They are traditionally used in medicines and health remedies. The purpose of the present work is to obtain essential oil from clove plant and subsequently indentify the chemical composition by means of spectroscopic techniques. Essential oil samples were analyzed by spectroscopic techniques FTIR spectroscopy and UV-Vis. spectrophotometer. Both techniques indicated presence of eugenol as main chemical component in the oil of clove in excellent agreement with reported literature data.

Approximately two-third ( 229 km²) of the lake lies in Montenegro and one third(142 km²) lies in Albania. The lake has a particular water regime causing water level fluctuations. This changes the shore line generating a unique landscape type with wetlands and numerous aquatic habitats. Skadar Lake is known as a hight biodiversity ecosystem. According to the autors the submergedand emersed macrophysics are the most characteristic features of the littoral in Skadar Lake. The most important association of the vegetation type are Najadetum marinae, Potameum perfoliati, Potametum lucem, Potameto-Najadetum, Myriophyllo-Nupharetum lutei, Trapetum natantis, Phragmitetum australis, Thyphaetum latifolia. Submersed macrophytes are more developed in the eastern part of the lake which go as for as 3 m deep such P.perfoliatum, P.lucens, Vallisneria spirals, Najas marina, Najas minor, Ranunculus trichophyllus.

It is a considerable producer of herbs including common sage, raspberry leaf, thyme, oregano, and chamomile. The mountainous relief and Mediterranean climate are the main factors for having such an ecosystem diversity and biodiversity. Extraction of essential oil from M. recutica L. is carried out using a Soxhlet technique. Carbon dioxide (CO 2 ) is used a solvent for the extraction under near critical conditions, since it is physiologically harmless, environmentally safe and it can be easily removed from products. Additionally, hexane is used as well for the Soxhlet extraction and the yield of the obtained extract is compared with yield of the extract obtained with liquid CO 2 . FTIR analysis indicated presence of matricine, dicycloether and α-bisabolol as organic components present in the essential oil of M. recutica L.

The pyrite structure can be sufficiently destabilized locally in the
