    Reinvestigation Of Essential Oil Content Of Thapsia Garganica Grown In The East Of Algeria
    (University of Eloued جامعة الوادي, 2011-07-01) Ladjel, S.; Zellagui, A .; Gherraf, N.
    Thapsia garganica is a very famous medicinal plant known especially for its therapeutic effects such as diuretic, emetic and purgative. A resin is extracted with alcohol from the bark of the root. The plant has been considered specific in treating pain, though caution is advised since it is poisonous to some mammals. The plant is also strongly rubefacient, producing blisters and intense itching. In the present study, we have undertaken a Reinvestigation of essential oil content of this widely used plant because of its important bioactive effect to heal many ailments.

    The Synthesis Of (5-hydroxy-5-(1-methoxypropan-2-yl) -4-methylfuran-2(5h)-one, 5-(1-methoxypropan-2-yl) -4-methylfuran-2(5h)-one) And Biological Activity
    (University of Eloued جامعة الوادي, 2011-07-01) Gherraf, N.; Tamma, N.
    Butenolides are a class of lactones with a four carbon heterocyclic ring structure. They are sometimes considered as oxidized derivatives of furan. The simplest butenolide is 2-furanone, which is a common component of larger natural products and is sometimes referred to as simply "butenolide". A common biochemically important butenolide is ascorbic acid (vitamin C). The butenolide and their analogues represent a wide range of the natural compounds of medical and biological importance. In the last decades, a great number of compounds of various structures, in general from Alkylidene butenolide were isolated and showed biological activities. In this work we have studied the reactivity of some alkylidene butenolide and carried out their antibacterial activity.
