Abstract

India has about 45000 plant species; while medicinal properties have been assigned to several thousand. Apium graveolens (Celery) belonging to family Apiaceae, used as a decorative herb in India in general and more particular in Punjab and Uttar Pradesh. Celery ischolar_mains, leaves, stem, oils and seeds are used for the therapeutic purpose in treating and preventing many diseases. In the present study the effect of celery on cholesterol induced rats was studied. Ethanolic extract of celery leaves was orally administered by post treatment at the dose level of 500mg/kg of body weight for 7^th, 14^th, 28^th and 56^th days respectively. Administration of cholesterol induced rats resulted in increased total cholesterol, triglycerides, LDL, VLDL and decreased the HDL cholesterol. Administration of celery extract resulted in HDL cholesterol increase and decrease in the total cholesterol, triglycerides, LDL and VLDL in duration dependent manner. The above finding proved that 56th day treatment of ethanolic extract of celery was found to have more protective effect on lipid profiles in cholesterol induced rats. The results of the above studies are discussed in the light of recent literature.

Abstract

Molasses is a thick syrup produced as a byproduct of sugar industries. It is used in industries like food, beverages, lactic acid and acetic acid manufacturing units. For the present study, the effluent samples were collected from lactic acid manufacturing company using molasses as a raw material. The physico-chemical parameters such as colour, odour, pH, EC, salinity, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), hardness, bicarbonates, alkalinity, chloride, nitrites, calcium, sulphate, sodium, potassium, magnesium and total free sugars (glucose) of both the effluents (untreated and industry treated) were studied to ascertain the role of aquatic plants (Eichhornia crassipes, Pistia stratiotes, Ludwigia adscendens) in bioremediation of molasses effluent. Among the plants used in the study, Eichhornia seems to be best in treating the industrial waste. The efficiency of treatment of the molasses effluent by the plants was Eichhornia crassipes > Pistia stratiotes > Ludwigia adscendens.

Abstract

The II instar stage of Anopheles, Aedes and Culex mosquito larvae were treated with ethanolic extract of Lantana camara stem. The extract showed lethal effect on Anopheles, Aedes and Culex II-instar stage of mosquito larvae in different concentrations and mortality rate increased for every 24 hours continuously for 4 days. But it was remarkable to note that the mortality was maximum in 600 mg/100mL concentration of ethanolic extract of Lantana camara stem in 24 hours, which prompted to select the concentration.
