Phenolic extracts of canola (Brassica napuse L.) contains substances that inhibited the germination and seedling growth of soybean (Glycin max L.). These compounds also affect activity of some enzymes. Hear, we investigated the allelopathic effects of various canola plant parts on soybean germination, seedling growth, and biochemical aspects. Phenolic extract of canola shoot (including leaf,...

purpose: in this study the inhibitory effect of eucalyptus extracts as a natural and herbal antibacterial substance was evaluated against pseudomonas aeruginosa strains (8821m and atcc27853). material and methods: the mic (minimal inhibitory concentration) of alcoholic and aquatic extracts of eucalyptus was determined using the tube and agar dilution methods. the growth rate of pseudomonas aer...

Plants are a potential source of natural antioxidants. Antioxidants protect from the potentially damaging oxidative stress, which is a result of an imbalance between the formation of ROS (Reactive oxygen species) and the body antioxidant defense. The present study was directed to investigate the antioxidant activity of methanolic extract of different plant parts of Cocculus hirsutus. The antiox...

Healthy Albino Rats (Wister variety) of either sex are reared feeding on pulses, gram and bread. After acclimatization these are divided into one normal-control and three experimental groups. Alcoholic hepatitis is induced in two of the experimental groups by oral administration of 30% ethanol for eight weeks. Oral administration of water-extract of Psidium guajava leaves is done to one non-alc...

Crude extracts from a medicinal Tunisian plant, Pergularia tomentosa L., were the investigated natural material. Butanolic extract of roots analyzed with IR spectra revealed the presence of hydroxyl, alcoholic, and carboxylic groups and sugars units. Analysis of some secondary metabolites, total phenolic, flavonoids, flavonols, and procyanidins, was performed using different solvents following ...

the whole plant, pergularia daemia (family: asclepediaceae), was extracted with 50% alcohol and a fresh batch of the plant material was successively extracted with petroleum ether, ethyl acetate and n-butanol to determine its diuretic activity. the diuretic activity of the different extracts at a dose of 400 mg/kg was assessed orally in rats with furosemide as a standard drug using lipschitzs t...
