The study was designed to investigate analgesic and antipyretic activities of petroleum ether and alcohol extracts of Centratherum anthelminticum (L) Kuntze (family: Asteraceae) seeds (100 and 200 mg/kg, p.o.) in brewer's yeast-induced fever model in rats, acetic acid-induced writhing and Eddy's hot plate methods in mice. Both petroleum ether and alcohol extracts showed significant decrease in ...
Pathways of initial oxidation of n-alkanes were examined in two strains of Cladosporium resinae. Cells grow on dodecane and hexadecane and their primary alcohol and monoic acid derivatives. The homologous aldehydes do not support growth but are oxidized by intact cells and by cell-free preparations. Hexane and its derivatives support little or no growth, but cell extracts oxidize hexane, hexano...
This study was designed in order to correlate the flavonoid and lipoidal matters content of Spinach roots and flowers to their hypolipidemic potential. The total flavonoid content was measured via complexation with aluminum chloride while determination of fatty acids methyl esters and unsaponifiable matters contents in both organs was performed using GC/MS. In an in vitro study, the crude etha...

INTRODUCTION Stinging nettle (Urtica dioicd L.) is one of the most valuable plants used in phytotherapy. The herbal raw material is a herb (Urticae herba), leaves (Urticae folium), roots (Urticae radix) and seeds (Urticae semina). This plant is a good source of vitamins, minerals, fibre, protein and biologically active compounds with antioxidant properties. The literature provides limited infor...
Ethanol formation during glucose fermentation is a relatively common activity of microorganisms; a few species, including Leuconostoc mesenterodes, produce ethanol as a major fermentation end product. The significant results from experiments with various species on this subject are: (1) at least three different metabolic pathways are available for anaerobic conversion of glucose to ethanol (Kos...
ETHNOPHARMACOLOGICAL RELEVANCE The genus Echinacea is a popular herbal immunomodulator. Recent reports indicate that Echinacea products inhibit nitric oxide (NO) production in activated macrophages. AIM OF THE STUDY In the present study we determined the inhibitory effects of alcohol extracts and individual fractions of alcohol extracts of Echinacea on NO production, and explored the mechanis...
BACKGROUND Identification of wheat sensitization by a skin prick test (SPT) is essential for children with wheat-induced anaphylaxis, since oral food challenge can cause serious adverse effects. Wheat allergens are both water/salt and alcohol soluble. The preparation of wheat extract for SPT containing both water/salt and alcohol soluble allergen is needed. OBJECTIVE To determine if a wheat e...
Objective: The antiulcer activity of various extracts of Hibiscus rosa sinensis leaves was evaluated in pyloric ligation induced gastric ulcer in albino rats. Method: The leaves extracts were prepared by cold maceration process with petroleum ether, alcohol and water separately. Results: Oral administration of aqueous and alcohol extracts (200 and 400 mg/kg) of Hibiscus rosa sinensis leaves wer...
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...
