The tomato (Lycopersicon spp.) productivity is severely reduced by attack of several insects and microorganisms. It is economically one of the most important crops that has been extensively cultivated in the Americas. Therefore, assays were performed in the greenhouse and the laboratory to evaluate the possible interaction between resistant tomato genotypes and plant extracts on the control of ...

Dietary excess of lipids causes substantial health disorders like hyperlipemia, obesity and cardiovascular problems. Use of lipase and α-glucosidase inhibitors in combination is considered to be the ideal therapy for obesity control. Anti-obesity activity of natural products is usually assessed by inhibition of pancreatic lipase activity by the preparations. We have reported earlier that some k...

Vermicompost singly and in binary combination with different biopesticide were used in agricultural field to control the infestation of nematode (Meloidogyne incognita) and high yield of cauliflower (Brassica oleracea) crop. Mixing of binary combination of vermicompost with neem oil (94%) in the soil caused significant reduction in M. incognita. The combination of garlic extract with different ...

BACKGROUND/AIM Protein tyrosine phosphatase 1B (PTP 1B) and dipeptidyl peptidase IV (DPP IV) have been identified as one of the drug targets for the treatment of Type-2 diabetes. This study was designed to screen for PTP 1B and DPP-IV inhibitors from some Nigerian medicinal plants. MATERIALS AND METHODS PTP 1B and DPP-IV drug discovery kits from Enzo Life Sciences were used to investigate in ...

The antifungal activity of eight different medicinal plants namely Aloe vera, Ocimum sanctum, Cenetella asiatica, Piper betle, Calotropis gigantea, Vitex negundo, Ocimum basilicum and Azadirachta indica were tested against plant pathogenic fungus (red rot disease causing agent) Colletotrichum falcatum by agar well –diffusion method. The plants leaves were extracted with various solvents like ch...

The in vitro toxicity of neem seed oil (Azadirachta indica A. Juss, family: Meliaceae, Dogon yaro in Hausa language in Nigeria) was tested against the larvae of a one-host tick, Boophilus decoloratus (family: Ixodidae or hard tick, commonly known as blue tick) parasitic mainly to cattle generally found in savannas of tropical equatorial Africa. The 20, 40, 60, 80 and 100% concentrations of neem...

In recent years, there is a development of vaginal contraceptives incorporating potent spermicides. Many compounds with different pharmacological activity have been evaluated in vitro for their spermicidal activity. Drugs such as surfaceactive agents (synthetic and natural), ionophores, antiliquefying agents, antimicrobial agents and miscellaneous agents such as gossypol, Azadirachta indica, va...

Neem oil was obtained from the seeds of the neem tree, Azadirachta indica, exploiting a manually operating bridge press, and used to prepare toilet soap. The chemical properties of the soap were 63.75 %, 0.24 %, 0.06, 1.15 %, 12.6 % and 10.4 as its total fatty matter, total alkali, free caustic alkali, percentage chloride (% Cl), % moisture and pH respectively. Due to the phytoconstituents in n...

In the present scenario of environmental consciousness, the new quality requirements not only emphasize on the intrinsic functionality and long service life of the product but also a production process that is environment-friendly. Therefore, research on environment-friendly antimicrobial agents based on natural products for textile application is gaining worldwide interest. This paper reports ...

Ammodesmidae are represented in western Africa by two species of a single genus, Ammodesmus Cook, 1896 (= Cenchrodesmus Cook, 1896, syn. n.). The type-species Ammodesmus granum Cook, 1896 (= Cenchrodesmus volutus Cook, 1896, syn. n.) is redescribed, based on neotype selection, as well as on additional samples, often containing numerous specimens, from Liberia, Guinea and the Ivory Coast. A new ...
