Azadirachta indica leaves indicated the presence of active principles with proven antioxidants, antiinflammatory, immunomodulatory, free radical scavenging and healing properties. In the present study we evaluated the healing effects of 50% ethanol extract of dried leaves of Azadirachta indica on trinitrobenzene sulfonic acid-induced colitis in rats. Azadirachta indica extract (500 mg/kg) was a...

A 28-day feeding trial was conducted to evaluate the effects of dietary inclusion of Neem (Azadirachta indica) leaf meal on the haematological and serum biochemical indices of starter broilers. The Neem leaves used in the experiment were manually harvested, air-dried and milled to become Neem leaf meal. The Neem leaf meal was included in broiler starter diets at 0, 2.5, 5.0, 7.5 and 10% levels,...

Azadirachta indica , an Indian medicinal plant, has been studied for its role in diabetes and its effect on lipid profile. This study was conducted to elucidate whether treatment of Azadirachta indica leaf extract after streptozotocin (STZ) induced diabetes has anti-hyperglycemic and anti-dyslipidaemic action or not. The experiment involved four groups of rat; one group was control group, secon...

Background: In Nigeria decoctions and aqueous extract of Azadirachta indica A. juss (AI), are commonly used in the treatment of malaria. Some women have been observed consuming aqueous extract of AI during pregnancy and lactation because of the folkloric belief that it is potentially harmless. Objectives: There is a paucity of data on the effects of consumption of AI during pregnancy and lactat...

Feeding trials were conducted for 28days to evaluate the nutritional value of Neem (Azadirachta indica) leaf meal on the performance and economics of deep litter managed finisher broiler production. The neem leaves were harvested, air dried and milled to become neem leaf meal. It was included in the broiler finisher diets at 0,2.5,5.0,7.5 and 10% levels respectively. One hundred and fifty (150)...

The National Research Institutes’ 1992 report on neem anticipated that continuing research into the components of a tree known in India as a ―village pharmacy‖ would demonstrate useful cures for various ailments, but it’s unlikely that even the most optimistic researcher could have predicted the potentially life-saving treatments being identified now for preventing or treating multiple types ca...

Morphological changes of a toxigenic isolate of Aspergillus parasiticus cultured in the presence of aqueous leaf and seed extracts obtained from neem, Azadirachta indica A. Juss (syn. Melia azadirachta L.), a potent inhibitor of aflatoxin biosynthesis, was studied. Mycelial samples obtained from A. parasiticus cultures exposed to an effective concentration of the leaf and seed extracts (50% v/v...

The objective of this study was to optimise the extraction conditions for phenolic compounds from neem (Azadirachta indica) leaves using response surface methodology (RSM). A central composite rotatable design (CCRD) was applied to determine the effects of acetone concentration (%), extraction time (mins), and extraction temperature (oC) on total phenolic content (TPC) from neem (Azadirachta in...

Escherichia coli O157:H7 (EcO157) shed in cattle manure can survive for extended periods of time and intervention strategies to control this pathogen at the source are critical as produce crops are often grown in proximity to animal raising operations. This study evaluated whether neem (Azadirachta indica), known for its antimicrobial and insecticidal properties, can be used to amend manure to ...

The nematicidal activities of ammonium sulfate, chicken litter and chitin, alone or in combination with neem (Azadirachta indica) extracts were tested against Meloidogyne javanica. Soil application of these amendments or the neem extracts alone did not reduce the root galling index of tomato plants or did so only slightly, but application of the amendments in combination with the neem extracts ...
