This research focuses on understanding biosorption process and developing a cost effective technology for treatement of heavy metals-contaminated domastic water. A new biosorbent has been prepared by crushing of neem leaves. The experiments were designed according to Taguchi’s (L16) orthogonal array to optimize experimental runs. In order to assess the biosorption behavior of neem leaves satisf...

Diabetes Mellitus is affecting people of all age groups worldwide. Many synthetic medicines available for type 2 diabetes mellitus in the market. However, there is a strong requirement for the development of better anti-diabetes compounds sourced especially from natural sources like medicinal plants. The extracts from the leaves of neem (Azadirachta indica) is traditionally known to have anti-d...

Induced resistance is an important component of disease-resistance response of plants, and is accompanied by increased capability for activating defense responses upon pathogen ingress or elicitor treatment. Aqueous leaf extract of neem (Azadirachta indica Juss.) provided the control of Alternaria leaf spot pathogen (Alternaria sesami) of sesame (Sesamum indicum L: Syn. S. orientale L). Treatme...

s: Background and Objectives: This in vitro study was designed to evaluate and compare the antimicrobial effects of extracts of Neem sticks, Tulsi leaves and Triphala against Streptococcus Mutans and Lactobacillus Acidophilus.Materials and Methods: Sterile solutions of 10% & 25% concentrations were prepared from Neem, Tulsi and Triphala extracts. After growing on culture plates micro-organisms ...

The efficacy of different extracts of neem leaf on seed borne fungi Aspergillus, Rhizopus and chemical characterization of the neem leaf extracts were studied in vitro on the culture medium. The growth of both the fungal species was inhibited significantly (p<0.01) and controlled with both alcoholic and water extract of all ages and of the concentrations used. The alcoholic extracts of neem lea...

We have previously shown that the flowers of neem tree (Azadirachta indica A. Juss, family Meliaceae), Thai variety, strongly induced the activity of glutathione S-transferase (GST) while resulting in a significant reduction in the activities of some cytochrome P(450)-dependent monooxygenases in rat liver, and possess cancer chemopreventive potential against chemically-induced mammary gland and...

The impact of three different doses of botanical insecticide derived from the syringa tree, Melia azedarach and the neem tree, Azadirachta indica was tested on the behaviour of the diamondback moth, Plutella xylostella (Linnaeus). Both botanical insecticides had a significant impact on larval behaviour. At higher doses the extracts showed feeding deterrent activity, with larvae preferring the u...

OBJECTIVE The aim of this study was to investigate the antioxidant activity of the aqueous extracts of leaves of Siamese neem tree (Azadirachta indica A. Juss var. siamensis Valeton) from several extracting and drying methods using 2,2-diphenyl-1-picrylhydrazyl (DPPH)-scavenging assay. MATERIALS AND METHODS The leaves of Siamese neem tree were extracted using percolation, decoction, maceratio...

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,...

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)...
