Larvicidal effect of neem (Azadirachta indica) and karanja (Pongamia glabra) oil cakes (individuals and combination) was studied against mosquito species. Both the oil cakes showed larvicidal activity against the mosquito species tested. The combination of neem and karanja oil cakes in equal proportion proved to have better effect than the individual treatments. The combination of the two oil c...

Neem oil is obtained from the seeds of the tree Azadirachta indica. Its chemical composition is very complex, being rich in terpenoids and limonoids, as well as volatile sulphur modified compounds. This work focused on the evaluation of a component of the whole Neem oil obtained by methanolic extraction and defined as MEX. Cytotoxicity was assessed on two different cell populations: a stabilize...

An experiment was conducted to determine the effect of some indigenous plant extracts on the germination of wheat seeds. Six locally available indigenous plants namely. Bazna (Zanthoxylum rhetsa Roxb.), Ghora-neem (Melia sempervirens L.), Hijal (Bartingtonia acutangula L.), Karanja (Pongamia pinnata L.), Mahogoni (Swietenia mahagoni L.) and -Neem (Azadirachta indica A. Juss.) were evaluated. Le...

Department of Biotechnology, Gulbarga University, Gulbarga 585106, Karnataka, India. [email protected] and [email protected] ABSTRACT: In this experiment the seed oils of 30 Neem (Azadirachta indica. A. juss) biotypes were screened and evaluated for their physio-chemical parameters for oil content, biodiesel yield, density, viscosity, iodine value , free fatty acid, saponification ...

The present study reveals that the selected plants would exert several benefits by virtue of their antioxidant activity and could be harnessed as antimicrobial, anti-inflammatory and anti-corrosive agents. The aqueous and Ethanol crude extract of Neem, Hibiscus leaves and the mixture of both leaves' extract were screened for their free radical scavenging properties. Free radical scavenging acti...

OBJECTIVE To examine the acaricidal effects of the essential oil of Cymbopogon citratus leaf extract (lemongrass) and ethanolic Azadirachta indica leaf extract (neem) against house dust mites Dermatophagoides farinae (D. farinae) and Dermatophagoides pteronyssinus (D. pteronyssinus). METHODS Twenty-five adults mites were placed onto treated filter paper that is soaked with plant extract and b...

An aqueous plant extract from Azadirachta indica and its chromatographic fraction F1 (neem extract) exerted immunomodulating and antimetastatic activities in BALB/ c-mice. Regular subcutaneous administration of neem extract yielded significantly increased spleen weight and significant enhancement of peritoneal macrophage activity in the chemiluminescence assay, and activation marker CD-44 expre...

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 ...

INTRODUCTION Debridement and disinfection of the root canal is a crucial step in the success of endodontic treatment. Several antimicrobial agents alone or in combination are used to achieve this. The objective of this in vitro study was to assess the antimicrobial efficacy of neem (Azadirachta indica) extract against Enterococcus faecalis. MATERIALS AND METHODS Neem leaf extract, 2% chlorhex...

Azadirachta indica (Neem) seed oil brings about a significant diminution in spermatozoan motility and density. It leads to reduction of fertility rate in rats and rabbits. The body weight of the animals remain unaffected but the weights of reproductive oranges declined. Reduction of cauda epididymal protein, sialic acid, acid phosphatase and seminal vesicular fructose concentration in rats and ...
