As a result of chemical investigation on the ethanolic extract of fresh fruit coatings of Azadirachta indica A. Juss. (neem), twenty-seven compounds were identified in non-polar to less polar fractions which showed pesticidal activity determined by WHO method against Anopheles stephensi Liston. These identifications were basically made through GC-EIMS and were further supported by other spectro...

The present study was carried out to screen and evaluate antimicrobial activity of leaf extracts of Azadirachta indica A. Juss. Petroleum ether, dichloromethane, chloroform, ethanol and aqueous extract of leaves of A. indica were tested against selected Gram positive and Gram negative bacterial species. Phytochemical leaf extracts of A. indica exhibited significant anti-bacterial activity again...

The presence of endophytic fungal mycelia within healthy tissue is most commonly detected by long incubation of small pieces of surface-sterilized healthy tissue on agar plates and the emergence of their mycelia or spores. Thus, to understand their biology and distribution within the host, it is mandatory to use histological tools to locate the endophytic mycelia as well as spores in vivo withi...

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...

In the present study, aqueous extract of eight plants, namely Azadirachta indica A. Juss, Melia azedarach Linn., Lantana camara L. Moldenke., Cannabis sativa Linn., Nerium indicum Mill., Eucalyptus sp., Ricinus communis Linn. and Solanum nigrum Linn. were tested for antifeedant and toxic effects against Pieris brassicae (Linn.). The ethanol extract of four potential plants were further tested f...

Azadirachta indica had ample therapeutic action since many years. Hepatoprotective effect of methanolic and aqueous extracts of azadirachta indica leaves was evaluated using Male Wistar rats. Result indicate that the plant good potential to act as hepatoprotective agent.
