Opis:
Production of alternative energy sources from eco-friendly raw materials is supposed to be the most challenging job among researchers and academicians in the present world. Biodiesel has been considered as most useful green energy sources which is produced from Crude Neem (Azadirachta indica) oil (CNO) in the present study. The main advantages of CNO is that it is non-edible and is obtained abundantly in nature from neem seed. Initially, after bleaching of CNO, it is transesterified with methanol in the presence of non-specific enzyme catalyst Novozyme 40013 (Candida antarctica) maintaining certain reaction conditions. The parameters of the transesterification reaction have been identified as 8:1 molar ratio of methanol to CNO, 60 °C temperature in the presence of 6% enzyme Novozyme 40013 and 600 rpm of mixing intensity for 9 hrs of reaction duration. The product obtained, after completion of reaction, has been estimated of 91.24% biodiesel along with minor amounts of triacylglycerol (TAG), diacylglycerol (DAG) and monoacylglycerol (MAG). Finally, the physico-chemical properties of CNO biodiesel have been analysed and it showed good conformity with diesel fuel and biodiesel standard.

Opis:
Fossil fuel resources are decreasing daily while biodiesel fuels are attracting increasing attention worldwide as blending components or direct replacements for diesel fuel in vehicle engines. 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 and saponification value. Hence the neem seed oil tested in this current study could be the potential sources of raw material for biodiesel production.

Opis:
Azadirachtins are known as phagorepellent natural products from seeds of the neem tree Azadirachta indica A. Juss (Meliaceae), which impede the development of larval insects and sterilize adults. The labors of the past three decades ultimatively lead to a chemical structure, which has been unanimously but independently elaborated by German, British and American authors. This structure is in force ever since 1985/87 and was ultimately confirmed by Veitch & al. in Ley’s group in Cambridge, England, through total synthesis. Its 25th birthday is presently being celebrated. Marrangin (=Azadirachtin L) was discovered in Gießen and chemically identified by Kalinowski and colleagues. It occurs in seeds of the marrango tree, Azadirachta excelsa (Jack) Jacobs. In some insect species but also in mites like Tetranychus urticae, its biological activity is significantly superior to azadirachtin A. The value of these biorational compounds, with their very low vertebrate toxicity, and their low toxicity today is globally recognized. Quite recently, azadirachtin and analogues gain acceptance in veterinary and human medicine.
