As the stock of fossil fuels diminishing throughout the world and demands for energy based comforts and mobility ever increasing, so there is a need to increase biodiesel production. Bio diesel is an alternative diesel fuel prepared from renewable resources and is most popular as an alternative energy sources because it is non toxic and biodegradable . India has great potential for production of biodiesel from non-edible oil seeds. From about 100 varieties of oil seeds, only 10-12 varieties have been tapped so far. The promising non-edible sources in India are Madhuca Indica (Mahua) ,Jatropha curcas(Ratan Jyot), Pongamia pinnata (Karanja) and Melia azadirachta (Neem). This review paper assesses and integrates the biological, chemical and genetic attributes of the plant and describes about the different tree borne oilseeds in India, Extraction of oil from tree borne oilseeds , properties ,composition and future potential of bio diesel If the developed process is scaled up to commercial levels then excellent business opportunity will be offered by the biodiesel and it could be a major step towards the creation of an eco-friendly transportation fuel that is relatively clean on combustion and provides farmers with substantial income.
