Scientific Name Paris polyphylla Smith
Family Liliaceae
Used Part Tuber
Distribution Area A glabrous erect herb, 30-45 cm. high, with thick, creeping rootstock found in the temperate Himalayas at altitudes of 1,500-3,000m. from Simla to Bhutan, and in Lushai and Aka hills.
Common Uses . The rhizome possesses anthelmintic properties; its powder taken with hot water is used as a tonic. The plants of P. polyphylla var. chinensis and var. yunnanensis are credited with sedative and analgesic properties and form one of the constituents of the Chinese medicine `Chonglou'..
Chemical Constituent A glycoside, pennogenin, has been isolated from the seeds of P. polyphylla var. yunnanensis.
There is nothing to stop biodiesel making an immediate impact in reducing the world's dependence on fossil fuels that contribute to global warming. Using biodiesel requires no major changes to either existing diesel engines or to the current distribution infrastructure of storage tanks and petrol stations that delivers diesel fuel to consumers.
Petroleum diesel produces high levels of carbon dioxide (CO2), a greenhouse gas that contributes significantly to global warming. But burning biodiesel produces only a marginal increase in CO2 emissions, because the crops from which it is produced capture CO2 as they grow.
The state of Rajasthan is situated between 23°3’N and 30°12’ N latitude and 69°30’ and 78°17’ E longitude. The total land area of the state is about 3,42,239 km2, out of which about 1,96,150 km2 is arid and rest is semi-arid. This arid and semi-arid wasteland is rich in biodiversity. During present investigation studies were conducted on characterization of bio-energy resources in the semi arid region of Rajasthan.
230 plants species were characterized and out of them 60 plant species were selected for dry matter production, 11 plants were characterized for non-edible oil production and 13 plants were characterized for hydrocarbon production. With the growing demand for fuel wood these plants possibly use as bio-energy sources in their natural habitat.

INTRODUCTION
In 2002, fossil fuels supplied 86 percent of
the energy consumed in the United States. We
also imported over half of the petroleum we used
and we project that our dependency will continue
to grow. Since the U.S. economy is so closely
tied with petroleum products and oil imports,
small changes in oil prices or disruptions in oil
supplies can have an enormous impact on the
American (and for that matter the entire Global)
economy. We understand that we will always
rely on fossil fuels. But, we also understand that
value of developing technologies using renewable
energy sources, including biomass, and the
important role it can play in energy security,
economic growth, and the environment.
The central focus of the current DOE
Biomass Program is an integrated approach to the
