It originated from Egypt, Ethiopia and India. Subsequently it was spread to Brazil, Thailand, Argentina and United States of America etc. The castor planted in China came from India and has a history of more than 1400 years. Castor has very high value in use: castor bean seeds can produce castor oil; castor leaves can raise silkworms; castor stems can be made into paper and medium density board etc. ; castor bean seeds, leaves, roots and stems can be used as natural medicine. Modern medical research shows that ricin is an important cancer-resisting substance. Castor meal is nutritious which is a good quality organic fertilizer and a high protein feed after detoxication. The oil content of castor bean seeds is about 50% with which other oil crops are unable to compare.The three main use of castor oil:First, high-grade lubricant: castor oil has special stability, it doesn’t solidify at -18℃ and doesn’t deteriorate and burn at500~600℃, so castor oil becomes the most important lubricant for aerospace, it is also good automobile brake-used oil.Second, important industrial chemicals: castor oil contains near 90% of ricinoleic acid, which makes castor oil becomes the important raw material of modern chemical. Almost all products made from petroleum can be made from castor oil, but many products made from castor oil are not able to be made from petroleum. There are no less than 3000 deep processed products of castor oil, nylon-11, sebacic acid and 12-hydroxy stearic acid etc. have been widely used in such High-tech industries as pharmaceuticals, aerospace, military, communication, machinofacture and fine chemistry etc.Third, the most promising biological energy: as continuous increasing scarcity of world petroleum resources, people pay more and more attention to energy utilization of castor. Castor will be the most promising biological energy because of its high unit area oil production, wide adaptability and because it doesn’t occupy fertile farmland which is good for growing grain crops and cotton. The main castor producer is India, China and Brazil, the total yield of these three countries is more than 80% of the world total production.The world castor planting area is more than 3 million hectares all year round a
