The invention herein describes a procedure for organically extracting the lipophilic components from plants of the Family Euphorbaciae, specifically but not limited to the genus Croton. The extraction (CGO 110), is deplete of the normal proanthocyanidin content found in the parent material, yet retains its pharmacocological abilities and unlike the parent material, is selectively cytotoxic to cancer cells. The depletion of the proanthocyanidin components makes the product more amenable to preparations for the benefit of ameliorating both human and animal disease.

The invention discloses a tissue culture and rapid propagation method of Aleurites moluccana. The Aleurites moluccana is a Euphorbiaceae Aleurites woody oil plant. Currently, the Aleurites moluccana is mainly propagated wildly and naturally, propagation and seedling-raising with the tissue culture and rapid propagation method are rarely reported. The Aleurites moluccana is an often cross-pollinated plant, differences between wild seedlings are large, and propagation of seedlings with seeds is adverse to keeping of excellent properties such as the high oil content of excellent seed trees. In order to satisfy the huge demand of energy forest forestation for Aleurites moluccana seedlings, Aleurites moluccana stem segments with axillary buds are used as explants, in-vitro replantation plants of the Aleurites moluccana are obtained through processes of explant sterilization, induction culture, subculture, rooting culture, acclimatization and transplant and the like, a tissue culture and rapid propagation technical system for the Aleurites moluccana is established, and the method has the important significance for promotion of rapid development of the biomass energy industry.
