Neem Extracts

Neem extracts are very useful and widely used in the manufacturing of a wide range of medicines, cosmetic and pest control products. Neem extract contains the concentrated form of active or principle compounds found in neem. Since the quantities of active compounds are generally not very high in seed, leaves or other plant part, it is necessary to obtain these chemicals in concentrated form and use the concentrated extracts for the preparation of final products.

Method of Neem Extraction
Industrial scale neem extraction process make use of solvents such as alcohol, ether, and hydrocarbons instead of water. There are different methods of neem extraction. The choice of method and solvent will depend on the nature of chemical compound to be extracted.

Aqueous Neem Extraction : Powdered seeds, kernels or leaves are soaked overnight in water and the next morning the extract is strained through a piece of cloth; the desired volume of concentrated extract can then be used for desired purpose. Aqueous extract is generally rich in water soluble amino acids, pigments, soluble bitters and carbohydrates. Some manufacturers use the process of freeze drying the water-based neem extract producing a crystalline powder called "neem bitters" that is also water soluble.

Solvent Neem Extraction : Organic solvents such as alcohol, dimethyl sulfoxide and ethers are also used to manufacture high concentration extracts. In one of the simplest extraction processes, the pure solvent is continuously poured over the mass of material to be extracted. It is percolated through the material until the removal of desired components is complete. The choice of solvent and temperature and time determine the efficiency of extraction.
