Patent ID: 7632524

Claim:
A lipophilic extract from family Euphorbaciae, species Croton made by a process comprising: combining latex from family Euphorbaciae, species croton with an organic solvent to produce a combination; agitating the combination; settling the combination into distinct phases to resolve a layer substantially comprised of hydrophilic constituents and an organic layer substantially comprised of lipophilic constituents; separating the organic layer from the layer substantially comprised of hydrophilic constituents; adding a drying agent to the organic layer to further precipitate any remaining hydrophilic constituents; evaporating the organic solvent from the organic layer to resolve the lipophilic constituents; and filtering the organic layer to retain the lipophilic constituents to thereby yield the extract; wherein the wavelength absorbency of the extract in a range of 390 nm and 430 nm is reduced by 500% compared to the wavelength absorbency of unextracted latex from family Euphorbaciae, species croton.
