Latest Patents
Gary T. Marshall holds a patent for the "Purification of 12-O-tetradecanoylphorbol-13-acetate, phorbol, and 4.alpha.-phorbol." This innovative process utilizes droplet counter-current chromatography to isolate and purify 12-O-tetradecanoylphorbol-13-acetate (TPA), phorbol, and the diastereoisomer 4.alpha.-phorbol from croton oil. The method employs a carefully equilibrated mixture of hexane, diethylether, n-propanol, ethanol, and water to create the stationary and mobile phases. The upper layer serves as the stationary phase, while the bottom layer acts as the mobile phase. The TPA and phorbol isomers are obtained in exceptionally high purity through further treatment with liquid column chromatography and thin-layer chromatography.
