Patent number: 5900367Abstract: The present invention relates to a rapid and simple method for mass production of taxol from the cell culture of Taxus genus plant with a high purity and recovery. The method for mass production of taxol from Taxus genus plant of the present invention, comprises the steps of: (i) organic solvent extraction of biomass from Taxus genus plant to obtain a crude extract; (ii) synthetic adsorbent treatment of the crude extract and filtration to give filtrate; (iii) addition of hexane to the filtrate to precipitate crude taxol; (iv) fractional precipitation of the crude taxol in a mixture of alcohol and water and vacuum drying the precipitate to obtain taxol powder; and, (v) high performance liquid chromatography of the taxol powder. According to the method of the present invention, taxol of over 99% purity can be simply obtained from Taxus genus plant with a high recovery of over 90%.Type: GrantFiled: May 28, 1996Date of Patent: May 4, 1999Assignee: Samyang Genex Co., Ltd.Inventors: Seung-Suh Hong, Bong-Kyu Song, Jin-Hyun Kim, Chang-Bae Lim, Hyun-Soo Lee, Kwang-Wook Kim, In-Seon Kang, Hung-Bok Park
