20080214847 | Process for the Separation of Paclitaxel and Cephalomannin - Paclitaxel is separated from a mixture containing cephalomannin by column chromatography on silica gel using a solvent mixture containing methyl isobutyl ketone and a less polar solvent as the mobile phase. The less polar solvent can be a (C | 09-04-2008 |
20080262223 | Isolation of Galanthamine From Biological Material - The subject matter of present invention relates to the process for isolation and purification of galanthamine and its derivatives produced by numerous plants. | 10-23-2008 |
20080269479 | Process for Isolation of Macrolide Compounds - Although macrolide compounds are insoluble in water, surprisingly high part of the product was found in the liquid phase of the fermentation broth. Therefore, processing the entire fermentation broth, i.e. the suspension obtained by cultivation of a microorganism producing the required macrolide compound, is highly advisable. This invention teaches a method of processing the entire fermentation broth using cheap and environmentally acceptable solvents. | 10-30-2008 |
20080312447 | Process for Isolation of Crystalline Tacrolimus - The invention is a simple process for separation of tacrolimus and its analogues, ascomycin and tsucubamycin B and preparation of enough pure crystalline tacrolimus. The process takes advantage of surprising properties of tacrolimus and involves extraction, purification and crystallization to produce purified crystalline tacrolimus. | 12-18-2008 |
20090216031 | Process for the isolation of paclitaxel - Paclitaxel is isolated by a process including normal phase chromatography using a polyamide stationary phase and a mixture containing a dialkyl ketone and a less polar solvent as a mobile phase. Suitable dialkyl ketones include acetone or methyl isobutyl ketone. Suitable less polar co-solvents include a (C | 08-27-2009 |
