| titleOfInvention | Method for extracting high-purity verbascoside from campsis plant flowers |
| abstract | The invention belongs to the technical field of medicines, and particularly relates to a method for extracting and preparing high-purity verbascoside from campsis plant flowers. The extraction process comprises two steps of extraction and two steps of column chromatography, wherein the extraction process comprises the steps of removing impurities by ethyl acetate extraction, preparing acteoside fluid extract by ethanol water solution extraction, preparing crude extract of the acteoside by macroporous adsorption resin column chromatography, and preparing high-purity acteoside by reversed phase silica gel column chromatography, and finally obtaining the powder of the acteoside with the purity of more than 98%. The method fully utilizes the campsis plant medicinal material resources to extract and prepare the verbascoside, expands the sources and has rich medicine sources; the method adopts two-step extraction and two-step column passing method for the first time, optimizes and improves the extraction and preparation method of acteoside, and has simple operation and low cost; in the operation, only two organic reagents of ethanol and ethyl acetate are used, and toxic reagents such as methanol and acetone are not used, so that the method is non-toxic, harmless, green and environment-friendly; the verbascoside has high yield and purity, is easy to popularize and is worthy of recommendation. |
