| titleOfInvention | Method for extracting and purifying bisbenzylisoquinolines |
| abstract | A method for purifying extracted crude d-tetrandrine by dissolving the crude d-tetrandrine powder in ethanol, treating the solution with a decolorizing agent, filtering, reducing the filtered solution under heat and vacuum, cooling the solution, filtering it and drying the filtered cake to yield substantially pure d-tetrandrine. |
