| titleOfInvention | Method for determining total solanesol in tobaccos and tobacco products |
| abstract | The invention discloses a method for determining total solanesol in tobaccos and tobacco products. The method comprises the following steps of: 1, carrying out simultaneous supersonic extraction and saponification on tobacco solanesol, specifically, taking the tobaccos or the tobacco products and grinding the tobaccos or the tobacco products into tobacco powder; placing the tobacco powder into a centrifugal glass tube and adding an extraction solvent and a saponification agent respectively; simultaneously carrying out the supersonic extraction and the saponification on the tobacco solanesol; 2, washing and separating a tobacco solanesol extracting solution, specifically, cooling the extracting solution to a room temperature and adding a certain volume of water; completely vibrating and centrifuging; 3, taking 0.500mL of an upper-layer solution and diluting a flowing phase until the volume is 5.000mL; filtering the solution to a liquid chromatogram ampere bottle by using a 0.22-micron organic filtering membrane to be detected; and 4, carrying out liquid chromatogram determination on the obtained solution to be detected. According to the method disclosed by the invention, the extraction, the saponification and the separation are all finished in the centrifugal tube; the method has the advantages of small solvent dosage, simplicity in operation, cost saving, pollution reduction and improvement of working efficiency; the method is suitable for analyzing samples in a large batch, and the accuracy and the precision of determined results are high. |
