| titleOfInvention | Method for extraction and purification of quinine from italian ryegrass |
| abstract | The present invention relates to a method for extracting and purifying quinine from an Italian rice glaze. More specifically, the present invention relates to a method for extracting and purifying quinine from an Italian rice glaze, comprising the steps of: adding an ethanol solution adjusted to pH 1 to 2 to an Italian rice glaze; Dissolving the ethanol extract in water, adjusting the pH to 9 to 10, and extracting with chloroform to obtain a chloroform extract; And fractionating the chloroform extract with silica gel chromatography using chloroform and methanol as a mobile phase to obtain a quinine-containing fraction. The present invention also relates to a method for extracting and purifying quinine from Italian ryegrass. According to the present invention, quinine can be obtained from Italian rice grains, which are feed crops. Therefore, it can be a great help to solve the problem of relying on imports of quinine or its raw materials, and it is expected that it will contribute to raising the income of the farm household by providing a new use of Italian rice. |
