| Abstract: | The paper based on a research of the red pigment of Celosia Cristata L of Xinjiang,attempts to exploit the best precipitator,acid,alkali,Ph value and usage of the precipitator.It proves the six-times ethanol without water precipitated the pigment with two per cent ZnCl2 as precipitator,with ammonia as the solution of alkali and with Citric acid as the solution of acid,the best distilling effect and the output ration of the red pigment of 12.3% can be obtained about three percent. |
| Keywords: | Celosia cristata L Red pigment metal ion the solution of acid the solution of alkali precipitation |
