| titleOfInvention | High-purity separation process for emodin |
| abstract | The invention discloses an emodin high-purity separation process, which relates to the field of emodin separation processes and aims to solve the problem that in the prior art, a used reagent is a toxic solvent and poses threats to both human bodies and the environment; the emodin can be separated from the mixture by using ethyl acetate for extraction, and the ethyl acetate is non-toxic and has no pungent smell, so that the health of personnel and the environmental safety are protected; the water-soluble impurities can be removed by using distilled water for elution, so that the purity of the product is improved; the emodin crude extract obtained by filtering is subjected to chromatographic column chromatography, elution, reduced pressure distillation and recrystallization, and the eluent is prepared from alcohol, so that the elution effect is good, the emodin yield is improved, the emodin crude extract is pollution-free and easy to separate, and the personnel health and the environmental safety are further protected. |
