The extraction of traditional Chinese medicine extraction equipment of anthracene ring element
days extraction extraction research center for Chinese medicine extraction equipment for the extraction of anthracene ring element extraction process: distribution repeatedly with several kinds of solvent extraction, make free alkali soluble in organic solvent, and its sulfate or hydrochloric acid soluble in water. NCI and further development of extraction technology and simplified. With mixed solvent of impurities have greater selectivity. The crude extract with 30% acetone - water Toluene solvent washing especially effective. Because there is a lot of toxic anthracene in cells, so the separation process must have a special protective measures, require almost similar to protection of radioactive substances are used.
