[Study on refining process of Flos Chrysanthemi extract with macroporous resin].

ABSTRACT

OBJECTIVE: To determine the parameters of refining process of Flos Chrysanthemi extract with macroporous adsorption resin. METHODS: According to the chlorogenic acid and total flavonoids, to investigate the kind of macoroporous resin, the maximum quantity of physic liquor, and the type and quantity of elution solvent. Then combining with the retention rate of luteolin, to verify the parameters of the process. RESULTS: The maximum adsorption quantity of chlorogenic acid was 10.8 mg/g dry resin, and the elution solvent was 5-fold column volume of 80% alcohol; the purity of total flavonoids, chlorogenic acid and luteolin were 589.2%, 605.4%, 650.1%, respectively. CONCLUSION: The resin F can enrich the active components of Flos Chrysanthemi effectively.
