Abstract:
OBJECTIVE To optimize the extraction technology of total flavonoids from pomelo peel by combining surfactant with microwave technology.
METHODS As an indicator of total flavonoids, orthogonal test was used to study the extraction conditions to extract flavonoids from pomelo peel.
RESULTS Optimum condition for extraction of pomelo peel was as follows: mass percentage of 2% lauryl sulfosuccinate disodium(AK-201) for the extraction solvent, microwave power 160 W, extracted twice for 1 min each time and the solid to liquid ratio was 1∶40. Using this technology, the extraction yield increased by 6.36% as compared with that using microwave technology alone.
CONCLUSION This extraction process is steady, feasible and reproducible which can be used for extraction of total flavonoids from pomelo peel.
