[The extraction and identification of total flavanone from longan pericarp].
OBJECTIVE
In order to make use of the resources of total flavanone in pericarp of longan.


METHODS
The flavonids were extracted with ethanol. Used spectrophotometry to check the flavanone.


RESULTS
The total flavanone in the pericarp was 1.101 mg/ml and the rate of recovery was 99.98%.


CONCLUSIONS
The extraction and purifying methods in this experiment can get the outcome and the purity of the flavanone very high. This method is a purely physical process and has not any pollution. It is an ideal way to extract the flavanone of longan skin.
