ABSTRACT

OBJECTIVE:

To optimize the extraction technology of thrombolytic components predominantly as corilagin from Phyllanthus urinaria.

METHODS:

The extraction technology was optimized by orthogonal experiment with solvent amount,extracting time and extracting times as factors,and with the comprehensive score of the yield of extract and corilagin content as indexe.The impurity-removing efficacy by centrifugation,acid/base method or ethanol precipitation was evaluated.

RESULTS:

The optimal extraction technology was as follows using 8-fold volume of 30% ethanol as solvent for reflux extraction of 3 times(2 hours/ time).The best impurity-removing efficacy was achieved when 90% ethanol was used for precipitation.

CONCLUSION:

The extraction technology is simple and stable with high yield of active components,and it provides theoretic basis for the industrial production.
