Abstract:
OBJECTIVETo establish the technology for extraction of ginkgolides from Ginkgo Biloba with alcohol-water.
METHODThe parameters such as alcohol concentration, pH of extracting solution, ratio of dosage liquor, temperature and time, the extraction of ginkgolides from G. biloba was investigated, and its parameters were optimized.
RESULTThe optimized parameters were alcohol concentration 30%, extracting temperature 50 degrees C, extracting time 2 h, pH 5 solid-liquid ratio 1:15.
CONCLUSIONThis method has the merits of low cost and simple operation.
