Methods for the extraction and purification of poly-unsaturated fatty acid(PUFA)from viscerai oil of three fresh-water fish (bream,grass carp and silver carp)were studied- It was suggested that the medicinal quality standard of PUFA could be laid down by referring to the quality standard of Acidum Morrhuicum.

Objective: To study the hypoglycemic action of Herb Tab(HT) on hyperglycemia mice and normal animals as well as the effect on their serum insulin. Methods: The model of hyperglycemia mice was established by injecting Alloxan intravenously; the extractum prepared from HT was introgastrically administrated into testee; blood glucose was detected with enzymologic method and serum insulin was examined by competitive radioimmunoassay (RIA); all datas were processed through statistical analysis of t test. Results: The extractum of HT administrated introgastrically for 14d markedly reduced the blood glucose of alloxan induced hyperglycemia mice ( P
