Deals with the influence of enzymolysis over the extraction and content anaysis offlavones in Hawthorn, The pectin in pulp decomposed bypectolase completely,and then extracted by ethanol andpurified by polycaprolactam,flavones produced colour withaluminium-nitrate that was quantitated by measurement of theabsorbance at 510nm. The result shows that: the content offlavones in dried pulp of Hawthorn is between 70%~75%,it shows striking difference with the result gained from thecurrent method.The stabiliza...
