The Key point here:


Market adulteration supervision Part 1


Conba is responding actively to the trends of EGB product admission "threshold" improvement, and conducting market adulteration supervision work. It performs inspections to rutin, free quercetin, free kaempferol, free isorhamnetin and genistein to analyze and judge if there is any adulteration and water extraction, etc.


Combining HPLC chromatogram, we found:


1) water extraction: it is found that tutin content is low with only 1% content, while the contents of free quercetin, kaempferol and isorhamnetin are abnormally high, from which we can make a preliminary judgment that its extract has been partially hydrolyzed in preparation process, so it is suspected that water extraction or acid water extraction might be adopted in the preparation process, as shown in Figure 1;
