| Abstract: | The Effective composition of defatted silybum marianum seeds was extracted with different solvent by organic solvent-internal reflux method. The results showed that the silymarin yield with ethanol for 180 min was the highest (14.2 mg/g defatted seed) and the silybin yield with methanol for 240 min was the highest (6.6 mg/g defatted seed). The experiment showed that fat removal can increase yields of silymarin and silybin. |
