| Abstract: | A TLC-UV method for the determination of lignin in polysaccharides of cone of Pinus koraiensis was reported. Active lignin was obtained by acid hydrolysis,and developed on GF-254 TLC-Plate by mixed Solventof dich1oro methane-ethylether. UV absorbance of the eluate was determined at 23Onm. The concentration oflignin was linearly related to absorbance within the range of 2~70pg/ml. The recovery was 100. 2% ~ 101.4% and RSD was 6. 5 %. |
