Abstract:
The determ ination o f to ta l stero l content in p lant o il pitch w as studied by improved Lieberm an-Burchard co ler ime try. The sam ple so lution w ithout chrom ogenic agent w as used as the blank so lution, and the stero l content obeyed L ieberm an-Burchard law in the range o f 0. 034~ 0. 344 mg /mL w ith good linear ity. The to ta l content o f stero l in plant oil pitch w as abou t 12.1% and in the ex traction the content of stero l w as abou t 74.5%. The SD was 0.0603%; the sam ple recovery ra tew as betw een 94.8% and 98. 1%. Th ism ethod w as s imp le and the detec tion was co sts low. The color reaction was distinc t, and co lo r stab iliza tion tim e was 015 hour. Them ethod wou ld be suitable for corporations. laboratory, and offers it im po rtant re ference for the application o f high-va lue com ponents in the p itch.
