[求助] How to analyse the non-reducing products after acid hydrolysis of corn stover? 已有1人参与

After using acid to hydrolysis the corn stover, I have got a variety of carbohydrates, including a lot of polysaccharide which can not be analyse by DNS method, which process should I use to make these non-reducing products measurable by DNS? would Adding 4% H2SO4 and heated in 121℃ for 1 hour do the trick? or is there a better plan?

thanks for reading this

why do not you use the HPLC method with those sugars likely present as standards? and you can chose the eluent according to those references. i strongly recommend you the NH2 or sugar column.
