In this paper, the fast-detecting method about the absolute content of erucic acid in rapeseed cake is studied, and by choosing a fixing liquid(ov-l) of low-partition ratio and weak polarity, a gas-chromatogra-phy analysis is made under high column temperature and higher gas-carrying flow rate and its quantitative calculation is determined by superposition method. And meantime the time is studied for steeping rapeseed cakes with the mixed solvent of benzene-petroleum ether (l:1v/v). Therefore, the method is easy and quick to operate and of high precision and its standard deviation is below 0.084%.

Nitrile acetyl derivatives of saccharides involving L-Arabinose D-Xylose D-Mannose D-Galactose and D-glucose were determined with gas chromatography under optimum conditions, the employment of a mixed column of fixed liquids composed by ov-210 and ECNSS-M, proved to have upgraded separation efficiency 3-6 fold. To attain faster and more accurate quantitative determinations, Xylitol was found to be a highly efficient internal standard, pretreatment of straw pulping waste liquor involeed the optimization of its hydrolysis, to yield nitrile acetyl derivatives of its saccharide contents. Experimental results indicated that carbohydrates were practically non-existent in the anaerobic treated waste liquor. It was noted that all carbohydrates existed as low molecular weight polysaccharose. Concentrations of monsaccharose before and after anaerobic treatment of the waste liquor were determined.
