摘要：

Techniques are described for sample preparation and analysis of total ethanol-soluble sugars of conifer tissue, using a stabilized, diluted anthrone reagent. This reagent gave similar values for the principla free sugars, in contrast to a greater divergence with other anthrone reagents and with the phenol-sulphuric method. Non-carbohydrate interfering substances caused serious overestimations of the sugar content of fully cleared samples by a reducing sugar method. Deproteinizing was not required for colorimetric methods but decolorizing with charcoal was essential, largely to remove interfering phenolic compounds. © 1970.
