An automated procedure for the estimation of total soluble carbohydrate in water extracts of herbage is described. Addition of different sugars to grass extracts showed good recoveries (96.5–104.5%) for glucose, fructose, sucrose and fructosan. Analysis of sugar mixtures similar in composition to grass extracts also gave good recoveries (98.7–100%). The automated technique enabled 20 samples per hour to be analysed with a lower coefficient of variation (1.96%) than for a manual anthrone method (3.85%).
