The effect of hydrophobic additive on the seed precipitation from sodium aluminate solution was studied by adding fatty acid and heneicosane at different proportions. The results show that when the mass fraction of fatty acid is in the range of 32%-49% and the additive concentration in sodium aluminate solution is 150×10-6 g/L, the rate of precipitation increases, but the particle size of Al3 and Al2O3 reduces.

The main compounds were 5-methyl-2(3H)-furanone, diethyl succinate, furfural, hexadecanoic acid, linolenic acid, 5-methylfurfural, oleic acid, linoleic acid, etc.

并利用气相色谱仪-质谱仪对罗望子萃取物的化学组成进行了分析鉴定，并用面积归一化法测定了各种成分的质量分数，共鉴定了48种成分，占总质量分数为98.35%，其中主要成分为：5-甲基-2(3H)-呋喃酮、丁二酸二乙酯、糠醛、十六酸、亚麻酸、5-甲基糠醛、油酸、亚油酸等。

Significantly genotypic differences and great variations were detected in grain β-amylase activity,β-glucan and protein fraction contents. The largest variation and highest average value of β-amylase activity were found in Hangzhou 2006-2007, while the trend of coefficient of variation was opposite to the mean content of β-glucan over different environments. Hordein content had the highest correlation coefficient with β-amylase activity among four protein fractions.
