【摘要】 研究了在不同的烘干温度(40、60、80、105℃)条件下,粗枝木麻黄(Casuarina glauca)和细枝木麻黄(C.cunning-hamiana)中可提取的总酚、可溶态缩合单宁、纤维素结合态缩合单宁、蛋白质结合态缩合单宁含量的变化.结果表明:粗枝木麻黄在60℃时可提取的总酚含量最多;细枝木麻黄在80℃可提取的总酚含量最多.粗枝木麻黄中的可溶态缩合单宁在80℃时有最大提取量;细枝木麻黄中的可溶态缩合单宁在60℃时有最大提取量.两种木麻黄的纤维素结合态缩合单宁和蛋白质结合态缩合单宁含量均随着温度的升高呈上升趋势.本实验为进一步探讨干样中单宁的最适提取条件奠定了基础.更多还原

【Abstract】 The effect of drying temperature(40℃,60℃,80℃,and 105℃) on extraction of total phenolics and condensed tannins of two Casuarina species(C.glauca,C.cunninghamiana) was studied.Contents of the total phenolics and condensed tannins changed with drying temperature.The drying temperature for the highest extraction of total phenolics was 60℃ for C.glauca and 80℃ for C.cunninghamiana.While the drying temperature for the highest extraction of extractable condensed tannins was 80℃ for C.glauca,and 60℃ for C.cunninghamiana.But the pattern of protein-and fiber-bound condensed tannins was the identical,namely increased with temperature.更多还原
