摘要
对毛竹叶、柄中多糖和类黄酮进行中试提取研究。分别添加不同的酶,探讨对其提取率和纯度的影响。并通过乙醇浓度梯度变化考察对毛竹叶、丙类黄酮提取率的影响。实验结果表明,添加一定量的纤维素酶,可以显著提高毛竹叶、柄活性多糖、类黄酮的中试提取率和纯度,提取毛竹叶、柄类黄酮的理想乙醇浓度应在30%～50%范围内。
In this study, pilot extraction polysaccharides and flavonoids from moso bamboo leaves and stemes were discussed. By adding different enzymes in pilot extraction processes, effects on the extraction ratio and purification were discussed, furthermore, optimal alcohol concentration of flavonoids extraction was studied by changing alcohol content. The results showed that＂ proper addition of cellulase can increase the extraction rates and purities of polysaccharides and flavonoids from moso bamboo leaves and stemes, remarkably, and the ideal alcohol concentration of flavonoids extraction is 30% -50%.
