PP纤维固载材料的制备及其对多酚的吸附研究

利用自制的光活性叠氮氯醋树脂,经UV光固定技术将明胶分子固定于高分子基材PP纤维表面,并将所合成的PP纤维固载材料用于水溶液中单宁多酚的吸附脱出。分别使用FTIR红外光谱法、电镜分析法对叠氮氯醋树脂、PP纤维固载材料及吸附后样品进行表征。结果表明,单宁多酚的吸附脱出效果显著。

Study on the Effective Components in Pomegranate Leaf and Extraction Method

Experimental results show that, all the sample of seasonal-temperature combinations, the effective component content is highest in November to collect leaves in the 25%; drying, and the strongest antioxidant activity. The results of this study will provide theoretical basis for the preparation process of pomegranate leaf tea. Results of the correlation between antioxidant activity and the effective components show that the antioxidant activity of pomegranate leaves is closely related to polyphenol content, in particular had significant correlation with the content of tannin polyphenols, flavonoids, and ellagic acid content had no significant correlation.
