<正>以淡竹叶为原料，采用乙醇作为提取溶剂，研究了在微波辐射下提取茶多酚的工艺条件。探讨了茶多酚的提取方法及相应的提取条件；对微波功率、溶剂浓度、料液比、提取时间和提取级数等影响因素进行了研究，按照GB/T8313-2002标准，用UV-9200型分光光度计对茶多酚的吸光度进行了测定，同时对提取得到的茶多酚收率进行了分析。结果表明，微波辅助法从淡竹叶中提取茶多酚的适宜工艺条件为：淡竹叶在60%乙醇溶液中浓度为0.125g/mL，3级提取，提取功率320W，提取时间4min。此条件下茶多酚收率为1.43%。

This paper synthesizes the Cu2+schiff base complex of disproportionated rosin amine, and catalyzes urushiol oxypolymerization to polymer. The rosin amine reacts with the salicylaldehyde to product the schiff alkali, then the schiff alkali reacts with cupric acetate to synthesize the schiff alkali-copper complex. The result shows that catalyst concentration, reaction time, urushiol concentration and temperatures affect the polymer yield in oxypolymerization of urushiol system. Rational reaction condition is that ratio of the Cu2+schiff base complex of disproportionated rosin amine is 3%, urushiol concentration is 68.8 g/L, the system of reaction reacts 36 h at 30～C in alcohol dissolvent. The yield of deposition of polymer is 51.3%in rational reaction condition.
