摘要
目的:针对滁菊长期堆置而造成腐烂的问题,探索有效的解决方法。方法:分别采用10℃贮藏、0℃冷藏、-10℃、-30℃冷冻的方法对滁菊进行保存,后烘干打粉,用醇提法提取总黄酮,硝酸铝-氢氧化钠法测定;用超声法提取有机酸类,紫外-分光光度法测量有机酸类提取率,比较不同的贮藏条件对滁菊总黄酮以及有机酸类含量的影响。结果:滁菊储藏的温度在0℃时,总黄酮含量维持稳定的时间最长,且总有机酸含量下降的最缓慢,外观影响小。结论:0℃为新鲜滁菊的最佳贮藏温度。
Objective:in view of Chuzhou chrysanthemum piled up for a long time and the rotten problem,it is aimmed to explore the effective solution. Methods:0 ℃,10℃ storage and cold storage of 30℃ ,10℃,frozen -method to save Chuzhou chrysanthemum for a few days,after baking powder and alcohol formulation wer used to extract flavonoids,aluminum nitrate,sodium hydroxide;Organic acids were extracted with ultrasonic method, UV - spectrophotometry to measure the extraction yield of organic acids,compare different storage conditions on the chuzhou chrysanthemum flavonoids and the influence of the content of organic acids. Results:in chuzhou chrysanthemum storage temperature is at 0℃ ,keeps the stability of the flavonoids content of the longest time, and cut down the content of total organic acids of the slow,and appearance also basically remain unchanged. Conclusion:0℃ for fresh chuzhou chrysanthemum is one of the best storage temperature.
