浙麦冬产地加工不同干燥方法研究

Studys on Different Drying Methods of Habitat Processing of Ophiopogon japonicus in Zhejiang

目的:科学研究浙麦冬产地适宜的加工和干燥方法。方法:通过不同温度直接烘干、类似传统的烘后回潮再烘的干燥方式、微波杀青、100℃高温杀青、去须根干燥以及传统的加工干燥等方式加工浙麦冬,并测定其总皂苷、总黄酮和总多糖等三类成分的含量。结果与结论:浙麦冬产地加工以60℃直接烘干,其总皂苷、总黄酮含量与传统加工方式相似,总多糖含量高于传统加工,可以代替传统的加工方式;100℃高温杀青、微波杀青或去须根等方式干燥,对总多糖含量影响较大。

Objective： To study a suitable processing method for Ophiopogon japonicas in producing area. Methods：The O. japonicas were dried at different temperature,dried similar to traditional processing,wrapped by microwave at 100 ℃,dried by removing fibrous root, and compared with the traditional process. And the total saponins, polysaccharide and flavonoids were determined. Results and Conclusion： The results show that contents of total saponins and total flavonoids in O. japonicas dried at 60 ℃ were similar to the traditional processing, the total polysaccharides was higher than traditional processing,and the method of dried at 60℃ can replace the traditional processing. The total polysaccharides was lower in O. japonicas wrapped by microwave,high temperatures（ 100 ℃）,or dried by removing fibrous root.
