忻州地区款冬花适宜采收期及初加工研究

Study on Suitable Harvest Time and Primary Processing of Tussilago farfara in Xinzhou Area

为确定山西省忻州地区款冬花适宜的采收期及加工方式,本文采取HPLC法测定了不同采收期有效成分款冬酮及花蕾产量。结果表明:秋季,随着时间的增加,款冬花产量呈现先增后减的趋势,11月10日达到最大,鲜花产量为375 kg·667 m^(-2)。款冬酮含量随着时间的增加而增加,11月20日达最大,为0.116%。结合产量和款冬酮含量综合考虑,忻州地区款冬花适宜采收期为11月10-20日;综合考虑加工时长、折干率和款冬酮含量,适宜加工方式为50℃烘干处理。

In order to determine the suitable harvest time and processing method of Tussilago farfara in Xinzhou area of Shanxi Province,HPLC was used to determine the effective components of Tussilago farfara in different harvest time and the yield of flower bud.The results showed that:in autumn,with the growth of time,the yield of Tussilago farfara increased first and then decreased,and reached the maximum on November 10,with the yield of 375 kg·667 m^(-2).The content of tusonone increased with the increase of time,and reached the maximum on November 20,which was 0.116%.Considering the yield and the content of Tussilago farfara,the suitable harvest time of Tussilago farfara in Xinzhou is November 10-20;considering the processing time,drying rate and the content of Tussilago farfara,the suitable processing method is drying at 50℃.
