摘　　要：研究不同光质滇龙胆药材干燥品质的影响,利用遮光、红色、黄色、蓝色、绿色、紫色6种不同光照条件,将晒干方式作为对照,重点考察干燥后滇龙胆内水分含量及龙胆苦苷含量,同时对另外2种滇龙胆内主要活性成分马钱苷酸、獐牙菜苦苷进行了测定.结果显示绿光能降低其水分含量,并显著提高滇龙胆内龙胆苦苷的含量、马钱苷酸、獐牙菜苦苷的含量,为后期优化滇龙胆干燥工艺,进一步研究龙胆苦苷、马钱苷酸、獐牙菜苦苷的转化途径提供理论依据.Research on the effects the quality of dehydrating Gentiana rigescens according to light quality.Used sun-dried,dried in shade,red light,yellow light,blue light,green light,purple light,in seven different light conditions,and used sun-dried as control.Focusing on moisture content and the content of Genitopicroside in G.rigescens after dehydrating,the contents of loganic acid and swertiamarin were determined,representing the main active material in G.rigescens.The results shown that green light significantly decreased moisture content and increased the content of Genitopicroside,loganic acid and Swertiamarin.This work provides a theoretical basis for optimizing the drying process of G.rigescens and suggests further work in the transformation pathway of genitopicroside,loganin acid and swertiamarin.
