摘要
目的研究不同干燥温度(40、50、60、70、80℃)对NaHSO_(3)处理后干燥9 h后,延胡索贮藏前最适宜的干燥条件。方法利用高效液相色谱仪(High Performance Liquid Chromatography,HPLC)、电子眼等方法测定延胡索成分品质变化。结果在干燥时间为9 h条件下,干燥温度为80℃时,总灰分含量显著增加至3.47%,盐酸黄连碱、盐酸小檗碱含量分别达到0.04%、0.03%;延胡索甲素、延胡索乙素含量在70℃时最高,分别为0.13%、0.35%;脱氢紫堇碱在60℃时含量最高,为0.42%;干燥温度为50℃时,醇溶出物含量最高,为21.84%;随着干燥温度的升高,原阿片碱、盐酸巴马汀受温度影响均不显著,而延胡索样品褐变越严重。结论延胡索贮藏前最适宜干燥温度为40~60℃,水分含量低于6%。适宜的干燥温度,能最大限度地保障延胡索后期保鲜贮藏期间的品质,延长延胡索货架期,进而为延胡索保持较好的品质提供理论支撑。
The work aims to study the effects of different drying temperature(40,50,60,70,80℃)on NaHSO_(3)treatment and drying for 9 h,and determine the most suitable drying conditions for Corydalis yanhusuo before storage.High performance liquid chromatography(HPLC),electronic eye,and other methods were used to determine the quality changes of components in Corydalis yanhusuo.The results showed that under the condition of a drying time of 9 h at 80℃,the total ash content significantly increased to 3.47%,and the contents of berberine hydrochloride and berberine hydrochloride reached 0.04%and 0.03%respectively.The highest content of tetrahydropalmatine A and tetrahydropalmatine B was 0.13%and 0.35%at 70℃,respectively.The highest content of dehydrocolline was 0.42%at 60℃.When the drying temperature was 50℃,the highest content of alcohol soluble substance was 21.84%.As the drying temperature increased,the effects of temperature on protoopioid alkaloids and palmatine hydrochloride were not significant.However,the browning of Corydalis yanhusuo became more severe.The optimum drying temperature of Corydalis yanhusuo before storage is 40~60℃,at which the moisture content of Corydalis yanhusuo was less than 6%.Therefore,an appropriate drying temperature can maximize the quality of Corydalis yanhusuo during its later preservation and storage period,thereby extending its shelf-life and providing theoretical support for maintaining good quality of Corydalis yanhusuo.
