摘要：以贵州马蓝叶为研究对象,探究阴干、晒干、真空干燥、50℃烘干、100℃烘干、冷冻干燥、热风枪吹干、微波干燥和微波烘干9种干燥方式对马蓝叶叶片性状、药效成分和β-葡萄糖苷酶活性的影响。结果表明:微波干燥和微波烘干方式处理的干叶仍保留绿色舒展状态,色泽均匀,外观品相较好;50℃烘干的马蓝干叶含有较高质量分数的靛蓝和靛玉红,分别为0.68%和0.051%,并且叶片中β-葡萄糖苷酶具有较高活性(12.23 U/mg);微波干燥的马蓝叶具有外观较好、吲哚苷成分较高(8.84%)的优点,但是叶片中的β-葡萄糖苷酶几乎完全失活。
Taking Guizhou Baphicacanthus cusia as the research object,the effects of 9 drying methods,including shade drying,sun drying,vacuum drying,50℃oven drying,100℃oven drying,freeze drying,hot air gun drying,microwave drying and microwave post drying,on leaf properties,effective components andβ-glucosidase activity were investigated.The results showed that the dry leaves treated by microwave drying still retained green stretch state,uniform color and better appearance.The mass fractions of indigo and indirubin in the leaves of Baphicacanthus cusia dried in the oven at 50℃were 0.68%and 0.051%,respectively,andβ-glucosidase had higher activity(12.23 U/mg).The microwave dried Baphicacanthus cusia leaves had the advantages of good appearance and high mass fraction of indicant(8.84%),whereβ-glucosidase was almost completely inactivated.Therefore,the microwave drying technology could be popularized and applied in the drying process in the production of Baphicacanthus cusia.
