中文摘要: 为探讨蓝靛果果渣花色苷的最佳提取工艺，采用常温溶剂浸提、加热溶剂浸提、超声辅助提取、微波辅助提取4种提取技术提取蓝靛果果渣中花色苷，通过优化其提取时间，研究不同方法对果渣中花色苷得率及结构的影响。结果表明：4种方法的最佳提取时间分别为90、90、35、0.67 min。其中微波辅助提取法提取蓝靛果果渣花色苷的得率为233.4 mg/100 g，与超声辅助提取法相比花色苷得率提高75.0%，与加热溶剂浸提相比花色苷得率提高73.0%，与常温溶剂浸提相比花色苷得率提高78.1%。说明在微波辅助提取工艺的辅助下果渣中花色苷的提取效率得到了极大地提高。
Abstract:The different extraction technologies such as cold solvent extraction，heat solvent extraction，ultrasonic and microwave assistance extraction were used to extract the anthocyanins from Lonicera caerulea residue.The extraction yield and the structure of anthocyanins were studied through optimizing the extraction time of anthocyanins from Lonicera caerulea residue.The results indicated that the optimum conditions time of these four extracting technologies were 90，90，35，0.67 min，respectively.The yield of anthocyanins with microwave assistance extraction was 233.4 mg/100 g，which compared with cold solvent extraction increasing 78.1%，compared with ultrasonic assistance extraction increasing 75.0%，and compared with heat solvent extraction increasing 73.0%.This result showed that the microwave assistance extraction technology greatly improved the yield of anthocyanins from Lonicera caerulea residue.
