摘　　要：研究超微粉碎和普通粉碎对山银花(灰毡毛忍冬L.macranthoides)微粒结构、有效成分含量、活性成分溶出率及其抗氧化能力的影响。结果显示,超微粉碎导致了山银花物料微粒结构的改变,即可使组织细胞壁及粗纤维结构破坏;同时提高了绿原酸、灰毡毛忍冬皂苷乙、川续断皂苷乙、木犀草苷、咖啡酸等活性成分的溶出量;超微粉中绿原酸的溶出度和溶出速率与细粉相比均具有较明显的提高;超微粉清除DPPH·的能力是细粉的1.36倍(浓度均为60mg/mL时)。超微粉碎技术改善了山银花的物理化学特性,破坏了其原有细胞壁及粗纤维的致密网状结构,提高了活性成分溶出量和抗氧化能力。In order to explore the comprehensive utilization value of L.macranthoides,investigated the particle structure,effective compositions contents,dissolution rate and antioxidant activity of L.macranthoides processed ultrafine and common grinding.It was found that the ultrastructure of L.macranthoides was changed by ultrafine grinding,and its cell wall and crude fiber structure were destroyed.The dissolution contents of chlorogenic acid,Macranthoidin B,Dipsacoside B, Luteolin 7-glucoside and caffeic acid were increased after ultrafine grinding.The dissolution rate of chlorogenic acid from ultra-fine griding powder was significantly higher than that of common griding power of L.macranthoides.Furthermore,scavenging ability of DPPH · were investigated.The DPPH ·scavenging ability of L.macranthoides power were increased to 1.36 times by ultrafine grinding.Ultrafine grinding improved the physicalchemical properties of L.macranthoides,destroyed its intact structure of tissues and cells at the original state,improved its antioxidant capacities,and had a certain potential in the application of food and medicine industries.
