摘　　要：啤酒花称为蛇麻花,是一种多年生草本蔓性植物,古人取为药材。用于啤酒酿造已有上千年的历史,赋予啤酒特有的香味、爽快的苦味并能增加啤酒的防腐能力和非生物稳定性。啤酒花浸膏是一种抗氧化成分十分丰富的天然原料,具有重要的开发价值。本文选用DPPH.清除能力来确定抗氧化效果,先进行抗氧化能力的测定。然后对微波提取法先进行单因素实验再通过正交试验,以抗氧化效果为指标,确定了啤酒花干花抗氧化成分提取的最佳工艺条件是乙醇浓度为45%,料液比为1∶20,微波火力为80%,提取时间30 s。啤酒花浸膏抗氧化成分的抗氧化效果为630.36。并与同样提取条件的啤酒花浸膏、桑葚干、山楂干、石榴皮干提取物的抗氧化效果进行比较,发现啤酒花浸膏的抗氧化效果最好。The hop plant（Humunus Lupulus L.）is called snake manual twist,a perennial herbaceous plants,the ancients tendril sex off for medicine.It had been used in the brewage in thousands years,gave characteristic flavor and frank bitter of bee and increased antiseptic capability and anti-biological stability of beer.As for α-acid and flavonoids index,this experiement studied the extraction hop concrete by microraythis.This paper studied that the microwave extraction of the orthogonal test to determine the antioxidant components of hops flower the optimum extract conditions was ethanol concentration 45%,liquid ratio 1 ∶20,microwave power 80%,microwave time 30s.The antioxidant effects of hop concrete was 630.36.The same level of hops extraction conditions phytochemistry,mulberry doing,hawthorn,dry,pomegranate husk dry extract antioxidative effect comparison,found hops condensate of antioxidant best effect.
