摘要

本研究用山楂水醇粗提物对山楂果实进行了筛选试验，提取的黄酮类化合物的体外抗菌活性高于粗提物，最低抑菌浓度（MIC）为5%~2.5%采用2，2-二苯基-1-苦基肼（DPPH）清除自由基的方法，测定了不同浓度提取物中山楂（Crataegus spp）和不同浓度提取物的抗氧化活性。结果表明，黄酮类化合物的含量为0.386mg槲皮素当量（QUE/g）。根据（DPPH）测定，干提取物显示出显著的抗氧化活性。

THE EFFECT OF FLAVONOIDS EXTRACTS FROM HAWTHORN (CRATAGUS OXYACANTHUS) AGAINST SOME GRAM-POSITIVE AND GRAM-NEGATIVE BACTERIA SPECIES

The present study has shown the screening test of Hawthorn fruits (Crataegus spp.) using crude hydroalcoholic extract and in vitro antimicrobial activity of extracted flavonoid which has shown more antibacterial activity than crude extract with minimal inhibitory concentration (MIC) values ranged from 5% to 2.5%. The amount of total flavonoid and antioxidant activity of Hawthorn fruits (Crataegus spp) in various concentration extracts and antioxidant activities of different concentration extracts were determined by radical scavenging by 2, 2-diphenyl-1-picrylhydrazyl (DPPH). The output showed that the contents of flavonoid were found to be 0.386 mg quercet in equivalents (QUE/g). Dried extract displayed remarkable antioxidant activity according to (DPPH) assays.
