火索麻叶提取物的抗氧化、抗菌和促愈作用探索

Antioxidant, Antimicrobial and Wound Healing Potential of Helicteres isora Linn. Leaf Extracts

  • 摘要:
    目的探索火索麻叶提取物的抗氧化、抗菌和促进伤口愈合作用。
    方法用石油醚、氯仿、丙酮、不同浓度乙醇对火索麻叶进行植物化学成分筛选。采用DPPH自由基检测、NO清除测试、还原力分析评估抗氧化作用;采用纸片扩散法评估抗氧化及抗菌作用;采用大鼠动物模型评估伤口愈合能力。
    结果火索麻叶提取物主要含甾醇类及黄酮类成分,其醇提物部分具有显著抗氧化和抗菌作用(P < 0.05)。
    结论火索麻叶水醇提物可能是其发挥抗氧化、抗菌剂伤口愈合作用的活性部位。

     

    Abstract:
    ObjectiveTo investigate the antioxidant, antimicrobial and wound healing potential of Helicteres isora Linn. leaf extracts.
    MethodsThe petroleum ether, chloroform, acetone, ethanol and hydroalcoholic extracts of leaves were screened for phytochemicals. The 1,1-diphenyl-2-picrylhydrazyl (DPPH), nitric oxide (NO) radical scavenging tests and reducing power assays were performed to measure antioxidant activity; disc diffusion methods were used to evaluate antimicrobial potential. Wound healing activity was evaluated by incision and excision wound rat models.
    ResultsThe extracts contained mainly sterols and flavonoids. The hydroalcoholic extract showed remarkable antioxidant and antimicrobial potential and significant (P < 0.05) wound healing activity.
    ConclusionsThe identified activities of the hydroalcoholic extract may be attributable to its constituent phytochemicals.
