摘要: 为了研究仙鹤草的收敛止血功效和抑菌作用,本实验通过构建大鼠皮肤损伤模型、烫伤模型,在探讨添加溶菌酶对仙鹤草新鲜和冻干粉末对两种大鼠模型的收敛止血功效和保存时间影响基础上,进一步考察仙鹤草对表皮葡萄球菌、大肠杆菌和铜绿假单胞杆菌的抑菌效果。实验发现:新鲜仙鹤草粉末对大鼠伤口愈合效果明显强于冻干粉末,略逊于云南白药;粉末中添加溶菌酶对大鼠伤口愈合效果没有明显影响,但可显著延长鲜草存放时间;表皮葡萄球菌、大肠杆菌和铜绿假单胞杆菌对仙鹤草提取物敏感程度依次降低。结果表明:仙鹤草收敛止血的有效活性主要存在于鲜叶中;其提取物可以抑制常见致病菌的生长;溶菌酶可延长仙鹤草的储存时间。

Abstract: In this study,the hemostasis convergence effect of Agrimonia pilosa Ledeb(including:fresh leaves and dried leaves powder containing lysozyme)on the healing of damage model and burn model rat was studied.The function of sterilization of A.pilosa extract on 3 common pathogenic bacteria including Staphylococcus epidermidis, Escherichia coli and Pseudomonas aeruginosa was investigated.The results showed that the wound healing effect of the fresh A.pilosa was higher than that of dried powder,but slightly lower than that of Yunnan Baiyao powder.The addition of lysozyme did not affect the healing ability of dried powder to rat wound but significantly prolonged its storage time.From these results,it was concluded that both fresh and dried powder can improve hemostasis convergence,while the fresh powder was better than the dried one.Antibacterial experiment showed that the crude extract of A.pilosa can strongly inhibit the growth of S.epidermidis and E.coli, but not for P.aeruginosa. These results demonstrated that active gradient,which existed in the fresh leaves of A.pilosa, showed the anti-bacterial ability.The addition of lysozyme can prolong the storage time of A.pilosa powder.
