Antioxidant capacity and antityrosinase activity of different polanity extracts in lavender Leafs

目的研究薰衣草叶提取物不同极性部位的抗氧化及抑制酪氨酸酶活性。方法提取不同极性部位的浸膏分别进行抗氧化和抑制酪氨酸酶活性实验。结果总抗氧化能力(TAC)乙酸乙酯相>正丁醇相>二氯甲烷相>石油醚相;乙酸乙酯相、正丁醇相、二氯甲烷相、石油醚相对·OH的清除率分别为83.06%、51.27%、47.74%、43.28%;乙酸乙酯相、二氯甲烷相、正丁醇相、石油醚相对超氧阴离子自由基(O2)的清除率分别为80.26%、52.34%、45.26%、28.22%。;正丁醇相、乙酸乙酯相、二氯甲烷相、石油醚相对酪氨酸酶抑制率分别达73.52%、36.42%、28.55%、20.21%。结论本研究对下一步薰衣草资源的综合利用研究具有重要意义。

Objective To study the antioxiation antityrosinase activity of different polanity extracts in Lavender leaves.Methods-Petroleum ether（ PE）,methylene chloride（ MC）,ethyl acetate（ EA） and N- butanol（ NB） were respectively used to extract the leaves of Lavender.to determine the antioxidation,antityrosinase activity of the four fractions.Results The activity of TAC is EA NB MC PE; The ability of scavenging ·OH in four fractions were 83.06%（ EA）,51.27%（ NB）,47.74%（ MC）,43.28%（ PE）; The ability of scavenging Superoxide anion.were 80.26%（ EA）,52.34%（ MC）,45.26%（ NB）,28.22%（ PE）; The ability of inhibit tyrosinase were 73.52%（ NB）,36.42%（ EA）,28.55%（ MC）,20.21%（ PE）.Conclusion This study has significant fuction in comprehensive Utilization of Lavandula.
