摘要: 为筛选防晒的天然原料,选择18种天然药食植物进行防晒能力分析,比较其抗氧化能力、吸收紫外光的能力和抑制酪氨酸酶的活性。结果表明,玫瑰花、丁香、苦丁茶和绿茶的乙醇提取液具有较强的清除自由基活性,IC50分别为35.00、65.00、60.00、42.00 μg/mL;在乙醇提取液浓度为0.2 mg/mL时,葛根、玫瑰花、黄连、苦丁茶、丁香在紫外中波区域有较大吸收值,吸收值依次减弱;黄连、苦丁茶、姜黄、玫瑰花、虎杖、槐米、丁香在紫外长波区域有较大吸收值,吸收依次减弱。桑白皮、虎杖、红景天、绿茶、花椒、葡萄子、玫瑰花、槐米、苦丁茶对酪氨酸酶活性的平均抑制率依次减弱。

关键词: 药食植物, 抗氧化能力, 紫外吸收, 酪氨酸酶活性

Abstract: In order to screen the natural raw materials of sunscreen, 18 natural medicine plants were selected for sun protection analysis. The antioxidant capacity, ultraviolet light absorption capacity and tyrosinase inhibition activities of the materials were compared. The results showed that Rosae rugosae flos, Eugenia caryophyllata Thunb., Ilex latifolia Thunb. and green tea had strong scavenging activity of free radical. The IC50 of their extracting solution were 35.00, 65.00, 60.00 and 42.00 μg/mL, respectively. When the concentration of ethanol extracting solution was 0.2 mg/mL, Pueraria lobatae radix., Rosae rugosae flos, Coptis chinensis Franch., Ilex latifolia Thunb. and Eugenia caryophyllata Thunb. had a larger absorption value in the ultraviolet medium wave region, and the absorption value decreased successively. The absorption value of Coptis chinensis Franch., Ilex latifolia Thunb., Curcuma Longa Rhizoma., Rosae rugosae flos, Reynoutria japonica Houtt., Sophora japonica L. and Eugenia caryophyllata Thunb in the ultraviolet long wave region were relatively large, and the absorption was decreased successively. The average inhibition rate of Polygoni cuspidati rhizoma, Reynoutria japonica Houtt., Rhodiolae crenulatae radix, green tea, Zanthoxyli pericarpimum, the seed of Vitis vinifera L., Rosae rugosae flos, Sophora japonica L. and Ilex latifolia Thunb. on tyrosinase activity decreased in turn.

Key words: edible and medicinal plants, antioxidant capacity, ultraviolet absorption, tyrosinase activity
