杜鹃红山茶茶花的抗氧化能力研究

Study on Antioxidant Ability of Camellia azalea C.F.Wei Flower

本试验采用水提法、醇提法提取杜鹃红山茶茶花,检测提取液的抗氧化能力。同时探究料液比、提取时间、提取温度对提取液抗氧化能力的影响,以对DPPH自由基的清除能力为指标,确定提取杜鹃红山茶茶花的最佳工艺。结果表明,杜鹃红山茶茶花水提法的最佳工艺为料液比1∶300(g∶mL)、提取时间50 min、提取温度50℃;醇提法的最佳工艺为料液比1∶300(g∶mL)、提取时间30 min、提取温度60℃。

This experiment used water extraction and alcohol extraction methods to extract Camellia azalea C.F.Wei flowers.The antioxidant capacity of the extract was tested,and the effects of material liquid ratio,extraction time,and extraction temperature on the antioxidant capacity of the extract were explored.The optimal process for extracting Camellia azalea C.F.Wei flowers was determined based on the ability to eliminate DPPH free radicals.The result showed that the optimal process for water extraction of Camellia azalea C.F.Wei flowers is the ratio of material to liquid 1∶300(g∶mL),extraction time 50 min,and extraction temperature 50℃;the optimal process for alcohol extraction is a material liquid ratio of 1∶100(g∶mL),an extraction time of 30 min,and an extraction temperature of 60℃.
