摘　　要：比较了高低海拔的山茶花活性成分及护肤功效的差异。以高、低海拔的红色山茶干花为材料,用φ(C2H5OH)=70%超声提取浓缩定容。通过对其总黄酮、总多酚和总蛋白含量进行测试分析,同时用DPPH自由基清除法、晚期糖基化终产物抑制率法和弹性蛋白酶抑制能力法比较高低海拔的山茶花抗氧化、抗糖化及抗皱紧致的护肤功效。结果显示,以干重计算,高海拔的山茶花提取液的总黄酮和总蛋白含量大约是低海拔的1.5倍,总多酚含量大约是低海拔的2.4倍,且高海拔的山茶花护肤功效显著优于低海拔的山茶花,为山茶花在化妆品领域的选择和应用提供了理论依据。The active ingredients in camellia japonica flowers at high and low altitudes,as well as their skin care effects,were compared.The dried red camellia japonica flowers at high altitude and low altitude were ultrasonically extracted with 70%ethanol,and these extracts were concentrated and then diluted to a constant volume.The content of total flavonoids,total polyphenols and total proteins was tested and analyzed.In addition,DPPH free radical scavenging,inhibition of the formation of advanced glycation end products,and elastase inhibitory capacity were measured to compare their skin care efficacies in antioxidation,anti-glycation,antiwrinkling and firming.The results showed that,based on the dry weight of camellia japonica flowers,the content of total flavonoids and total proteins of the flower at high altitude was approximately 1.5 times that of the flower at low altitude,while the content of total polyphenols was approximately 2.4 times that of the flower at low altitude.The skin care efficacy of camellia japonica flower at high altitude was significantly better than that of the flower at low altitude.This work could provide theoretical basis for the selection and application of camellia japonica flowers in the field of cosmetics.
