Abstract

Abstract Due to adverse effects of free radicals on human skin and increasing consumer demand for natural ingredients, essential oils from basil, Ceylon cinnamon bark, clove, juniper, lavender, oregano, rosemary, tea tree, thyme, and ylang-ylang were assessed for their antiradical activity. The oils were evaluated in the concentration range of 5—0.1 mg·mL−1, in which the three reference synthetic antioxidants are most often added to mass-produced cosmetics. Among all examined samples, C. cinnamon oil at a concentration of 5 mg·mL−1 showed the strongest DPPH radical scavenging activity (0.41 mg·mL−1 IC50), followed by clove oil, BHA, α-tocopherol, and BHT (0.82, 0.84, 0.88 and 0.93 mg·mL−1 IC50), respectively. At the same concentration, the reduction power of C. cinnamon oil was higher (1.64 mg·mL−1 Trolox Eq.) than that of α-tocopherol and BHT (1.42 and 0.80 mmol·L−1 Trolox Eq., respectively) but lower than that of BHA (1.81 mmol·L–1 Trolox Eq.). Antiradical activity of the other eight essential oils was low or negligible. C. cinnamon oil and clove oil are promising antiradical agents for skin care but according to our GC-MS analysis, these oils contain 0.29 % of cinnamaldehyde, 0.03 % of linalool, 0.02 % of D-limonene, and 0.02 % of eugenol or 0.41 % of eugenol and 0.002 % of linalool, respectively, which are monitored contact allergens in cosmetics. Such a product is not be suitable for consumers allergic to these substances but for the vast majority of consumers it does not pose a risk in terms of allergic manifestations.

锡兰肉桂和丁香精油作为有前途的自由基清除皮肤护理产品
摘要由于自由基对人体皮肤的不良影响和消费者对天然成分需求的增加,对罗勒、锡兰肉桂皮、丁香、杜松子、薰衣草、牛至、迷迭香、茶树、百里香和依兰的精油进行了抗自由基活性评估。这些油的浓度范围为5-0.1 mg·mL−1,其中三种参考合成抗氧化剂最常添加到大量生产的化妆品中。在所有检测的样品中,浓度为5 mg·mL−1的肉桂油表现出最强的DPPH自由基清除活性(0.41 mg·mL–1 IC50),其次是丁香油、BHA、α-生育酚和BHT(分别为0.82、0.84、0.88和0.93 mg·mL-1 IC50)。在相同浓度下,肉桂油的还原力(1.64 mg·mL−1 Trolox Eq.)高于α-生育酚和BHT(分别为1.42和0.80 mmol·L−1 Trooxx Eq。C.肉桂油和丁香油是很有前途的皮肤护理抗自由基药物,但根据我们的GC-MS分析,这些油分别含有0.29%的肉桂醛、0.03%的芳樟醇、0.02%的D-柠檬烯和0.02%的丁香酚或0.41%的丁香醇和0.002%的芳香醇,它们是化妆品中接触性过敏原的监测对象。这种产品不适合对这些物质过敏的消费者,但对绝大多数消费者来说,它不会造成过敏表现的风险。
