依蘭依蘭/玫瑰/香芹子/茉莉等13種揮發性精油抗氧化力 - 精油

我只能說~愛美的香茗們..科學數據幫忙了驗證精油抗氧化力~

真是太棒啦~~~~~~~~~~v(￣︶￣)y


我把之前看過的一篇文獻 野人獻曝式的跟大家分享~

希望大家不吝指導 讓我這個新手更有豐富的視野~


文章名稱:Antioxidant Activities and Volatile Constituents of Various
Essential Oils
發表日期:J. Agric. Food Chem. 2007, 55, 1737-1742
作 者:ALFREDA WEI AND TAKAYUKI SHIBAMOTO

大 綱: Thirteen essential oils were examined for their antioxidant
activity using three different assay systems. Jasmine,
parsley seed, rose, and ylang-ylang oils inhibited hexanal
oxidation by over 95% after 40 days at a level of 500 microg/mL
in the aldehyde/carboxylic acid assay.
Scavenging abilities of the oils for the 1,1-diphenyl-2-
picrylhydrazyl (DPPH) radical ranged from 39% for angelica
seed oil to 90% for jasmine oil at a level of 200 microg/mL. The
greatest inhibitory activity toward malonaldehyde (MA) formation
from squalene upon UV-irradiation was obtained from parsley seed
oil (inhibitory effect, 67%), followed by rose oil (46%), and
celery seed oil (23%) at the level of 500 microg/mL.
The main compounds of oils showing high antioxidant activity
were limonene (composition, 74.6%) in celery seed, benzyl acetate
(22.9%) in jasmine, alpha-pinene (33.7%) in juniper berry,
myristicin (44%) in parsley seed, patchouli alcohol (28.8%)
in patchouli, citronellol (34.2%) in rose, and germacrene (19.1%)
in ylang-ylang.


我大略看過這篇文章~
作者把a-tocopherol 跟其他十三種精油作抗氧化力的比較~
(ps:a-tocopherol的"a" BBS打不出來 特用a表示~
而a-tocopherol生育醇是所有生育醇為最強抗氧化能力)

雖然十三種精油的抗氧化力都輸給a-tocopherol..
其中a-tocopherol對油脂類抗氧化力極佳..
但是綜合多次不同實驗條件..
作者提到香芹子與玫瑰精油的抗氧化能力其實不輸給a-tocopherol.(正副偏差)
在醫學有利條件下可衍生"這兩項精油對於皮膚氧化與未來疾病的預防"~

個人看到皮膚氧化的預防 眼睛就會亮起來!!!

另外其他精油分別為依蘭依蘭 茉莉 芹菜子 杜松子 廣霍香 歐白芷子
薰衣草 薑 檀香 洋甘菊 胡椒薄荷 都有抗氧化能力~

而全部的精油抗氧化能力都建立在清除自由基功能與抑制油脂氧化能力的條件下做~


以上..
有興趣的版友可以看這篇文章~
或許可以教教更多我沒看到的地方~
先說聲謝謝囉~~
