Don't Forget Essential Oil as Antioxidant for Aromatherapy~^^~

The study about the possible singlet oxygen scavenging activity of rutaceae essential oils; eight E oils (Bergamot, Grapefruit, Lemon, Lime, Mandarin, Orange sweet, Orange bitter, Yuzu) and four SD oils (Lime, Neroli, Petitgrain, Yuzu); has shown that most of essential oils dose-dependently scavenged singlet oxygen, suggesting their possible antioxidant activities.
Therefor, aromatherapy for the relaxation and reduction of oxidative stress may good for the pathogenesis of various diseases such as light-induced skin disorders and inflammatory responses.
Moreover, there was a research about antioxidant activity of essential oils and absolutes of 19 Thai aromatic plants and spices from 12 family. As the result, holy basil oil(Ocimum Sanctum Linn.) exhibits the highest antioxidant activity with IC50 of 0.6294mg/mL followed by phlai oil(Zingiber cassumunar Roxb., IC50=1.0599mg/mL) and ginger oil(Z. officinale , IC50=4.385mg/mL). In the part of absolute, saraphi (Mammea Siamemsis Kosterm.) exhibits the highest antioxidant activity with IC50 of 0.3271 mg/mL followed by white champaka(Micheli alba, IC50=0.7155 mg/mL) and frangipani(Plumeria alba, IC50= 1.0766mg/mL).

The research compared the antioxidant activities of essential oils among 4 ocimum species, ocimum basilicum, O.Canum, O.gratissimum and O.sanctum, found that O.gratissimum has the highest antioxidant avtivity.
