Essential Oil from Artemisia sieversiana Willd. and Development of Related Oil-in-Water Emulsions

Resumo

Essential oil (EO) from Artemisia sieversiana Willd. growing in Buryatia was characterized by gas chromatography with mass-spectrometric detection (GC-MS). Chamazulene (36%), which possesses anti-inflammatory and antioxidant properties, was the main constituent. EO-based emulsions with rather narrow particle-size distributions and average sizes û nm were prepared by combining mechanical dispersion and high-pressure homogenization procedures.
