Till date, no study has ever looked into the effect of extraction method on the chemical constituents ofthe essential oil of Helichrysum petiolare. This study therefore evaluated the effect of hydrodistillationand solvent free microwave extraction (SFME) methods on the chemical constituents of H. petiolarederived essential oils. The SFME derived essential oil was deep yellow and of higher yield than thepale yellow essential oil obtained through the hydrodistillation. There were substantial amounts ofmonoterpenes, monoterpene alcohols, sesquiterpenes, and sesquiterpene alcohols in both essentialoils obtained. The SFME derived essential oil had 62 compounds as against the 52 derived throughhydrodistillation. The SFME derived essential oil can therefore be suggested to be of better qualitythan of the hydrodistillation method. The compounds obtained in the essential oils have highpharmaceutical and cosmetic values, and as observed in this study, their quantity is dependent onmethod of extraction.
