Abstract The chemical composition of four commercially available Helichrysum oils obtained from, H. bracteiferum (DC.) Humbert, H. cordifolium DC. H. hypnoides (DC.) R. Vig et Humbert and H. rusillonii Hochr., respectively of Madagascar origin were analyzed by GC/MS. Helichrysum bracteiferum oil was found to be rich in β-pinene (10.3%), 1,8-cineole (24.8%) and α-humulene (10.1%), whereas H. cordifolium oil contained β-caryophyllene (46.4%) and α-humulene (10.9%), as major components. Helichrysum hypnoides oil contained 1,8-cineole (51.5%) and H. rusillonii oil was rich in 1,8-cineole (11.7%) and β-caryophyllene (29.5%).
