ABSTRACT:The essential oils extracted from the stems and roots of Elionurus hensii from “Plateau des Cataractes” present markedly different chemical profiles forming distinct chemotypes. A new chemotype for stem oil was also recently found in the same study area. This study aims tocharacterize the new chemotype and to propose objective criteria to distinguish between the three chemotypes. The essential oils of Elionurus hensii from sites at Loufoulakari, Nkama, Mpého, Loukoko and Sésé studied previously contained predominantlyp-mentha-2, 8-dien-1-ol/p-mentha-1(7), 8-dien-2-ol (from stems), and aristolone and limonene (from roots). A third profile, with mentha-1, 3, 8-triene/p-mentha-1(7), 8-dien-2-ol/undecanone as major constituents, was recently found in stems from Kimbélé on “Plateau des Cataractes”. The essential oils of Elionurus hensii from “Plateau des Cataractes” present three chemotypes: two for stems and one for roots. The existence of these three chemotypes was confirmed by multivariate statistics (PCA, AHC) on all the data collected over ten years.
