+The essential oil of black Ashanti pepper from Cameroon contained mainly β-caryophyllene (57.5%), β-elemene (5.1%), bicyclogermacrene (5.0%) and α-humulene (4.8%). The oil of white Ashanti pepper from Cameroon containened mainly β-caryophyllene (51.7%), cis-β-ocimene (6.6%), limonene (5.8%), β-pinene (4.5%), linalool (3.9%) and α-humulene (3.2%). \\
+"The most intense odor impressions of the essential oils of the various dried pepper fruits were given by professional perfumers as follows: P.nigrum (black) - fine, pleasant black pepper note; P.guineense (black) - black pepper top-note; and P.guineense (white) - pleasant white pepper note... the main compounds such as β-caryophyllene, germacrene D, limonene, β-pinene, α-phellandrene and α-humulene, as well as minor constituents such as δ-carene, β-phellandrene, isoborneol, α-guaiene, sarisan, elemicin, calamenene, caryophyllene alcohol, isoelemicin, T-muurolol, cubenol and bulnesol, are of greatest importance for the characteristic pepper odor notes..." \\
