The oil was dominated by oxygenated monoterpenes (83.3%), with 1,8-cineole (58.5%) and α-terpineol (19.4%) as the major compounds. Monoterpene hydrocarbons gave a minor contribution (14.9%), with β-pinene (7.1%) and α-pinene (2.0%) as the most representative compounds. Interestingly,​ sesquiterpenoids,​ which are reported as volatile marker compounds of alligator pepper, were detected in only low levels here (0.6%). The chemical composition of the A. melegueta seed essential oil showed a significant variability depending on the geographic origin and genetic characteristics of the samples. For example, samples from Nigeria exhibited humulene (26.23%), (E)-ocimene (23.22%), (E)-caryophyllene (19.17%), and (S)-2-heptyl acetate (16.22%) as the major volatile constituents [24]. On the other hand, the seeds from the Central African Republic contained high levels of β-pinene (>30%) and about 50% sesquiterpene hydrocarbons [48], and an oil sample from Cameroon was made up of β-caryophyllene (8.5%), α-humulene (31.3%), and their epoxides (17.9% and 27.7%, respectively) [49]." \\
