+Fractionated distillation of bay oil lead to the isolation of a compound that polymerised quickly, which was called myrcene (from Myrcia acris = Pimenta acris = Pimenta racemosa). As constituents of bay oil were recognized eugenol, myrcene, chavicol, methyl eugenol, methyl chavicol, phellandrene, and citral.\\

 "The foliar essential oils of Pimenta racemosa (Miller) J. Moore var. grisea (Kiaerskov) Fosb. are dominated by geraniol (0-85.52%), methyl eugenol (0.30-92.60%), and/or trans-methyl isoeugenol (0-86.32%). The foliar essential oils of Pimenta racemosa var. hispaniolensis (Urban) Landrum are dominated by 1,8-cineole (0.05-37.96%), methyl chavicol (0-22.61%), methyl eugenol (0-63.88%), γ-terpinene (0-16.67%), terpinen-4-ol (0.08-28.98%), and/or thymol (0-44.02%). The foliar essential oils of Pimenta racemosa var. ozua (Urban & E. Ekman) Landrum are dominated by 1,8-cineole (47.24-55.93%), limonene (3.62-30.07%), and/or α-terpineol (6.68-15.12%). The commercial bay oil (P. racemosa var. racemosa) is dominated by chavicol (<0.01-15.51%), eugenol (44.41-68.93%), methyl eugenol (0-11.88%), and/or myrcene (0.10-16.17%)." \\
