 "The essential oil of Plumeria rubra forma acutifolia (Poir.) Woodson cv. ‘Common Yellow’ growing in Hawaii was extracted by simultaneous distillation and extraction (SDE). The essential oil was analysed with GC and GC-MS, and a total of 74 compounds were identified. Linalool, phenylacetaldehyde, trans,trans-farnesol, β-phenylethyl alcohol, geraniol, α-terpineol, neral and geranial were found to make a major contribution to the floral scent of this flower." \\

 "The essential oil of one of the cultivars of Plumeria rubra L. ‘Irma Bryan’ growing in Hawaii was extracted by simultaneous distillation and extraction (SDE). The essential oil was analysed with GC and GC-MS, and a total of 67 compounds were identified. β-Phenylethyl alcohol, phenylacetaldehyde and methyl cinnamate were found to make a major contribution to the floral spicy scent of this flower." \\

 [The Constituents of Volatile Oil from Plumeria rubra L. var. acutifolia Bailey., Huang, Mei-yan, et al., Journal of Anhui Traditional Chinese Medical College, 4 (2005), 18]
-Frangipani flowers give off their fragarance early in the morning and at dusk, which is reminescent of rose, citrus, and cinnamon, with jasmine, coconut and fruity undertones. Concrete and absolute from the flowers made with 1,1,1,2-tetrafluorethane and ethanol had similarly strong and characteristic odors, strikingly close to that of the living flower. Non-volatiles such as triterpenols (amyrin, amyrin acetate), hydrocarbons (nonacosene), plumericin and isoplumericin, α-tocopherol (0.4%), phenylethyl salicylate, and (E,E)-farnesol made up the greatest part of the absolute oil. Main constituents of the volatile fraction were 2-phenylethanol, linalool, methyl benzoate, geraniol, α-terpineol, and benzyl cyanide. Distribution of these compounds is similar to that extract of the pomade, obtained by traditional enfleurage of the flowers over 3 days. \\
