 [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] [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. The distribution of these compounds was similar to that extract of the pomade, obtained by traditional enfleurage of the flowers over 3 days. \\+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.

Main constituents of the volatile fraction were 2-phenylethanol, linalool, methyl benzoate, geraniol, α-terpineol, and benzyl cyanide, in decreasing concentrations. The distribution of these compounds was similar to that extract of the pomade, obtained by traditional enfleurage of the flowers over 3 days. \\
