-Major constituents of M.tenuifolia flower volatiles are the sesquiterpenes α-copaene (35%) and β-caryophyllene (26%). Monoterpenes like α-pinene (5%), β-pinene (2%), myrcene (7%), limonene (3%), 1,8-cineole (4%) are also present, but the scent impression is dominated by Δ-decalactone (0.4%). \\
+The typical coconut scent of M.tenuifolia flowers is produced primarly by δ-decalactone (29.5%), accompanied by γ-decalactone (1.0%), and a series of methyl ketones like 2-undecanone (2.9%), and 2-tridecanone (9.5%). \\

+The main compounds of M. tenuifolia flower headspace (HS-SPME-GC-MS; relative content) were the sesquiterpenoids β-caryophyllene (69.0%), α-copaene (10.2%), and caryophylladienol II (7.2%). The scent-impression dominating δ-decalactone is released by petals (3.6%) and columns (0.5%). \\
