Murraya exotica L. - syn.Murraya paniculata (L.) Jack; Chalcas paniculata L.; Chalcas exotica (L.) Millsp. - Rutaceae
orange jessamine, mock orange, chinese box, Orangenraute
Evergreen shrub or tree, native to Southeast Asia (Indonesia); leaves ovate to elliptic, margin entire; flowers small, white, scented. Often grown as an ornamental for its terminal clusters of fragrant flowers.
„Rout et al. investigated the volatiles of Orange Jessamine flowers by various methods and found that the headspace of the live flowers is dominated by linalool, indole, (E,E)-alpha-farnesene, (E)-caryophyllene, germacrene d and bicyclogermacrene, whereas the absolute (obtained by pentane extraction followed by methanol extraction) has manool as the major component together with phenethyl alcohol, indole, nerolidol, benzyl benzoate and phenethyl benzoate“ http://www.bojensen.net/EssentialOilsEng/EssentialOils22/EssentialOils22.htm
„The principal constituents of the leaf oil were β-cyclocitral (22.9%), methyl salicylate (22.4%), trans-nerolidol (11.7%), α-cubebene (7.9%), (−)-cubenol (6.8%), β-cubebene (5.8%) and isogermacrene (5.7%). The most abundant constituent of the fruit essential oil was β-caryophyllene (43.4%). Other major components were (−)-zingiberene (18.9%), germacrene D (8.3%), α-copaene (5.5%) and α-humulene (5.1%).“

„The major components in the [flower CO2] extract were phenyl ethyl alcohol (3.3%), indole (1.2%), E-nerolidol (7.6%), benzyl benzoate (7.0%), phenyl ethyl benzoate (9.2%), manool (29.4%), etc.“

HS-SPME analysis of floral volatiles emitted by living M.paniculata flowers showed germacrene-D (39.6%) as main constituent, accompanied by caryophyllene (7.4%), bicyclogermacrene (6.9%), E- and Z-β-farnesene (5.9%), (E,E)-α-farnesene (5.8%), β-elemene, δ-cadinene (2.1%) and linalool (2%). Indole (6.6%), (Z)-jasmone (0.3%) and methyl-, ethyl- and benzyl salicylate as well as ethyl-, benzyl- and phenethyl benzoat contribute to the odor of the flowers.
