+大叶醉鱼草 da ye zui yu cao (chin.), butterfly bush, summer lilac, **Schmetterlingsflieder**, Sommerflieder
 Shrub, native to China, naturalized and cultivated elsewhere as ornamental; leaves narrowly elliptic or ovate, abaxially tomentose or pubescent with stellate hairs; flowers fragrant, violet to dark purple, sometimes white, with an orange-yellow throat. \\

+The flower scent collected using the dynamic headspace adsorption method and analysed by GC-MS showed 3-hydroxy-2-butanone (acetoin; 1.6%), hexanol (1.6%), 2-hydroxyheptan-3-one (2.5%), 3-hydroxyheptan-2-one (2.0%), benzaldehyde (4.9%), (E)-β-ocimene (2.1%), (E,E)-α-farnesene (20.0%), β-cyclocitral (2.0%), oxoisophorone oxide (10.1%), oxoisophorone (45.4%), and dihydrooxoisophorone (1.0%) as main components. Minor components were e.g. hexyl acetate (0.9%), cis 3-hexenyl acetate (0.3%), phenylacetaldehyde (0.7%), benzyl alcohol (0.5%), cinnamic aldehyde cis/trans (0.2/0.3%), 2-phenylethanol (0.5%), cinnamic alcohol (0.1%), (Z)-β-ocimene (0,2%), lavandulol (0.2%), verbenone (0.1%), geranylacetone (0.1%), (Z,E)-α-farnesene (0.6%), farnesol (0.1%), 6-methyl-5-hepten-2-one (0.6%). \\

 Benzaldehyde, 2-phenyl ethanol, and benzyl alcohol were among the dominating compounds in B. davidii flower scent. \\

+"Floral scents of B. davidii were collected using dynamic headspace adsorption and identified with coupled gas chromatography and mass spectrometry. In total, 33 compounds were identified from the inflorescences of B. davidii. The identified scents were divided into five chemical classes based on their biosynthetic origin: irregular terpenes, monoterpenoids, sesquiterpenoids, fatty acid derivatives, and benzenoids. The scent profiles in all populations were dominated by few components, such as: 4-oxoisophorone, (E,E)-α-farnesene, and 1-octen-3-ol." \\
