Floral VOCs

Brugmansia/Datura. Floral VOCs of two Brugmansia spp. [B. arborea (L.) Lagerh. sub nom. D. arborea (L.), B. Candida Pers. sub nom. D. Candida (Pers.) Safe.] and three Datura spp. [D. inoxia Mmc., D. metel L., D. stramonium L.] were analyzed by Kawashima (1996). The results showed rich blends of monoterpenes (e.g., ocimene, pinenes, Umonene, sabinene) and oxidized congeners including esters (e.g., linalool, linalyl acetate, citroneUol, nerol, neryl acetate, neral, geraniol, geranyl formate, camphor, carvone, 1,8-cineol, fenchol) (Fig. 7.2) beside members of different classes of metabolites (e.g., phenylpropanoids, fatty acid esters), but almost no sesquiterpenes.
