Abstract:
... The chemical composition of a volatile concentrate of the flowers of Thevetia peruviana and Allamanda cathartica were analyzed by GC/MS. The main volatile components identified in the flowers of T. peruviana were palmitic acid (22.9%), (E)-beta-ionone (17.2%) and 1.8-cineole (10.6%). The major volatiles of the flowers of A. cathartica were linalool (39.3%), dendrolasin (20.2%) and beta-caryophylle ...

Abstract:
... P-lonone has been reported to induce the cytochrome P450 (P450) 2B1 in rats. In this study, the effects of p-ionone and an isomer, a-ionone, on liver P450 1A and 2B expression in Sprague Dawley rats were investigated. Subcutaneous administration of α- and β-ionone 72 and 48 hr prior to sacrificing the animals induced the liver microsomal P450 1A and 2B proteins. P450 2B1 induction was associated w ...

Abstract:
... Carotenoids are nutritionally important tetraterpenoid pigments that upon oxidative cleavage give rise to apocarotenoid (norisoprene) aroma volatiles. β-Carotene is the predominant pigment in orange-fleshed melon (Cucumis melo L.) varieties, reaching levels of up to 50 microgram/g FW. Pale green and white cultivars have much lower levels (0-10 microgram/g FW). In parallel, β-ionone, the 9,10 cleav ...

Abstract:
... Carotenoids are thought to be the precursors of terpenoid volatile compounds that contribute to flavor and aroma. One such volatile, beta-ionone, is important to fragrance in many flowers, including petunia (Petunia hybrida). However, little is known about the factors regulating its synthesis in vivo. The petunia genome contains a gene encoding a 9,10(9',10') carotenoid cleavage dioxygenase, PhCCD ...
