Feeding experiments with 13C- and fluorine-labelled precursors revealed that the biosynthesis of 2-aminobenzaldehyde in flowers of Robinia pseudoacacia and Philadelphus coronarius is realized by transformation of anthranilic acid to indole followed by oxidative ring opening and hydrolysis of the resulting N-formyl-2-aminobenzaldehyde. \\ | Feeding experiments with 13C- and fluorine-labelled precursors revealed that the biosynthesis of 2-aminobenzaldehyde in flowers of Robinia pseudoacacia and Philadelphus coronarius is realized by transformation of anthranilic acid to indole followed by oxidative ring opening and hydrolysis of the resulting N-formyl-2-aminobenzaldehyde. \\ | ||

- | {{: | + | "The volatile constituents of both dried and fresh leaves, twigs and flowers of Philadelphus coronarius L. (Hydrangeaceae) were isolated by hydrodistillation and analyzed by GC/FID and GC/MS. There were major differences between the various oils. For example, epi-13-manool (47.6 %) was the major component of the fresh flower oil, but was not detected in the dried fower oil, whereas isolongifolol (15.5%), 2-nonanol (11.1%) and 7-hydroxycoumarin (9.7%) were the principal components of the dried flower oil. In the oils of both the fresh and dried leaves the major constituent was (E, |
