| Abstract:
The production and distribution of tropane alkaloids in organs of wild Atropa belladonna plants was studied by HPLC. Two different growth stages were examined in June and July and in addition berries and seeds in September 1991. A seasonal variation in total alkaloid content and alkaloid patterns of these plant parts was observed. Hyoscyamine was the main product throughout. A diurnal variation of tropane alkaloid content could be determined. Two peaks were significant: maximal alkaloid yields were detected at early night and at early morning. In maturing seeds, the alkaloid content was highest in the afternoon. | |
