A SURVEY OF QUINOLIZIDINE ALKALOIDS AND PHENYLETHYLAMINE TYRAMINE IN CYTISUS-SCOPARIUS (LEGUMINOSAE) FROM DIFFERENT ORIGINS

Distribution and content of the quinolizidine alkaloids and phenylethy lamine tyramine in various organs of Cytisus scoparius taken from diff erent localities in Germany, Russia, Italy and France were analyzed by capillary GLC. Sparteine and sparteine-derivatives like 11,12-dehydro sparteine are predominant in shoots and flowers whereas lupanine-type alkaloids are mainly accumulated in seeds, pods and roots. During the year no changes within the alkaloid pattern of the young developing sh oots could be observed, but the total alkaloid amount increases remark ably at the end of the vegetation period. With respect to the date of harvest only a limited Variation of the alkaloid profile and content c ould be found in shoots, flowers and roots taken from different geogra phical origins. In comparison the alkaloid pattern of seeds and pods v aried considerably which seemed to be correlated with the different st ales of maturity and not with the geographical origin. Phenylethylamin e tyramine is accumulated in flowers, green pods and young developing shoots. In young developing shoots the tyramine content declined drast ically during the vegetation period.
