| Abstract: | Alkaloid extracts of Petteria ramentacea (leaves, fruits, stem) contained cytisine, N-methylcytisine, anagyrine as major alkaloids, and lupanine, 5,6-dehydrolupanine and rhombifoline as minor constituents. Aphids (Aphis cytisorum) feeding on this plant accumulated cytisine in a concentration of 21 mmol/kg fresh weight (0.4 %). |
