Abstract
Pulse-feeding of appropriate amino acids to rapidly-growing callus of Ceanothus americanus led to accumulation of novel tetrapeptides that w ere precursors of the macrocyclic alkaloids characteristic of the fiel d-grown plant. Slow-growing pigmented callus lines maintained on a var iety of media exhibited no detectable alkaloid metabolism but accumula ted several flavonoids, some previously not reported in the plant.
