The production of polyphenols by two-year-old callus cultures from floral buds of Crataegus monogyna has been studied in relation to growth variation within a subculture period. Calli produce mainly proanthocyanidins (1074–2959 mg 100 g−1dry wt), B2 dimer (86–321 mg 100 g-−1dry wt), (−)-epicatechin 468–807 mg 100 g−1 dry wt), chlorogenic acid (213–769 mg 100 g−1 dry wt), and a major flavonoid hyperoside (61–143 mg 100 g−1 dry wt). Optimum production of polyphenols seems to be generally attained when maximal growth is reached.
