Flavonoids and oligomeric procyanidins, rutin, catechols, pheno-carboxylic acids (especially chlorogenic acid), sterols, amines, coumadins, and purines. The leaves and flowers contain more vitexin rhamnoside than the berries, and the berries contain more hyperoside than the leaves and flowers. Leaves contain the highest concentrations of flavonoids if they are harvested just before the plant blooms. Plants that grow during drought and after late frosts contain the highest concentrations of antioxidants (protecting the plant just as they protect cellular structures in the human body).
PARTS USED: Leaves and flowers, fruits
