Levels of Tannins and Flavonoids in Medicinal Plants: Evaluating Bioprospecting Strategies

Evidence-Based Complementary and Alternative Medicine, Volume 2012, Issue 1, 2012., 2012
There are several species of plants used by traditional communities in the Brazilian semiarid. An approach used in the search for natural substances that possess therapeutic value is ethnobotany or ethnopharmacology. Active substances that have phenolic groups in their structure have great pharmacological potential.
