Natural products represent an outstanding source of compounds able to play an important role in the treatment of several human diseases. For example, plants are an incredible source of bioactive compounds isolated from different species with an impressive structural diversity, representing a field of inspiration for the development of new drugs. The importance of natural products in drug discovery can be noted in the large number of drugs derived from plants available against different classes of disease. Due to the importance of the plants in drug discovery, several compounds have been isolated and evaluated from different species against Mycobacterium tuberculosis, which some of the most promising it will be described in this chapter.
