Cancer stands as second most common cause of disease-related deaths in humans. Resistance of cancer
to chemotherapy remains challenging to both scientists and physicians. Medicinal plants are known to contribute
significantly to a large population of Africa, which is to a very large extent linked to folkloric claims which is part
of their livelihood. In this review paper, the potential of naturally occurring anti-cancer agents from African flora has
been explored, with suggested modes of action, where such data is available. Literature search revealed plant-derived
compounds from African flora showing anti-cancer and/or cytotoxic activities, which have been tested in vitro and
in vivo. This corresponds to 400 compounds (from mildly active to very active) covering various compound
classes. However, in this part II, we only discussed the three major compound classes which are: flavonoids, alkaloids and terpenoids.
