Phytochemistry, bioactivities and induction of callogenesis of Tetracera

According to the World Health Organization (WHO), nearly 80% of African populations rely on traditional medicine for primary health care (WHO, 2002). Considerable economic benefits in the development of this medicine and in the use of medicinal plants for the treatment of various diseases have been reported in the literature (Muthu et al., 2006). Therefore, the search for active ingredients from plants is more relevant than ever. The use of plants as remedies goes back to the first man. Certainly the great ancient civilizations such as the Chinese, Indians, and North Africans provided the written evidence of man's ingenuity in using plants for the treatment of a wide variety of diseases (Gurni ,1981; Cinthia , 2014). The family Dilleniaceae consists of 18 genera and about 535 species distributed in four subfamilies.
