Qualitative Analysis Of Two Medicinal Native Plants Of Madagascar: Smilax Anceps, Dianella Ensifolia

Abstract

Traditional medicine is widely used in several countries. Madagascar has a great advantage due to its rich biodiversity characterized by several native and endemic species. The local population essentially uses plants to treat many diseases, as infusion or cataplasm from the seeds and the leaves. This study concerns the qualitative analysis of two native plants known by their analgesic property. We chose to study two plants widely used by local population: Dianella ensifolia and Smilax anceps. Dianella ensifolia is used for its property against jaundice and for its property to cure sexual imponent. Smilax anceps is used for its analgesic property. These two plants were collected in the eastern forest of the Island so that we have a representative quality of the local vegetation. The plants were submitted to various physico-chemical processes in order to obtain different extracts by increasing polarity of solvents. Phytochemical analysis done to these plants confirm the presence of some phytochemicals like polyphenols. These results could justify vernacular uses of plants and would be the beginning of further research for the identification of new molecules with healing properties.
