Taxonomy

To further my research I found the taxonomy of each plant in which my secondary metabolites are most abundant.  Information was taken from the Ethnobotanical Database of Bangladesh and Doctor Duke's Phytochemical and Ethnobotanical Databases. First I discovered the plant most abundant in the chemical on Dr. Dukes page, then I found the taxonomy on EthnobotanyBD.
