Dispersion of natural products and medicinal secondary metabolites among plant taxons

One of the beneficial usages of the plants is their therapeutic quality. However, although most drugs supply in the world are synthetic in nature, but great majority of them originate from natural plants, with some not yet synthesized. Therefore, the efforts for screening of the plants to find new or replace the existing drugs, have continued. An important and considerable point in the screening is recognition of the victim plants for exploiting the interested metabolite. The objective of this study is to survey which metabolite in which plant can be synthesized.The study started by searching in google scholar, pub med, science direct and literature review in related books and journals. The results dealt with the introduction of typical plant families, genera and species supplying natural products such as alkaloids, tannins, resins, gums and latex among plant taxons that are used in pharmaceutical industry. In addition, it investigated the relationship between these products and the plant taxons. In concluded that with some exceptions, product varieties are found only in special plants. For example, alkaloids can be found in apocynaceae, ranunculaceae, solanaceae and papaveraceae; whereas, tannins are found in aceraceae, anacardiaceae and actinidiaceae.
