Mining chemodiversity from biodiversity: pharmacophylogeny of medicinal plants of Ranunculaceae / 中国天然药物

This paper reports a pharmacophylogenetic study of a medicinal plant family, Ranunculaceae, investigating the correlations between their phylogeny, chemical constituents, and pharmaceutical properties. Phytochemical, ethnopharmacological, and pharmacological data were integrated in the context of the systematics and molecular phylogeny of the Ranunculaceae. The chemical components of this family included several representative metabolic groups: benzylisoquinoline alkaloids, ranunculin, triterpenoid saponin, and diterpene alkaloids, among others. Ranunculin and magnoflorine were found to coexist in some genera. The pharmacophylogenetic analysis, integrated with therapeutic information, agreed with the taxonomy proposed previously, in which the family Ranunculaceae was divided into five sub-families: Ranunculoideae, Thalictroideae, Coptidoideae, Hydrastidoideae, and Glaucidioideae. It was plausible to organize the sub-family Ranunculoideae into ten tribes. The chemical constituents and therapeutic efficacy of each taxonomic group were reviewed, revealing the underlying connections between phylogeny, chemical diversity, and clinical use, which should facilitate the conservation and sustainable utilization of the pharmaceutical resources derived from the Ranunculaceae.

Preliminary pharmaphylogenetic study on Ranunculaceae / 中国中药杂志

<p><b>OBJECTIVE</b>To deal with the correlation between phylogeny, chemical constituents and pharmaceutical aspects of Ranunculaceae, namely a pharmaphylogenic study of this taxon.</p><p><b>METHOD</b>Based on chemical, pharmaceutical (both ethnopharmacologic and pharmacological) information, linking with different plant systems of Ranunculaceae.</p><p><b>RESULT</b>Chemical constituents of this taxon included several natural groups: benzylisoquinoline alkaloid, ranunculin, triterpenoid glycoside and diterpene alkaloid etc. Ranunculin and magoflorine were found to present simultaneously in some plants of this taxon.</p><p><b>CONCLUSION</b>Combining with therapeutic information, pharmaphylogenic research were in accordance with the phylogenetic system presented by Tamura that Ranunculaceae was proposed to be divided into six sub-families: Helleboroideae, Ranunculoideae, Cimicfugoideae, Isopyroideae, Thalictroideae and Coptidoideae. Results also supported the establishment of Cimicifugoideae.</p>
