Chinese materia medica resource (CMM resource) is the foundation of the development of traditional Chinese medicine. In the study of sustainable utilization of CMM resource, adopting innovative theory and method to find new CMM resource is one of hotspots and always highlighted. Pharmacophylogeny interrogates the phylogenetic relationship of medicinal organisms (especially medicinal plants), as well as the intrinsic correlation of morphological taxonomy, molecular phylogeny, chemical constituents, and therapeutic efficacy (ethnopharmacology and pharmacological activity). This new discipline may have the power to change the way we utilize medicinal plant resources and develop plant-based drugs. Phylogenomics is the crossing of evolutionary biology and genomics, in which genome data are utilized for evolutionary reconstructions. Phylogenomics can be integrated into the flow chart of drug discovery and development, and extends the field of pharmacophylogeny at the omic level, thus the concept of pharmacophylogenomics could be redefined in the context of plant pharmaceutical resources. This contribution gives a brief discourse of knowledge pedigree of pharmacophylogeny, epistemology and paradigm shift, highlighting the theoretical and practical values of pharmacophylogenomics. Many medicinally important tribes and genera, such as Clematis, Pulsatilla, Anemone, Cimicifugeae, Nigella, Delphinieae, Adonideae, Aquilegia, Thalictrum, and Coptis, belong to Ranunculaceae family. Compared to other plant families, Ranunculaceae has the most species that are recorded in China Pharmacopoeia (CP) 2010. However, many Ranunculaceae species, e. g., those that are closely related to CP species, as well as those endemic to China, have not been investigated in depth, and their phylogenetic relationship and potential in medicinal use remain elusive. As such, it is proposed to select Ranunculaceae to exemplify the utility of pharmacophylogenomics and to elaborate the new concept empirically. It is argued that phylogenetic and evolutionary relationship of medicinally important tribes and genera within Ranunculaceae could be elucidated at the genomic, transcriptomic, and metabolomic levels, from which the intrinsic correlation between medicinal plant genotype and metabolic phenotype, and between genetic diversity and chemodivesity of closely related taxa, could be revealed. This proof-of-concept study regards pharmacophylogenomics as the updated version of pharmacophylogeny and would enrich the intension and spread the extension of pharmacophylogeny. The interdisciplinary knowledge and techniques will be integrated in the proposed study to promote development of CMM resource discipline and to boost sustainable development of Chinese medicinal plant resources.
