Identification and Assessment of Therapeutic Phytoconstituents of Catharanthus roseus through GC-MS Analysis

The leaves of Catharanthus roseus (L.) G. Don contain a large number of diverse secondary metabolites, making them comparably complex. The Catharanthus genus has received increased interest from scientists in recent years due to its extensive applications in several domains, including the pharmaceutical sector, where precise characterization of its characteristics is required. An effective inquiry technique is needed for chemo-profiling to identify the metabolites in plant samples. The main goal of this research is to provide supplementary data on the chemical composition of the leaves of twenty-five different accessions of C. roseus through the application of gas chromatography-mass spectrometry (GC-MS). The study’s findings reveal the existence of a vast number of phytochemicals, allowing for a comparison of the different accessions. Furthermore, a meticulous statistical analysis of this data using principal components analysis (PCA) and a heatmap, and hierarchical cluster analysis (HCA) may aid in providing more relevant information on C. roseus leaves for possible investigation of their metabolites in further scientific studies.
