AB  - Rauvolfia tetraphylla L. (1753) is an important medicinal species of Apocynaceae, widely used for its rich indole alkaloids and related bioactive compounds. We report the first complete chloroplast genome of R. tetraphylla. The genome exhibits a typical circular quadripartite structure of 155,667 bp, with an overall GC content of 37.8%. The genome comprises a large single-copy (LSC) region of 86,332 bp, a small single-copy (SSC) region of 17,853 bp, and a pair of inverted repeat (IR) regions of 25,741 bp each. A total of 130 unique genes are identified, including 85 protein-coding genes, 37 tRNA genes, and eight rRNA genes. Phylogenetic analysis strongly supports the close relationships among Rauvolfia species and indicates that R. tetraphylla represents an early-diverging lineage within the genus. Overall, this study enhances our understanding of the chloroplast genome characteristics and evolutionary history of R. tetraphylla and related taxa.
