Gynostemma compressum is an endemic herbaceous species distributed in northwestern China. Here, we report the complete chloroplast (cp) genome sequence of G. compressum using Illumina pair-end sequencing. The circular complete cp genome of G. compressum was 157,959 bp in length and contained a large single copy region (86,809 bp), a small single copy region (18,560 bp) and two short inverted repeat (IRa and IRb) regions (26,295 bp). The cp genome encodes 133 genes including 87 protein-coding genes, 37 transfer RNA (tRNA) genes, 8 ribosomal RNA (rRNA) genes and 1 pseudogene. The maximum likelihood phylogenetic analysis showed that all the species of G. compressum formed a monophyletic clade and Gynostemma pentaphyllum was closely related to the genus Citrullus with strong bootstrap values.
