**4. Conclusions**

This current study used the Illumina HiSeq 2500 platform to obtain the first complete chloroplast sequences of four medicinal Capparaceae species: *C. farinosa*, *C. glandulosa*, *M. crassifolia* and *M. oblongifolia*. The four species are divided into two groups: *C. farinosa* and *C. glandulosa* belong to the tribe Cadabeae; *M. crassifolia* and *M. oblongifolia* belong to the tribe Maerueae. This study can be used to accurately identify species during different medicinal uses based on their plastid genome.
