Boron nuclei in cosmic rays (CRs) are believed to be mainly produced by the fragmentation of heavier nuclei, such as carbon and oxygen, via collisions with the interstellar matter. Therefore, the boron-to-carbon flux ratio (B/C) and the boron-to-oxygen flux ratio (B/O) are very essential probes of the CR propagation. With a large geometric factor and a good charge resolution, the DArk Matter Particle Explorer (DAMPE), is expected to extend the measurement of B/C and B/O up to a few TeV/n energies. In this contribution, the direct measurements of B/C and B/O in the energy range from 10 GeV/n to 5.6 TeV/n with six years of data collected by DAMPE are presented.
