With the parametrization of parton distribution functions (PDFs) of the proton by Soffer et al., we extend the valence quark contents to other octet baryons by utilizing SU(3) flavor symmetry. We find the method practically useful. Fragmentation functions (FFs) are further obtained through the phenomenological Gribov-Lipatov relation at the x→1 region. Our results are compared with different models, and these different predictions can be discriminated by upcoming experiments.
