Phytochemical profile, in vitro bioaccessibility, and anticancer potential of golden root (Rhodiola rosea L.) extracts

•Extract type affects the profile, stability and bioaccessibility of R.rosea compounds.•Phytochemicals from the extracts were more bioaccessible than from the plant material.•The highest bioaccessibility was found for the 70% ethanolic dry extract.•The dried extracts were characterized by cancer-specific cytotoxic activity.•Caco-2 and HT-29 cells' viability was effectively reduced by the golden root extracts.
