Ma has been considered to have the effect of \u201ctonifying the kidney and strengthening the yang,\u201d and is used for the prevention and treatment of diseases such as impotence, female infertility, lumbago and senile constipation. Polysaccharides and small molecules of acteoside are the main chemical compounds co-existing in <jats:italic>Cistanche deserticola<\/jats:italic> Y. C.

Male Sprague\u2013Dawley rats were randomly divided into Control group, unprocessed Cistanche polysaccharide group (UCP group) and wine-processed Cistanche polysaccharide group (WCP group). After 21\u202fdays of intervention with unprocessed Cistanche polysaccharides and wine-processed Cistanche polysaccharides, rats were given 100\u202fmg\/kg of acteoside on day 22. Acteoside and its associated metabolites pharmacokinetically studied were analysed using UPLC-QqQ-MS, and the composition of short-chain fatty acids (SCFAs) in excrement was measured using the technique of GC\u2013MS.
