Abstract:
Two of the main classes of oxyphytosterols (7-keto and epoxides) were synthesized from sitosterol and campesterol and given
to mesenteric duct-cannulated adult male rats. Lymph was collected during 24 h and was analyzed for oxysterols. The results
showed that the lymphatic recovery of the phytosterol oxides was low: 4.7% of the given dose for epoxy derivatives and 1.5%
for 7-keto compounds. The campesterol oxides presented a better absorption than the sitosterol oxides. During the process
of absorption’ the epoxyphytostanols were also partly transformed in campestanetriol and stigmastanetriol.
