Abstract.  (22R,23R)-22,23-dihydroxystigmast-4-en-3-one, (22R,23R)-22,23-dihydroxystigmast-4-en-3,6-dione, (22R,23R)-3β,5α,6β,22,23-pentahydroxystigmastane, (22R,23R)-5α,6α-oxido-3β,22,23-trihydroxystigmastane, (22R,23R)-5β,6β-oxido-3β,22,23-trihydroxystigmastane, and (22R,23R)-3β,6β,22,23-tetrahydroxystigmast-4-ene were synthesized. Their cytotoxicities were comparatively studied using the MCF-7 line of carcinoma cells of human mammary gland and cells of human hepatoma of the Hep G2 line.
