Biosynthesis of stigmasterol from sitosterol in Digitalis Lanata

Steroids, 1969
Abstract After administration of sitosterol-3-14C to a Digitalis lanata plant, radioactive stigmasterol was isolated by chromatography and shown to be radiochemically pure by crystallization to constant specific activity.

Semi‐synthesis of Several Stigmasterol Saponins

Chinese Journal of Chemistry, 2006
AbstractSeveral stigamasterol saponins were concisely synthesized. Namely, four monosaccharide (glucopyranose, galactopyranose, xylopyranose, 2‐acetamido‐2‐deoxy‐α‐D‐glucopyranose), lactopyranose and chacotriose were coupled with 3‐OH of stigmasterol. All the compounds were identified by NMR, IR and high resolusion MS.

Spatio-varietal differences in stigmasterol biosynthesis in tomato and overexpression of a sterol desaturase gene for enhanced stigmasterol production

In Vitro Cellular & Developmental Biology - Plant, 2016
Plant stigmasterol possesses many therapeutic properties, and it is used as one of the precursors for synthesis of synthetic progesterone. In this study, the stigmasterol content was analyzed in various plant parts of tomato (Solanum lycopersicum), and increased synthesis was attempted in tomato tissue culture cells.
