Application

Stigmasterol was used as a reference standard in determination of phytosterols in dietary supplements by gas chromatography and in frozen leaf samples of Arabidopsis thaliana by GC/MS.

Biochem/physiol Actions

Stigmasterol is a phytosterol with chemical structure similar to cholesterol. It exhibits anti-cancer, anti-pyretic, anti-inflammatory and immune-modulating effects. Stigmasterol decreases the expression of matrix metalloproteinases and reduced the degradation of cartilage in osteoarthritic rabbits.

Preparation Note

Stigmasterol yields clear, colorless solution in chloroform at 50 mg/ml.

Upon inoculation with pathogenic microbes, plants induce an array of metabolic changes that potentially contribute to induced resistance or even enhance susceptibility.
