The title compound, stigmasta-5,22-dien-3beta-ol hemihydrate, C(29)H(48)O x 0.5H(2)O, previously thought to be the monohydrate, has two sterol molecules and one water molecule in the asymmetric unit. In both sterol molecules, the methyl group of the ethyl substituent at the end of the hydrocarbon chain is disordered over two sites.

Polyamine conjugates of stigmasterol
Steroids, 2012Three new polyamine conjugates with stigmasterol [(3β,22E)-stigmasta-5,22-dien-3-ol] were synthesized and subjected to basic antimicrobial and cytotoxic tests. The conjugate derived from spermine, (3β,22E)-stigmasta-5,22-dien-3-yl 4(12-amino-4,9-diaza-dodecylamino)-4-oxobutanoate (5c), displayed considerable antimicrobial activity on Staphylococcus ...

AbstractHydrogenations of stigmasterol over 5% Pd/C, 5% Ru/C, Pt, Raney Ni, Raney Co, Ni/kieselguhr, and tris(triphenylphosphine)chlororhodium catalysts and with diimide generated from hydrazine andp‐toluenesulfonylhydrazide were studied to determine the best conditons for the selective reduction of the Δ22 double bond.

Stigmasterol Removal by an Aerobic Treatment System
2023Stigmasterol is a phytosterol contained in kraft mill effluent that is able to increase over 100% after aerobic biological treatment. This compound can act as an endocrine disrupter as its structure is similar to that of cholesterol. Furthermore, stigmasterol contained in kraft mill effluent shows high toxicity (25-fold more than β-sitosterol) to ...

Biosynthesis of Stigmasterol in Tomato Fruits
Science, 1961The presence of stigmasterol in tomato fruits was demonstrated. Labeled mevalonic acid was incorporated into this sterol, while sodium acetate was not. The identity of the isolated product was established by rigorous purification to constant specific activity, melting point determinations, and infrared ...
