![]() A bibliographic research allowed to establish a correlation between traditional medicine information of anti-inflammatory property of P. Compound 1 was extracted by maceration in EtOH 96° and it was isolated by using chromatographic techniques. Compound 1 is found to be the major component of the alcoholic extract of roots of Polygonum punctatum (Polygonaceae), a macrophyte native species of Paraguay with varied therapeutic applications like anti-inflammatory among others. The aim of this article is to provide full NMR spectra (1H 500 MHz, 13C 125.8 MHz) of stigmast-5-en-3-ol (1), whose other common names are: -sitosterol, -sitosterin, 22,23-dihydrostigmasterol, and IUPAC name: 17-(5-ethyl-6-methylheptan-2-yl)-10,13-dimethyl-2,3,4,7,8,9,11,12,14,15,16,17-dodecahydro-1-cyclopentaphenanthren-3-ol., and IUPAC name: The spectra set includes HMBC, HSQC and COSY studies.
