COLLANTES DIAZ, Ingrit Elida  y  CONDOR CUYUBAMBA, Elena Alicia. Contribution to the phytochemical study of tubers from Ullucus tuberosus caldas. Rev. Soc. Quím. Perú [online]. 2020, vol.86, n.2, pp.105-111. ISSN 1810-634X.  http://dx.doi.org/10.37761/rsqp.v86i2.280.

This paper describes the phytochemical analysis of the lyophilized juice of the tubers from Ullucus tuberosus, native of the Andean region, which are used in Peruvian gastronomy. From organic solvents extraction and separation by transesterification of fatty acids and chromatography methods, the presence of palmitic acid methyl ester and stigmasterol and spinasterol steroids in the species under study were first identified, these compounds were identified by analysis of its nuclear magnetic resonance spectra hydrogen-1 and carbon-13.

Palabras clave : Ullucus tuberosus; tuber; stigmasterol; spinasterol.
