In: Agricultural and Biological ChemistrySummary: Se analizo la composicion de metabolitos de estres de trozos de raices deterioradas fisiologica y microbiologicamente de yuca var. Golden Yellow, Hawaiian-5 y Okinawa mediante cromatografia de gases y espectrometria de masa. Los metabolitos de estres se clasificaron por cromatografia de masa en 2 grupos: 4 esteroides y mas de 20 diterpenoides. Es muy factible que el constituyente principal, con formula molecular C20H28O3, sea el principal componente amargo de raices de yuca despues de su deterioracion fisiologica y microbiana; el segundo constituyente principal tenia la formula molecular C2OH3OO3. (CIAT)Summary: Chips of physiologically and microbially damaged roots of cassava var. Golden Yellow, Hawaiian-5, and Okinawa were analyzed for stress metabolite composition using gas chromatography and mass spectrometry. The stress metabolites were classified into 2 groups by mass chromatography: 4 steroids and more than 20 diterpenoids. The major component with a molecular formula C20H28O3 is most likely to be the principal bitter constituent in cassava roots after physiological and microbial deterioration; the 2nd major component had the molecular formula C2OH3OO3.
