Chemical Compositions of the n-hexane Fraction of Canna edulis Ker Gawl Rhizomes

Abstract

In this study, six compounds isolated from the n-hexane fraction of Canna edulis Ker Gawl rhizomes for the first time include 24-methylenecycloartane-3β-ol, sitoindoside I, citrulloside, 16β-hydro-19-al-ent-kauran-17-oic acid, daucosterol, and β-sitosterol. Spectroscopic methods as MS and NMR were used to elucidate their structures. Keywords: Canna edulis Ker Gawl, β-sitosterol, daucosterol, sitoindoside I, citrulloside, 24-methylenecycloartane-3β-ol, 16β-hydro-19-al-ent-kauran-17-oic acid. References [1] T. H. Vu, Q. U.
