Abstract
From the rhizomes of Hypoxis nyasica, two monoglucosides having the same aglucones, nyasoside [1-(4′-hydroxyphenyl)-3-(4″-hydroxyphenyl)-1,4-pentadiene], were isolated. The structures were assigned by comparison of their spectroscopic data (and of the corresponding methyl and tetrahydromethyl derivatives with those of nyasoside (and tetrahydronyasoside).
