title: Two New Glucosides from Hypoxis obtusa: Obtuside A and Obtuside B1,5.
abstract: From the rhizomes of HYPOXIS OBTUSA two monoglucosides having the same aglycone as hypoxoside, 1-(3',4'- dihydroxyphenyl)-5-(3'',4''-dihydroxyphenyl)-1-pen-ten-4-yne, have been obtained. By methylation followed by hydrogenation they have been transformed into the same compound, 1-(3'-methoxy-4'- O-beta- D-glucopyranosyl-phenyl)-5-(3''-4''-dimethoxyphenyl)-pentane, likewise obtainable through partial hydrolysis of hypoxoside.
