Helicid, ein β‐Allopyranosid aus <i>Helicia erratica</i> Hook

Abstract

Helicid, a β‐Allopyranoside from Helicia erratica Hook Helicid ( 1 ), C 13 H 16 O 7 , was isolated from the seed of Helicia erratica Hook ( Proteaceae ). Its constitution and configuration was determined by proton and carbon‐13 NMR spectroscopy to be 4‐formylphenyl β‐allopyranoside. Thus, acidic hydrolysis of helicid yields 4‐hydroxybenzal‐dehyde and allose.
