| fumaric | <chemistry> Pertaining to, or derived from, fumitory (Fumaria officinalis). <chemistry> Fumaric acid, a widely occurring organic acid, exttracted from fumitory as a white crystallline substance, C2H2(CO2H)2, and produced artificially in many ways, as by the distillation of malic acid; boletic acid. It is found also in the lichen, Iceland moss, and hence was also called lichenic acid. Source: Websters Dictionary (01 Mar 1998) |
