Abstract

The mono- and oligosaccharide composition of 2 different var. of groundnut was determined. 70% alcohol was used for extraction of mono- and oligosaccharides. Total monosaccharides constituted 5.08 and 5.00%, and were identified as D-glucose (2.89 and 2.88%) and D-fructose (2.19 and 2.11%); while total oligosaccharides amounted only to 3.23 and 3.38% of flour solids, respectively for the 2 var., and were identified as sucrose, 0.91 and 0.95%; raffinose, 0.94 and 1.06%; stachyose, 1.04 and 0.51%; and verbascose, 0.2 and 0.38%. Final identification of the sugars was achieved by GLC as their trimethylsilyl derivatives. In addition, one of the var. Nambyquarae (hybrid peanut) also contained ajugose, 0.48%. The 2 var. are unusual in that they contain a high proportion of free monosaccharides. [See also FSTA (1976) 8 2J259.]
