title: Molecular spectroscopic study of acid treated fenugreek seeds.
abstract: Fenugreek seeds were subjected to acid treatment in order to activate its surface. XRF indicated that there was no change in the level of metals and metal oxides as a result of the treatment. FTIR of the treated fenugreek showed no change in the characteristic bands and/or structure of the fenugreek. A shift in both OH and metal oxide bands suggest a role for metal, hydrated metal and metal oxide in fenugreek seed. Molecular modeling suggests that metal oxides such as Al16O24 offer its surface for the adsorption of gases. The interaction of gases with metal oxide is depending on the type of gas rather than the type of coordination. Finally results indicate that fenugreek could be used safely to control the level of gases in stomach.
