However Green gram of Indian legumes was contained highest amount of bound hydrocyanide, the Black eye bean was contained lowest amount of bound hydrocyanide, in case of total cyanide the soybean, and pea-nut were contained highest amount of CN[-] and also Black eye bean was contained lowest amount of CN[-]
