A color reaction of steroid aglycones of the spirostan series with sulfuric acid solutions

Abstract

Thus, the most intense maximum with ~ = 12'10 s is observed in the reactlon of diosgenin with 96% acid at 60=C for 30 min, while c486 reaches its maximum value, of 23'10 ~, under the conditions of the reaction of diosgenin with a 72% aqueous solution of the acid in the presence of catalytic amounts (0.0001%) of Fe(III). The coloration develops at 50=C in 60… (More)
