sarsasapogenin and dextrose. It is considered as the only definite saponin glycoside
in Jamaica sarsaparilla, which also contains sarsapic acid (a crystalline dicarboxylic
acid), dextrose, fatty acids, sitosterol-D-glycoside, resin, etc. Like other drugs
containing saponins it possesses hemolytic properties of red blood corpuscles just

Cruz sarsaparilla has the highest hemolytic index, Jamaica rather lower and Honduras
much lower. The drug yields about 4-10 % of ash.
