What's the difference between saponin and sarsaparillin?
Saponin
Definition:
(n.) A poisonous glucoside found in many plants, as in the root of soapwort (Saponaria), in the bark of soap bark (Quillaia), etc. It is extracted as a white amorphous powder, which occasions a soapy lather in solution, and produces a local anaesthesia. Formerly called also struthiin, quillaiin, senegin, polygalic acid, etc. By extension, any one of a group of related bodies of which saponin proper is the type.
Example Sentences:

(8) The effect of a preliminary hepatic washing with saline before liver fixation either by perfusion or immersion was compared to the effect of saponin, a membrane-permeabilizing agent, in order to ascertain which procedure is best to obtain a homogeneous distribution of albumin-containing hepatocytes in the hepatic lobule.
(9) Studying fiber bundles (less than 200-microns diameter) from guinea pig papillary muscles skinned with saponin and mechanically skinned single fibers from frog semitendinosus muscle, we find that calcium-induced force oscillations (observed in solutions containing low ethyleneglycol-bis(beta-aminoethylether)-N,N'-tetraacetic acid and pCa 7.0) are enhanced in magnitude and frequency by InsP3 at concentrations as low as 1 microM.

(14) Saponin-permeabilized polymorphonuclear leukocytes (PMNs) released beta-glucuronidase, a lysosomal enzyme, dose-dependently in response to cupric phenanthroline (CuPh), a mild oxidant, which catalyzes the formation of disulfide bridges.
