Cytotoxic Activity of Saponins and Sapogenins Isolated from Chenopodium quinoa Willd. in Cancer Cell Lines

Figure 7

(a) Chromatogram of white and red quinoa to determine the presence of saponins using a Liebermann–Burchard reagent. (b) The presence of a pink-violet stain in the first line and a violet stain in the second one indicates the presence of triterpenoid saponins. In ultraviolet light, at 366 nm, the saponins cannot be observed. (c) Chromatogram comparing the synthetic sapogenins, A: ursolic acid, B: hederagenin, and C: oleanolic acid, to the sapogenin samples from D: red quinoa and E: white quinoa after applying the Liebermann–Burchard reaction.
