“…Conventionally, sapogenins and saponins of Agave were detected using 10e50% sulfuric acid followed by heating at 100 C (Blunden et al, 1980a;Sharma et al, 2012;Yi et al, 1989), Libermann-Burchard reagent (da Silva et al, 2006;Ding et al, 1993;Yu et al, 2011) (da Silva et al, 2002(da Silva et al, , 2005da Silva and Parente, 2007), respectively. Ghoghari and Rajani (2006) have developed an HPTLC method for the determination of hecogenin (1) in the leaf powder of Agave americana. The mobile phase used for the analysis was toluene/ ethyl acetate/methanol (6:1:0.8).…”
