Procedure
This material was recrystallized by dissolving in 300ml of heptane at reflux temperature. The clear solution was concentrated to 65ml, cooled to ambient temperature, and the crystallization product filtered. Washing with a little heptane, collection and drying gave 1.9g of material in well developed prismatic crystals of slightly green color (chlorophyll), and which on TLC (80% benzene, 20% ethyl acetate) analyzed as essentially hecogenin acetate with only a shade of the tigogenin acetate (corresponding to 0.95H and 0.05% approximately). M.p: 243°-244°C., Saponification gave hecogenin m.p. 262°-263°.
