Abstract:
A composition of matter is provided comprising a crystalline saponin-containing complex, wherein said crystalline complex is derived from a steroidal-saponin-containing plant material. Said crystalline complex is derived from a saponin-containing plant material by forming a mixture comprising saponin-containing aqueous plant extract solids and a mixture comprising methanol, acetone and water in a volume ratio of about 0. 1-20:0. 1-20:1. 0, and allowing the solution to stand at ambient temperature and pressure for a period of time sufficient to form the crystalline saponin-containing complex while plant fats and non-saponin carbohydrates remain substantially in solution.
