Fenusterols® is the saponin rich fraction obtained from Fenugreek seeds. Saponins are complex glycosidic compounds present in a diverse array of edible and inedible plants1. Each saponin consists of a sapogenin which constitutes the aglycon moiety of the molecule, and a sugar. The sapogenin may be a steroid or a triterpene and the sugar moiety may be glucose, galactose, pentose or a methylpentose2 (Figure 1).
