Sapogenins are the
aglycones, or non-
saccharide, portions of the family of natural products known as
saponins. Sapogenins contain
steroid or other
triterpene frameworks as their key organic feature. For example, steroidal sapogenins like tiggenin, neogitogenin, and tokorogenin have been isolated from the
tubers of
Chlorophytum arundinacelum. Some steroidal sapogenins can serve as a practical starting point for the
semisynthesis of particular
steroid hormones.
