thumb|right|The chemical structure of yamogenin, a sapogenin found in [[fenugreek]]
Sapogenins are aglycones (non-saccharide moieties) of saponins, a large family of natural products. Sapogenins contain steroid or other triterpene frameworks as their key organic feature. Some steroidal sapogenins can serve as a practical starting point for the semisynthesis of particular steroid hormones.
