Diosgenin

/daɪˈɒsdʒənɪn/ noun

Definition

A steroid compound found primarily in yam plants, used as a starting material in the chemical synthesis of hormonal contraceptives and corticosteroids.

Etymology

From 'dioscorea' plus the chemical suffix '-genin' (a precursor molecule). Isolated in the 1930s, it became crucial to pharmaceutical chemistry after WWII.

Kelly Says

Diosgenin is the accidental hero of contraceptive history—yam-derived diosgenin was the chemical building block that let scientists synthesize the first birth control pills.
