                                Diosgenin, a key steroidal sapogenin, is predominantly derived from the tubers of certain species of wild yam (*Dioscorea*) and the seeds of fenugreek (*Trigonella foenum-graecum*), and has been used since the 1930s as a crucial precursor for pharmaceutical production.
