2.11.3 Glycosidal Resins
The Jalap and Scammony are the two well
known examples of the glycosidal resins occurring in the natural
products, namely: Jalap—from the dried tuberous root of Exogonium
purga (Hayne) Lindl. (E. jalap Baill., Ipomea purga Hayne),
belonging to family Convolvulaceae; Scammony—from the dried roots of Convulvulus
scammonia L., belonging to family Convolvulaceae. The glycosidal nature
of these resins are evidenced by the presence of sugars, such as glucose,
rhamnose and fucose on hydrolysis.
