Resin glycosides from Convolvulaceae plants [PDF]

open access: yesJournal of Natural Medicines, 2017
Resin glycosides are well known as purgative ingredients, which are characteristic of certain crude drugs such as Mexican Scammony Radix, Orizabae Tuber, and Jalapae Tuber, all of which originate from Convolvulaceae plants. Depending on their solubility in ether, these are roughly classified into two groups-jalapin (soluble) and convolvulin (insoluble).
