Structural Determination of Saponins from Mungbean Sprouts by Tandem Mass Spectrometry
Saponins are glycosides that commonly occur in higher plants. Saponins are classified into triterpene and steroid groups; the aglycone usually has an oleanane, ursane, or dammarane skeleton. The sugars encountered in saponins are hexoses (including glucose, galactose, mannose, and 6-deoxyhexoses), pentoses, uronic acids, or amino sugars. Sugars may be linked to the sapogenin at one or two glycosylation sites, giving corresponding monodesmosidic or bidesmosidic saponins, respectively.
