Resin Glycosides. XVI. Marubajalapins I-VII, New Ether-Soluble Resin Glycosides from Pharbitis purpurea

Fifteen new resin glycosides, marubajalapins I-XV, were isolated from the jalapin fraction of the aerial part (leaves and stems) of Pharbitis purpurea. Among them, the structures of marubajalapins I-VII have been determined on the basis of chemical and spectral data. They are the first examples of j...

Zusammenfassung:	Fifteen new resin glycosides, marubajalapins I-XV, were isolated from the jalapin fraction of the aerial part (leaves and stems) of Pharbitis purpurea. Among them, the structures of marubajalapins I-VII have been determined on the basis of chemical and spectral data. They are the first examples of jalapins with operculinic acid E obtained previously as a minor glycosidic acid of the crude jalapin from Jalapae Braziliensis.
