A reinvestigation of the exts. of the starfish A. pectinifera has led to the isolation of a novel asterosaponin pectinioside G (I) along with the already reported pectiniosides A, D, and acanthaglycoside C. The exts. contained asterosaponin P-1, previously isolated as sodium salt from Patiria pectinifera and Oreaster reticulatus, and now isolated also as tyramonium salt, and 5 highly hydroxylated steroids, among which I is new.

Abstract
A reinvestigation of the exts. of the starfish A. pectinifera has led to the isolation of a novel asterosaponin pectinioside G (I) along with the already reported pectiniosides A, D, and acanthaglycoside C. The exts. contained asterosaponin P-1, previously isolated as sodium salt from Patiria pectinifera and Oreaster reticulatus, and now isolated also as tyramonium salt, and 5 highly hydroxylated steroids, among which I is new.File in questo prodotto:
