Biologically active glycosides from asteroidea, III. Steroid oligoglycosides from the starfishAcanthaster planci L., 2. Structures of two newly characterized genuine sapogenins and an oligoglycoside sulfate
From the whole bodies of Acanthaster planciL. a genuineoligoglycoside which is an unstable type 20-hydroxycholesten-23-one glycosidesulfate has been isolated in large quantities. Apart from the known 3β,6α-dihydroxy-5α-pregn-9(11)-en-20-one (1) two new genuine aglycones were isolated by enzymatic hydrolysis of the crude oligoglycoside fraction for the first time. The structures were identified by
