The CHCI3 extract of the Mediterranean Bryozoan Myriapora truncata was shown to contain, in addition to the known cholest-7-en-3beta,5alfa,6beta-triol (1) ( 22E,24S)-24- methylcholesta-7,22-dien-3beta,5alfa,6beta-triol (3), three new sterols: (22E)-cholesta-7,22dien- 3beta,5alfa,6beta-trioI (2), (22E,24R)-24-methylcholesta-7,22dien-3beta,5alfa,6beta-triol (4), and (22E,24~)-24-ethylcholesta-7,22-dien-3beta,5alfa,6beta-triol (5), whose structures were elucidated on the basis of physico-chemical evidence. All the above compounds have been isolated as 3,6- diacetylderivatives.

Abstract
The CHCI3 extract of the Mediterranean Bryozoan Myriapora truncata was shown to contain, in addition to the known cholest-7-en-3beta,5alfa,6beta-triol (1) ( 22E,24S)-24- methylcholesta-7,22-dien-3beta,5alfa,6beta-triol (3), three new sterols: (22E)-cholesta-7,22dien- 3beta,5alfa,6beta-trioI (2), (22E,24R)-24-methylcholesta-7,22dien-3beta,5alfa,6beta-triol (4), and (22E,24~)-24-ethylcholesta-7,22-dien-3beta,5alfa,6beta-triol (5), whose structures were elucidated on the basis of physico-chemical evidence. All the above compounds have been isolated as 3,6- diacetylderivatives.File in questo prodotto:
