A 1H n.m.r. method based on the chemical shift of the 10-methyl protons is used to locate the position of the glucose residue in marthasterone 6α-glucoside, which is characterised as its penta-acetate, 3β-acetoxy-23-oxo-5α-cholesta-9(11),24-dien-6α-yl tetra-O-acetyl-β-D-glucoside (20). The 3β- and 6α-tetra-O-acetylglucosides of several model 5α-steroids are used to establish chemical shift relationships.

Starfish saponins—XI. Isolation and partial characterization of the saponins from the starfish Marthasterias glacialis
The saponin mixture isolated from Marthasterias glacialis was resolved through a series of chromatographic steps into four principal individual components, named marthasteroside A 1, A 2, B and C, which contained the aglycone thornastrol A and six sugar units. Expand
Studies on Steroid Metabolism in the Echinoderm Asterias Rubens
Since the pioneering work of Bergmann1 on the sterol composition of marine invertebrates, it has been apparent that the echinoderm classes Asteroidea (starfish) and Holothuroidea (sea cucumber)Expand
Synthesis of the sulfates derived from 5α-cholestane-3β, 6α-diol
Abstract Three new steroid sulfates—3β-hydroxy-5α-cholestan-6α-yl sulfate, 6α-hydroxy-5α-cholestan-3β-yl sulfate, and 5α-cholestan-3β, 6α-diyl disulfate—were synthesized. For the syntheses of the keyExpand

Saponins, complex water soluble compounds composed of a carbohydrate moiety attached to a steroid or triterpenoid aglycone, have been isolated from a great number of terrestrial plants, but are uncommon animal constituents. Expand
The identification and characterization of a new c1903 steroid metabolite in the eat ventral prostate: 5α-androstane-3β, 6α, 17β-triol
The 6 alpha- and 7 alpha-triols were found to possess no androgenic activity when tested by the ventral prostatic growth bioassay in the castrate rat, and a chemical synthesis of this triol has been accomplished. Expand
Metabolism of radiotestosterone to 3 beta,6 alpha- and 3 beta,7 alpha-dihydroxy 5 alpha-steroids by rat ventral, canine and human prostate in organ culture.
The 3 beta-hydroxy-5 alpha-androstane configuration of the identified C19O3-metabolites supports a pathway of prostatic and epididymal testosterone disposition which effects activation by 5 alpha-reductase and inactivation and egress by the coupled 5alpha-3-oxosteroid reductase/3 beta-Hydroxysteroid hydroxylase reactions.
