Marine sterols. 18. Isolation and structure of four novel oxygeneted sterols from a gorgonian coral Melithaea ocracea

Autor: Fuyuko Kanda, Masaru Kobayashi

Publikováno v: Journal of the Chemical Society, Perkin Transactions 1. :1177

Four new marine polyhydroxysterols, melithasterols A–D (1a–1d), were isolated from a gorgonian coral Melithaea ocracea of the Okinawa Islands. The 1H and 13C NMR spectral analyses indicated them to be cholestane and 24-methylcholestane derivative
