Abstract

Four new cholest‐type steroidal glycosides, junceellosides A–D, isolated from the EtOH/CH~2~Cl~2~ extracts of the South China Sea gorgonian coral Junceella juncea, were identified. Complete assignments of the ^1^H and ^13^C NMR chemical shifts for these compounds were achieved by means of one‐ and two‐dimensional NMR techniques, including ^1^H–^1^H COSY, HSQC, HMBC and NOESY spectra.
