Complete 1H and 13C NMR assignments of four new steroidal glycosides from a gorgonian coral Junceella juncea

Magn Reson Chem. 2005 Mar;43(3):266-8. doi: 10.1002/mrc.1530.

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.
