title: Structural determination of kochiosides A-C, new steroidal glucosides from Kochia prostrata, by 1D and 2D NMR spectroscopy.
abstract: Kochiosides A-C, three new steroidal glucosides, have been isolated from the ethyl acetate fraction of Kochia prostrata and their structures assigned from its (1)H and (13)C NMR spectra, DEPT and by 2D COSY, NOESY, HMQC and HMBC experiments.
