摘要：
High-field H-1 and C-13 NMR spectroscopy has been used to characterize the fine structure of the cystocarpic and tetrasporic carrageenans from Iridaea undulosa. The proportion of different carrageenans from the kappa-family in cystocarpic samples were calculated. In the C-13 NMR spectra of the tetrasporic samples, twelve signals of approximately equal intensity were observed, indicating a nearly ''perfect'' lambda-structure.
