摘要：

The chemical structure of carrageenans produced by the gametophytic and tetrasporophytic life cycle phases of Gigartina pistillata has been determined by permethylation analysis, IR and C-13 NMR spectroscopies. The chemistry of the galactans varies according to the biological phases of the plant, the gametophytic alga produces heterogeneous kappa-iota type carrageenan containing minor amounts of v-carrabiose. The tetrasporophytic alga synthesizes a complex sulfated galactan composed of lambda-, xi-, pi -carrabioses and sulfated carrabioses containing 3-linked galactopyranose 2,6-disulfate.
