摘要：

The quantitative heteroside distribution in Porphyra columbina Montagne and Bangia atropurpurea (Roth) C. Agardh (Bangiales, Rhodophyta) has been measured using C-13-nuclear magnetic resonance spectroscopy and gas-liquid chromatography. In P. columbina, floridoside and both D- and L-isofloridoside were recorded, with concentrations Of L-isofloridoside exceeding those of floridoside. All three compounds were also measured in B. atropurpurea. Marked changes in the relative amounts of the heterosides were recorded throughout the season. The role Of L-isofloridoside in the osmotic acclimation of P. columbina has been demonstrated.
