Isofloridosides (1-O-alpha-D-galactopyranosylglycerol) and floridoside (2-O-alpha-D-galactopyranosylglycerol) were extracted from the red alga Porphyra umbilicalis (Linné) Kützing (Bangiales, Rhodophyta). Their separation was achieved by HPLC (NH(2) P50 column) after successive purification of the crude extract by ion-exchange chromatography and HPLC (Sugar-Pak TM1 column). 1D and 2D NMR spectroscopy experiments allowed to completely assign the (1)H and (13)C spectra of D-isofloridoside.
异弗罗里糖苷(1-O-α-D-吡喃半乳糖基甘油)和弗罗里糖苷(2-O-α-D-吡喃半乳糖基甘油)是从红藻紫菜(林奈)库茨(红毛菜纲,红藻门)中提取的。在通过离子交换色谱法和高效液相色谱法(Sugar-Pak TM1柱)对粗提取物进行连续纯化后,通过高效液相色谱法(NH(2) P50柱)实现了它们的分离。一维和二维核磁共振光谱实验能够完全确定D-异弗罗里糖苷的氢谱和碳谱。
