title: A novel monogalactosylacylglycerol with inhibitory effect on platelet aggregation from the cyanophyceae Oscillatoria rosea.
abstract: (2S)-1-O-Palmitoyl-3-O-beta-D-galactopyranosylglycerol, isolated from the marine alga Oscillatoria rosea, inhibited platelet aggregation induced by U46619, a thromboxane A2 analogue. Its structure was elucidated by spectroscopic analysis and chemical evidence.
