Previously, we found an unidentified sphingolipid in cabbage, and determined it as phytoceramide 1-phosphate (PC1P). PC1P is found to be produced from glycosylinositol phosphoceramide (GIPC) by the action of phospholipase D (PLD) activity. Although GIPC is abundant sphingolipid, especially in cruciferous vegetables, amount of daily intake, digestibility and nutritional activity of GIPC are not well understood. Here, we investigated amounts of GIPC and PC1P in vegetables. GIPC was found in all vegetables examined (13 kinds) at levels 3-20mg/100g (wet weight). On the other hand, PC1P was present in limited vegetables which show higher GIPC-PLD activity, such as inner cabbage leaves (5.2mg/100g). Because PC1P is formed during homogenization by activated GIPC-PLD, level of PC1P in boiled cabbage leaves was very low. Although digestibility of GIPC is unknown at present, a portion of dietary GIPC is considered to be converted to PC1P during mastication by plant-derived GIPC-PLD activity in some vegetables.
