Recently, we identified that GIPC is hydrolyzed to phytoceramide 1-phosphate (PC1P) by an uncharacterized phospholipase D activity following homogenization of certain plant tissues. We now developed methods for isolation of GIPC and PC1P from plant tissues and characterized their chemical stabilities. Hydrophilic solvents, namely a lower layer of a mixed solvent system consisting of isopropanol/hexane/water (55:20:25, v/v/v) was efficient solvent for extraction and eluent in column chromatography. GIPC was isolated by Sephadex column chromatography followed by TLC. A conventional method, such as the Bligh and Dyer method, was applicable for PC1P extraction. Specifically, PC1P was isolated by TLC following mild alkali treatment of lipid extracts of plants. The yields of GIPC and PC1P in our methods were both around 50-70%. We found that PC1P is tolerant against heat (up to 125 °C), strong acid (up to 10 M HCl), and mild alkali (0.1 M KOH). In contrast, significant degradation of GIPC occurred at 100 °C and 1.0 M HCl treatment, suggesting the instability of the inositol glycan moiety in these conditions. These data will be useful for further biochemical and nutritional studies on these sphingolipids.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier","subitem_publisher_language":"en"}]},"item_10001_rights_15":{"attribute_name":"権利情報","attribute_value_mlt":[{"subitem_rights":"© 2020.
