The fragmentation pattern in electron-impact mass spectrometry has been established for the peracetylated methyl ester methyl glycoside derivative of N-acetylneuraminic acid. The resulting, data allow the interpretation of the mass spectrum of the corresponding derivative of a new sialic acid isolated from the starfish Distolasterias nipon which is shown to be 8-O-methyl-N-acetylneuraminic acid. 相似文献

Two compounds, nicotiflorin and rutin, are isolated and idenitified from flowers of Echinacea purpurea (L.) Moench., of the family Asteraceae, cultivated in Samara oblast. It is established that nicotiflorin (3-O-rutinoside campherol) is the dominant flavonoid of Echinacea purpurea; it is described along with rutin for the first time for this plant, cultivated in the Russian Federation and CIS countries. 相似文献
