A secoiridoid glycoside that is the methyl ester of 3,4-dihydro-2H-pyran-5-carboxylic acid which is substituted at positions 2, 3, and 4 by hydroxy, ethylidene, and carboxymethyl groups, respectively and in which the anomeric hydroxy group at position 2 has been converted into its beta-D-glucoside and the carboxylic acid moiety of the carboxymethyl substituent has been converted to the corresponding 3,4-dihydroxyphenethyl ester (the 2S,3E,4S stereoisomer).
