| chelidonic acid | Chelidonic acid | |
| fr 901464 | A spiro-epoxide with potent anticancer activity that lowers the mRNA levels of oncogenes and tumour supressor genes. It is isolated from Pseudomonas sp. no.2663. | FR901464 |
| fulvoplumierin | Fulvoplumierin | |
| ligstroside | 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 4-hydroxyphenethyl ester (the 2S,3E,4S stereoisomer). An important phenolic compound present in olive cultivars. | ligstroside |
| oleuropein | 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). The most important phenolic compound present in olive cultivars. | oleuropein |
| oleuropein aglycone | A secoiridoid 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 carboxylic acid moiety of the carboxymethyl substituent has been converted to the corresponding 3,4-dihydroxyphenethyl ester (the 2R,3E,4S stereoisomer). The most important phenolic compound present in olive cultivars. | oleuropein aglycone |
| secologanin | An iridoid monoterpenoid that is acetaldehyde in which on of the hydrogens of the methyl group has been replaced by a 2-(beta-D-glucopyranosyloxy)-3,4-dihydro-2H-pyran-4-yl group which is substituted at positions 3 and 5 by a vinyl and a methoxycarbonyl group, respectively (the 2S,3R,4S stereoisomer). | (-)-secologanin |
| secoxyloganin | A secoiridoid glycoside that is [(2R,3R,4S)-2-hydroxy-5-(methoxycarbonyl)-3-vinyl-3,4-dihydro-2H-pyran-4-yl]acetic acid in which the anometric hydroxy group has been converted to the corresponding beta-D-glucoside. It has been isolated from several plant species and exhibits antioxidant and anti-allergic properties. | secoxyloganin |
| zincophorin | griseochelin |
