The molecular framework of (2S,3S,4S,5R,6R)-5-(((2S,3R,4S,5R,6R)-4,5-Dihydroxy-6-(hydroxymethyl)-3-(((2S,3R,4R,5R,6S)-3,4,5-trihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)tetrahydro-2H-pyran-2-yl)oxy)-3,4-dihydroxy-6-(((3S,4S,4aR,6aR,6bS,8aR,9R,12aS,14aR,14bR)-9-(((R)-5-hydroxy-6-methyl-4-oxo-3,4-dihydro-2H-pyran-2-yl)oxy)-4-(hydroxymethyl)-4,6a,6b,8a,11,11,14b-heptamethyl-1,2,3,4,4a,5,6,6a,6b,7,8,8a,9,10,11,12,12a,14,14a,14b-icosahydropicen-3-yl)oxy)tetrahydro-2H-pyran-2-carboxylic acid (C54H84O21) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
