Structurally, 21884-45-7 Rugulosin, (1S,1'S,2R,2'R,3S,3'S,9aR,9'aR)- 5H,6H-6,13a,5a,14-(1,2,3,4)Butanetetraylcycloocta(1,2-b:5,6-b')dinaphthalene-5,8,13,16(14H)-tetrone, 1,7,9,15,17,20-hexahydroxy-3,11-dimethyl-, (5aR-(5aR*,6S*,13aR*,14S*,17R*,18S*,19S*,20R*))- (C30H22O10) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 20.0, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 542.49 g/mol, it falls into the moderately-high-molecular-weight range. 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).
