| Popis: | Phytochemical investigation of methanolic extracts from the so far unstudied plant species Ixora cibdela Craib (Rubiaceae) led to the isolation and identification of an uncommon and novel fatty acid and the related methyl ester named as cibdelin A and cibdelin B. Additionally, the five known iridoid glucosides 11-methylixoside, shanzhiside, mussaenosidic acid, geniposidic acid, and apodanthoside together with the proanthocyanidin cinnamtannin B-1 were isolated from the root bark, as well as the lignan dihydrocubebin and the two coumarins scopoletin and isofraxidin from the stem bark extract. The structures of all isolated compounds were elucidated from 1D and 2D Nuclear Magnetic Resonance (NMR) spectroscopy. The results are discussed briefly in biological context. |
