Chronic inflammation is involved in a number of diseases such as rheumatoid arthritis, psoriasis or ulcerative colitis. The most common treatment for chronic inflammatory diseases are nonsteroidal anti-inflammatory drugs (NSAIDs). Their long-term use, however, may cause a series of adverse effects. The goal of this research is to find plant based alternatives and novel compounds with the ability to improve classical treatment of chronical inflammatory diseases. [1]
The dichloromethane, methanol and water extracts of Albizia julibrissin DURAZZ. bark have been found active in an anti-inflammatory assay at 50μg/ml in LPS and IFNγ induced murine RAW 264.7 macrophages and microglial BV-2 cells. [2] After liquid-liquid extraction for fractionation of the active compounds, all 6 fractions showed inhibitory activity on NO production. However only the lipophilic fractions 1-3 did not interfere with cell viability, compared to cells treated with solvent control. Therefore, the reduced production of NO in cells treated with the polar fractions 4-6 is most likely due to cytotoxic effects.
Active components of the extracts and the active compounds of Albiziae cortex are investigated by LC-MS dereplication and isolation. Since the genus Albizia is known for triterpenoid saponins, saponins are expected among the active constituents. [3], [4]
