Abstrakt: Hibiscus mutabilis L. is a Traditional Chinese Medicinal plant of significant value. However, there has been limited research focusing specifically on its flowers. In this study, we report the isolation of one novel and nine known flavonoids from the flowers of H. mutabilis L. The structures of these compounds were elucidated using chemical and comprehensive spectral analysis, involving 1D, 2D NMR, and HRESIMS. The novel compound was further evaluated for its anti-inflammatory and cytotoxic activities using in vitro assays on RAW264.7 cells. Compound 1 at the concentration of 6.25 μM significantly inhibited the production of NO and TNF-α induced by LPS in RAW264.7 cells, exhibiting superior efficacy compared to the positive control dexamethasone, thus indicating its potential as an anti-inflammatory drug candidate.
