Lyratin D, A New 4-Hydroxyisoflavan from the Whole Plant of Solanum lyratum Thunb

초록

A new 4-hydroxyisoflavan, named lyratin D (1), was isolated from the whole plant of Solanum lyratum Thunb. Its structure and absolute configuration were elucidated through a comprehensive analysis of its HR-ESIMS, 1D and 2D NMR, and circular dichroism spectroscopy data. Compound 1 was then assessed for its cytotoxic effects on RAW264.7 murine macrophage cells, and its antioxidant activity was evaluated through DPPH assay.
