摘要	Chemical investigation of the ethanol extract of the whole plant of Megacodon stylophorus led to the isolation and identification of two new secohopane triterpenoids, 2,3-seco-22(29)-hopene-2-carboxyl-3-aldehyde (1) and 2,3-seco-4(23),22 (29)-hopene-2-carboxyl-3-aldehyde (2), along with 10 known compounds, 3-12. All the isolates were reported from this plant for the first time. The structures of compounds 1 and 2 were determined by detailed analysis of their spectral data including 1D and 2D NMR. In addition, compound 1 was further analyzed by X-ray crystallography. Compounds 1-3 were evaluated for their in vitro anti-proliferative activities on HeLa, MCF-7, and Hep-G2 tumor cell lines. Compound 2 was active against the three cell lines with IC50 values of 3.6, 7.5, and 13.6 mu M, respectively, while compound 1 exhibited cytotoxicity on MCF-7 (IC50 14.0 mu M) and HeLa (IC50 18.2 mu M) cell lines. Antimicrobial activities of compounds 1-2 (minimum inhibitory concentration values in the range of 3.12-12.50 mg/mL) were also observed.; Chemical investigation of the ethanol extract of the whole plant of Megacodon stylophorus led to the isolation and identification of two new secohopane triterpenoids, 2,3-seco-22(29)-hopene-2-carboxyl-3-aldehyde (1) and 2,3-seco-4(23),22 (29)-hopene-2-carboxyl-3-aldehyde (2), along with 10 known compounds, 3-12.
