Cytotoxic Butanolides from the Stem Bark of Formosan Lindera communis

摘要: Two new butanolides, lincomolide A (1), B (2), along with seven known compounds, isolinderanolide E, sepesteonol, beta-sitosterol, beta-sitosterol-beta-glucoside, tetradecane, nonanoic acid and decanol, were isolated from the chloroform-soluble portion of stem bark Lindera communis. Compound 1 showed cytotoxicity against P-388, KB16 A549, 2 exhibited P-388 cancer cell lines. Moreover, marginal activity HT-29, KB16, A549 HT-29 The structures these compounds determined by spectral analyses.
