Chlorophytum laxum R. Br.

From the methanol extract of the leaves of Chlorophytum laxum R. Br. (Athericaceae), a new (1) and two known (2, 3) derivatives of furancarboxaldehyde, and a derivative of anthraquinone (4) were isolated by various chromatography methods. Their structures were elucidated as 5- (ethoxymethyl)-2-furancarboxaldehyde (1), 5-hydroxymethyl-2-furancarboxaldehyde (2) and cirsiumaldehyde (3) and 1,5-dihydroxy-3-hydroxymethylanthraquinone (4) by analyses of the NMR (1D-, 2D-NMR), EI-MS and ESI-MS spectra. This is the first report of 2, 3, and 4 from C. laxum.
