Abstract:
AIMTo study the chemical constituents of Ardisia punctata.
METHODSCompounds were separated with a combination of multi-chromatography. Their chemical structures were determined on the basis of spectral analysis and single crystal X-ray diffraction.
RESULTSThree compounds were isolated from chloroform extract of the roots of Ardisia punctata. Their structures were elucidated as 2-tridecyl-3-[(2-tridecyl-3-acetoxy-4-methoxy-6-hydroxy) -phenyl]-6-methoxy-1, 4-benzoquinone (1), 2-tridecyl-3-[(2-tridecyl-4,6-dihydroxy) -phenyl]-6-methoxy-1,4-benzoquinone (2) and 2-tridecyl-3-[(2-pentadecyl-4,6-dihydroxyl) -phenyl]-6-methoxy-,4-benzoquinone (3).
CONCLUSIONThe three compounds are new 1,4-benzoquinone derivatives.
