Abstract:
Aim To study the chemical constituents of Ardisia punctata. Methods Compounds 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. Results Three 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-1,4-benzoquinone (3). Conclusion The three compounds are new1,4-benzoquinone derivatives.
