Title: New anthraquinones from the stem of Morinda citrifolia Linn. Author: Siddiqui BS, Sattar FA, Begum S, Gulzar T, Ahmad F. Journal: Nat Prod Res; 2006 Oct; 20(12):1136-44. PubMed ID: 17127668. Abstract: Studies on the chemical constituents of the stem of Morinda citrifolia, Linn. have led to the isolation of two new compounds, morindicinone (=2-hydroxy-1,8-dimethoxy-7-methoxymethylanthraquinone, 1) and morindicininone (=4-hydroxymethyl-1,3-dimethoxyanthraquinone, 2), as well as two known constituents, 2-hydroxyanthraquinone (3) and 2-methoxyanthraquinone (4). Their structures were elucidated by spectral analysis including 2D-NMR techniques.[Abstract] [Full Text] [Related] [New Search]
