Anthraquinones from the roots of Prismatomeris tetrandra

Chem Pharm Bull (Tokyo). 2005 Oct;53(10):1330-2. doi: 10.1248/cpb.53.1330.

Abstract

Three new anthraquinones, 1-hydroxy-2,3-dimethoxy-7-methyl-9,10-anthraquinone, 1,3-dihydroxy-5,6-dimethoxy-2-methyl-9,10-anthraquinone, and 3-hydroxy-1,5,6-trimethoxy-2-methyl-9,10-anthraquinone, along with five known anthraquinones were isolated from the roots of Prismatomeris tetrandra. Their structures were determined on the basis of spectroscopic data.
