title: Chemical constituents from the seeds of Zanthoxylum alatum.
abstract: Chemical studies on the seeds of Zanthoxylum alatum Roxb. (Rutaceae) led to the isolation of two new phenolic constituents characterized as 3-methoxy-11-hydroxy-6,8-dimethylcarboxylate biphenyl (3) and 3,5,6,7-tetrahydroxy-3',4'-dimethoxyflavone-5-beta-D-xylopyranoside (6), along with the five known compounds, 1-methoxy-1,6,3-anthraquinone, 1-hydroxy-6,13-anthraquinone, 2-hydroxybenzoic acid, 2-hydroxy-4-methoxy benzoic acid, and stigmasta-5-en-3beta-D-glucopyranoside, on the basis of spectral data and chemical analyses.
