Abstract

Abstract:

A new aristololactam, aristololactam VII (1), was isolated from the root and rhizome of Asarum maximum Hemsl. On the basis of spectroscopic analysis, its structure was identified as 10-amino-7,8-dimethoxy-3,4-methylenedioxy-phenanthrene-1-carboxylic acid lactam.

Key words: Asarum maximum Hemsl., Asarum maximum Hemsl., Aristololactam VII, Aristololactam VII, 10-Amino-7,8-dimethoxy-3,4-methylenedioxy-phenanthrene-1-carboxylic acid lactam, 10-Amino-7,8-dimethoxy-3,4-methylenedioxy-phenanthrene-1-carboxylic acid lactam
