摘要

A species of the genus Glycyrrhiza, G. pallidiflora Maxim, growing in Jiangsu and Hebei Provices of China, has been little studied before on its chemical constituents. This paper reports the isolation and chemical elucidation of five compounds from this plant, one of them is a new compound named glypallichalcone (P-2). Their chemical structures were elucidated by means of chemical and spectrometric analysis (UV, IR, MS, 1HNMR and 13CNMR) and were first reported to be present in this plant. Glypallichalcone (P-2), was found to be 4-hydroxy-2,4'-dimethoxy-chalcone. The known compounds were identified to be 4'-O-methylcoumestrol (P-1), N-acetyl-glutamic acid (P-3), formononetin and beta-sitosterol (P-5).
