Abstract
|
|
|
|
A chemical examination of the stems of Sapium japonicum PAX et HOFFM (Euphorbiaceae) has led to the isolation of seven phenolic compounds. On the basis of UV, IR, MS, and NMR spectral data and the chemical reaction, the structures of these compounds were identified as gallic acid (1), ellagic acid (2), 3,3’-di-O-methylellagic acid (3),$-O-(β-D-xylopyranosyl)-3,3 acid (4),$-O-(α-D-arobinofuranosyl)-3,3 acid (5), isoquercitrin (6), and geraniin (7).
