A New Irregular Phenylpropanoid fromApollonias barbujana
摘要:
In addition to the known compounds (±)-threo-guaiacylglycerol and the phenethyl alcohols, 3-methoxy-4-dihydroxyphenethyl alcohol and 3,4-dimethoxyphenethyl alcohol, a new irregular phenylpropanoid 2-(3-methoxy-4-hydroxyphenyl)-1,3-propanediol was isolated from the ethanolic extract of the leaves of Apollonias barbujana (Lauraceae). Their structures were elucidated on the basis of spectroscopic methods and chemical transformations.
Water-soluble constituents of caraway: aromatic compound, aromatic compound glucoside and glucides
摘要:
From the water-soluble portion of the methanolic extract of caraway (fruit of Carum carvi L.), an aromatic compound, an aromatic compound glucoside and a glucide were isolated together with 16 known compounds. Their structures were clarified as 2-methoxy-2-(4'-hydroxyphenyl)ethanol, junipediol A 2-O-beta-D-glucopyranoside and L-fucitol, respectively. (C) 2002 Published by Elsevier Science Ltd.
