Three pyrrole alkaloids were isolated from Bolbostemma paniculatum. Their structures were elucidated as 4-(2-formyl-5-methoxymethylpyrrol-1-yl)butyric acid methyl ester (1), 2-(2-formyl-5-methoxymethylpyrrol-1-yl)-3-phenylpropionic acid methyl ester (2) and alpha-methyl pyrrole ketone (3) by spectroscopic techniques. Among them, 1 and 2 are new compounds.

Three 2-substituted pyrroles (2-acetylpyrrole, pyrrole-2-carboxaldehyde and pyrrole-2-carboxylic acid), which are products of the Maillard browning reaction, were reacted with nitrite in buffer solution (pH 3) at 50 degrees C for 24 hr. The reaction mixtures were extracted with methylene chloride
Aroma extract dilution analysis (AEDA) is widely used for the screening of aroma-active compounds in gas chromatography-olfactometry (GC-O). In this study, three aroma dilution methods, (I) using different test sample volumes, (II) diluting samples, and (III) adjusting the GC injector
