Alkaloids and lignans from the stems of Piper betel were studied. Compounds were isolated and purified by repeated silica gel, reverse phase silica gel, Sephadex LH-20 column chromatog., and preparative thin layer chromatog. The structures were elucidated on the basis of spectral anal. From the Et acetate soluble fractions of the 70% acetone extract, 10 compounds were isolated and identified as piperine; pellitorine; N-isobutyl-2E,4E-dodecadienamide; dehydropipernonaline; piperdardine; piperolein-B; guineensine; (2E,4E)-N-isobutyl-7-(3′,4′-methylene dioxyphenyl)-2,4-heptadienamide; syringaresinol-O-β-D-glucopyranoside; and pinoresinol (10). All compounds were isolated from the plant for the first time, and syringaresinol-O-β-
(2E,4E)-N-Isobutyldeca-2,4-dienamide (cas: 18836-52-7) belongs to amides. Amides can be viewed as a derivative of a carboxylic acid RC(=O)OH with the hydroxyl group –OH replaced by an amine group −NR′R″; or, equivalently, an acyl (alkanoyl) group RC(=O)− joined to an amine group. Ionic, or saltlike, amides are strongly alkaline compounds ordinarily made by treating ammonia, an amine, or a covalent amide with a reactive metal such as sodium.HPLC of Formula: 18836-52-7
