Amide compounds are the major bioactive substances in black pepper. Black pepper extracts were fractionated by high-speed countercurrent chromatography resulting in three compounds: dehydropipernonaline, piperine and (2E,4E,12Z)-N-isobutyl-octadecatrienamide, and four fractions which were separated by preparative HPLC to yield ten purified compounds: retrofractamide-A, (2E,4E)-N-isobutyl-decadienamide, retrofractamide-C, piperoleine A, dehydropiperoleine A, retrofractamide-B, piperoleine B, pipernonaline, pipercyclobutanamides A and (2E,4E,14Z)-N-isobutyleicosa-2,4,14-trienamide as identified by ESI-MS and NMR analysis. The results of the present study indicated that HSCCC is an effective technique for the preparation of bioactive amide compounds from black pepper. (C) 2012 Elsevier B.V. All rights reserved.
