A metabolite of Piperine | [Definition]
ChEBI: A monocarboxylic acid that is (E)-penta-2,4-dienoic acid substituted by a 1,3-benzodioxol-5-yl group at position 5. It has been isolated from black pepper (Piper nigrum). | [Purification Methods]
Crystallise the acid from EtOH. It turns yellow in light. It sublimes with partial decomposition. It has UV max 340nm (MeOH). [Beilstein 19 H 281, 19 II 30, 19 III/IV 3565.] |
