ABSTRACT:
Described are mixtures of at least four of the alkadienamides defined according to the structure:wherein R represents C1-C2n-alkyl; R1is 2-methyl-1-propyl and R2is hydrogen, or R1and R2taken together is a moiety having the formula —(CH2)n— wherein n is 4 or 5, or compositions containing substantial concentrations of such mixtures, prepared according to novel processes: (a) extraction of a ground substantially dried fruit of one of thePiperspecies,Piper longumLinn orPiper peepuloides; (b) natural product-forming synthesis; or (c) synthetic product-forming synthesis. Also described are uses of the thus-formed products for augmenting, enhancing or imparting an aroma, taste, chemesthetic effect and/or antibacterial effect in or to a consumable material and/or in the oral cavity and/or on the mammalian epidermis.
