Three new amides, pipgulzarine (1), pipzorine (2), and piptahsine (3), have been isolated from the dried seeds of Piper nigrum Linn. along with nine known constituents: (2E,4E,8Z)-N-(isobutyl)eicosatrienamide, pellitorine, pipercide, piperine, stigmastanol, stigmasterol, decurrenal, stigmasterol 3-O-β-D-glucopyranoside, and 5,10(15)-cadinen-4-ol. The structures of the new constituents have been established
从Piper nigrum Linn的干燥种子中分离出了三种新的酰胺,pipgulzarine(1),pipzorine(2)和piptahsine(3)。以及九种已知成分:(2 E,4 E,8 Z)-N-(异丁基)二十碳三烯酰胺,pellitorine,pipercide,piperine,stigmastanol,Stigmasterol,后肾上腺素,Stigmasterol 3 - O - β -D-D-吡喃葡萄糖苷和5, 10(15)-cadinen-4-ol。新成分的结构已确定为(2 E ,11 E )-12-(苯并[1,3]二恶酚-5-基) -N- (2-甲基丙基)dodeca-2,11-二烯酰胺(1),(2 E ,12 Z ) -N- (4-甲基戊基)十八烷基-2,12-二烯酰胺(2)和(2 E ,4 S )-4-羟基-N- (2-甲基丙基)己-2-烯酰胺(3)。的结构1 -
