Twenty-three compounds, a novel neolignan nine known neolignans and 13 known alkaloids, were isolated from a methanol extract of stems of Piper argyrophylum. The structure of the new neolignan, 4-(2-piperonyl-2-hydroxy-1-methylethyl-2,5-dimethoxy-2-(2-propenyl)-3,5-cyclohexadien-1-one, was elucidated on the basis of its spectral data, whereas the known neolignans and alkaloids were identified by comparsion
二十三种化合物,一种新型的新木脂素,九种已知的新木脂素和 13 种已知的生物碱,是从 Piper argyrophylum 茎的甲醇提取物中分离出来的。新木脂素 4-(2-piperonyl-2-羟基-1-甲基乙基-2,5-二甲氧基-2-(2-丙烯基)-3,5-环己二烯-1-one)的结构在其光谱数据为基础,而已知的新木脂素和生物碱是通过将它们的光谱数据与先前报道的光谱数据进行比较来鉴定的。所有化合物都是来自 P. argyrophylum 的新化合物。
