摘要
从斜脉暗罗（Ｐｏｌｙａｌｔｈｉａ ｐｌａｇｉｏｎｅｕｒａ Ｄｉｅｌｓ）的种子中分离到化合物Ｐ４ 及Ｐ５，经ＩＲ、１Ｈ－ＮＭＲ、１３ Ｃ－ＮＭＲ及ＭＳ谱鉴定，Ｐ４ 为海南哥纳香甲素，Ｐ５ 为具有Ｃ５－ＯＨ 的单四氢呋喃环型番荔枝内酯，命名为斜脉暗罗素甲（ｐｌａｇｉｏｎｉｃｉｎ Ａ）。
Compounds P 4 and P 5 had been isolated from the seeds of Polyalthia plagioneura Diels.The former was identified as howiicin A by the spectral analysis of [α] D, IR, 1H NMR, 13 C NMR and MS, the latter was characterized as a new monotetrahydrofuran annonaceous acetogenin with C 5 OH, which was named plagionicin A.
