Abstract

A Xiphidium caeruleum flower extract was separated by semi-preparative HPLC into five fractions, from which three flavonoids, two phenylphenalenones and 17 phenylphenalenone-related compounds including five unknown compounds, were isolated and their structures elucidated by Liquid Chromatography-Diode Array Detection-Solid Phase Extraction-Nuclear Magnetic Resonance spectroscopy (LC-DAD-SPE-NMR) and mass spectrometry (MS). This is the first report of the co-occurrence of phenylphenalenones and flavonoids in the Haemodoraceae family. The ecological implications of flavonoids and various phenylphenalenone-type compounds and their putative biosynthesis sites in X. caeruleum are subject to discussion.

摘要

从蓝星花中分离出一个半制备高效液相色谱法，将其分为五个部分，从中分离出三种黄酮类化合物，两种二苯并菲酮和 17 种二苯并菲酮相关化合物，包括五种未知化合物，通过液相色谱-二极管阵列检测-固相萃取-核磁共振波谱（LC-DAD-SPE-NMR）和质谱（MS）鉴定其结构。这是 Haemodoraceae 科中同时存在二苯并菲酮和黄酮类化合物的首次报道。本文讨论了蓝星花中黄酮类化合物和各种二苯并菲酮型化合物及其可能的生物合成部位的生态意义。
