Abstract

Phytochemical reinvestigation on the whole plants of Benth. afforded two new diprenylated flavanones, derriflavanones B and C (-), together with thirty-two known compounds, including sixteen flavonoids (-), eleven aromatic compounds (-), and five chlorophylls (-). All known compounds were first isolated from this plant. The structures of these compounds were determined by analysis of the NMR spectroscopy, mass data, IR spectra, UV spectra, optical rotation and by comparison with literature data.

摘要

对 Benth. 全植物的植物化学再研究提供了两种新的二萜化二氢黄酮，即 derriflavanones B 和 C(-)，以及三十二种已知化合物，包括十六种类黄酮(-)、十一种芳香族化合物(-)和五种叶绿素(-)。所有已知化合物均首次从该植物中分离得到。这些化合物的结构通过分析 NMR 光谱、质谱数据、IR 光谱、UV 光谱、旋光度以及与文献数据的比较来确定。
