北野菊黄酮类成分研究

STUDIES ON THE FLAVONOIDS FROM DENDRANTHEMA LAVANDULIFOLIUM

摘要: 从北野菊(Dendranthema lavandulifolium)全草中分得四个黄酮类化合物。经光谱(UV,IR,氢谱,碳谱,质谱等)方法鉴定其结构,分别为木樨草素(I),洋芹素(I),金合欢素-7-O-α-L-鼠李糖基(1→6)-β-D-葡萄糖甙(II)和金合欢素-7-O-α-L-鼠李糖基(1→6)-2-O-乙酰基-β-D-葡萄糖基(1→2)-β-D-葡萄糖甙(IV)。其中,I和I为首次从该植物中得到,IV为一个新化合物。

Abstract: From the whole plant of Dendranthema lavandulifolium , two flavonoides (I, II) and two flavone glycosides (III, IV) were isolated. They were identified as luteolin (I), apigenin (II), 5-hydroxy-4′-methoxy flavone-7-O-α-L-rhamnopyranosyl(1→6)-β-D-glucopyranosyl (acaciin III) and 5-hydroxy-4′-methoxy flavone-7-O-α-L-rhamnopyranosy1(1→6)2-O-acety1-β-D-glucopyranosyl(1→2)-β-D-glucopyranoside (IV) by means of IR, UV, ¹H-NMR,¹³C-NMR, EI-MS, HRFAB, etc. Among these four compounds, I, II were isolated for the first time from this plant, IV is a new compound.
