红花忍冬的黄酮类成分研究

Flavonoids from the Aerial Parts of Lonicera syringantha Maxim.

对红花忍冬(Lonicera syringanthaM axim.)干燥地上部分进行化学成分研究。分离鉴定了5个黄酮类化合物:木犀草素(Ⅰ)、木犀草素-7-O-β-D-葡萄糖苷(Ⅱ)、香叶木素(Ⅲ)、香叶木素-7-O-β-D-葡萄糖苷(Ⅳ)和柏黄酮(Ⅴ)。经文献检索,这5个化合物均为首次从该种植物中分离得到,其中化合物Ⅲ、Ⅳ、Ⅴ系首次从该属植物中分得。

Flavonoids from the aerial parts of Lonicera syringantha Maxim. were studied. Five flavonoids were isolated and their structures were identified as luteolin （Ⅰ）, luteolin--7-O-β-D-glucoside （Ⅱ）, diosmetin （Ⅲ）, diosmetin-7-O-β-D-glucoside （Ⅳ）, cupressuflavone （Ⅴ）, All these compounds were first isolated from this species, compounds Ⅲ, Ⅳ and Ⅴ were isolated from the genus Lonicera Linn. for the first time.
