自紫草科植物东北鹤虱Lappula echinata Gilib.果实中分离出十六种化合物。其中晶ⅩⅢ(—)—绿花倒提壶酸((—)-viridifloric acid)为一新的天然产物,晶ⅩⅥ为一新酯甙,对香豆酰-α-L-鼠李吡喃糖甙[1-(p-coumaroyl)-α-L-rhamnopyranose]。并鉴定其它八种化合物为棕榈酸Ⅰ、尿囊素Ⅲ、腺嘌呤Ⅳ、腺甙Ⅶ、L-亮氨酸Ⅹ、L-缬氨酸Ⅺ、L-酪氨酸Ⅻ和琥珀酸ⅩⅤ。Ⅰ、Ⅵ、ⅩⅢ、ⅩⅤ和ⅩⅥ显示了不同程度的抗菌活性。 Sixteen compounds were isolated from the fruit of the comfrey plant, Northeastern Happo Lappula echinata Gilib. Among them, crystal XIII(-)-green acid ((-)-viridifloric acid) is a new natural product. Crystal XVI is a new ester, p-coumaroyl-α-L-rhamopyranose.甙 [1-(p-coumaroyl)-α-L-rhamnopyranose]. And the other eight compounds were identified as palmitic acid I, allantoin III, adenine IV, adenine VII, L-leucine X, L-proline XI, L-tyrosine XII and succinate XV. I, VI, XIII, XV and XVI show different degrees of antibacterial activity.
