从胡桃楸(Juglans mandshurica)茎皮中分离得到4个黄酮化合物、2个没食子糖,并评估了其抗补体活性。取胡桃楸茎皮(3.0kg)以甲醇室温提取24h,得到深褐色粗提物(390g)。取部分(300g)混悬于水(2 500mL),以己烷提取,得到己烷溶解部分(48g)。水层依次以二氯甲烷、乙酸乙酯、丁醇提取 Four flavonoid compounds and two gallose sugars were isolated from the bark of Juglans mandshurica and its anti-complement activity was evaluated. The walnut bark bark (3.0 kg) was extracted with methanol at room temperature for 24 h to obtain a dark brown crude extract (390 g). A portion (300 g) was suspended in water (2 500 mL) and extracted with hexane to give a hexane-dissolved portion (48 g). The aqueous layer was extracted with dichloromethane, ethyl acetate and butanol.
