黄连木(Pistacia chinensis)为漆树科植物,产于中国南部,日本花园中亦有栽培。近年来有报道从叶中分离出酚类化合物和萜类,本文首次报道了黄连木中两种新的二聚4-芳基-香豆素(新黄酮)及二者的雌激素样活性。 将黄连木(采集于东京多摩森林科学林地花园和森林产品研究所)的新鲜嫩枝(约800g)切成小段,甲醇60℃提取2h,过滤,提取物真空浓缩至干,残渣在水和乙酸乙酯 Pistacia chinensis is a plant of the lacquer family and is produced in southern China. It is also cultivated in Japanese gardens. In recent years, it has been reported that phenolic compounds and terpenoids are isolated from leaves. For the first time, two new dimeric 4-aryl-coumarins (neoflavonoids) and their estrogenic activities have been reported in Pistacia chinensis. Fresh shoots (about 800 g) of Pistacia chinensis (collected in Tokyo Tama Forest Forest Garden and Forest Products Research Institute) were cut into small pieces, extracted with methanol at 60°C for 2 hours, filtered, and the extract was concentrated in vacuo to dryness. The residue was in water and acetic acid. Ethyl ester
