     从黑果腺肋花楸(Aronia melanocarpa Elliot)幼苗和果实的乙醇提取物中,经过硅胶柱色谱、凝胶柱色谱、聚酰胺柱色谱、制备薄层色谱以及RP-HPLC等多种色谱手段共分离得到31个化合物,利用理化常数测定、光谱数据分析和化学方法鉴定了其中28个化合物的结构,分别属于三萜类、黄酮类、酚酸类、甾醇类、糖及糖苷类等成分,它们分别为16-O-乙酰基-21-O-当归酰基茶苷元A 3-O-[β-D-吡喃半乳糖基(1→2)][β-D-吡喃木糖基(1→2)-α-L-吡喃阿拉伯糖基(1→3)]-β-D-吡喃葡萄糖醛酸(16-O-acetyl-21-O-angeloyltheasapogenol A 3-O-[β-D-galactopyranosyl(1→2)][β-D-xylopyranosyl(1→2)-α-L-arabinopyranosyl(1→3)]-β-D-glucopyranosiduronic

1. Aronia melanocarpa Elliot, belonging to Rosaceae, is a low wood origin of the northeast of America. It was introduced and cultivated in China from the 1990's. The fruits and the extracts of Aronia melanocarpa have been reported to have antioxidant, anti-inflammatory, anticancer and antihyperglycemic activities, and also have the therapeutic effects on cardiovascular diseases.
    From the ethanol extracts of the seedlings and the fruits of Aronia melanocarpa Elliot, 31 compounds were isolated by various chromatographic and recrystallized methods. On the basis of analysis of NMR, MS data, measurement of physico-chemical characters and chemical methods, the structures of 28 compounds, which belonging to triterpenes, flavonoids and so on, were identified as: 16-O-acetyl-21-O-angeloyl theasapogenol A 3-O-[β-D-galactopyranosyl (1→2][β-D-xylopyranosyl(1→>2)-α-L-arabinopyranosyl(1→)3)]-β-D-glucopyranosiduronic acid (1), 16,28-O-diacetyl-21-O tigloyltheasapogenol A 3-O-[β-D-galactopyranosyl(1→2)][β-D-xylopyranosyl(1→2) -α -L-arabinopyranosyl(1→3)]-β-D-glucopyranosiduronic acid (2), friedelin (3), betulinic acid (4), betulin (5), 23-hydroxybetulinic acid (6), betulinic acid 3β-caffeate (7), 23-hydroxybetulinic acid 3β-caffeate (8), ursolic acid (9), 2α-hydroxyoleanolic acid (10), 3β-O-acetylursolic acid (11), 19α-hydroxyursolic acid (12), 2α,3α-dihydroxyursolic acid (13), 2α, 3α,19α-trihydroxyursolic acid (14), (-)-epicatechin(15),
