Two new caffeoyl quinic acid α-glucosides, together with three known caffeoyl quinic acids and five known flavonoid glucosides, were isolated from the leaves of Moringa oleifera Lam. The structures of the new compounds were elucidated as 4-O-(4'-O-α-D-glucopyranosyl)-caffeoyl quinic acid (1) and 4-O-(3'-O-α-D-glucopyranosyl)-caffeoyl quinic acid (2) by spectroscopic analyses.
从辣木（Moringa oleifera Lam.）叶中分离得到两种新的咖啡酰奎宁酸α-葡萄糖苷，以及三种已知的咖啡酰奎宁酸和五种已知的黄酮苷。通过光谱分析，鉴定了这两种新化合物的结构分别为 4-O-(4'-O-α-D-吡喃葡萄糖基）-咖啡酰奎宁酸（1）和 4-O-(3'-O-α-D-吡喃葡萄糖基）-咖啡酰奎宁酸（2）。
