Abstract

Two major anthocyanins (A1 and A2) were isolated from peels of the spears of Asparagus officinalis cv. Purple Passion. They were purified by column, paper and high-performance liquid chromatographic separations, and their structures were elucidated by high-resolution Fourier transform ion cyclotron resonance mass spectrometry (HR-FT-ICR MS), 1H, 13C and two-dimensional NMR spectroscopic analyses and either acid or alkaline hydrolysis, respectively. A1 was identified as cyanidin 3-[3''-(O-beta-d-glucopyranosyl)-6''-(O-alpha-l-rhamnopyranosyl)-O-beta-d-glucopyranoside], whereas A2 was cyanidin 3-rutinoside, which is widely distributed in higher plants. Oxygen radical absorbance capacity (ORAC) assays proved their high antioxidant activities.

摘要

从紫芦笋品种“Purple Passion”的嫩茎外皮中分离出了两种主要的花青素（A1和A2）。通过柱色谱、纸色谱和高效液相色谱分离对它们进行了纯化，并分别通过高分辨率傅里叶变换离子回旋共振质谱（HR-FT-ICR MS）、1H、13C和二维核磁共振光谱分析以及酸或碱水解来阐明它们的结构。A1被鉴定为矢车菊素3-[3''-(O-β-D-吡喃葡萄糖基)-6''-(O-α-L-吡喃鼠李糖基)-O-β-D-吡喃葡萄糖苷]，而A2是矢车菊素3-芸香糖苷，它广泛分布于高等植物中。氧自由基吸收能力（ORAC）测定证明了它们具有高抗氧化活性。
