  2-O-β-d-Glucopyranosyl-carboxyatractyligenin from Coffea L. inhibits adenine nucleotide translocase in isolated mitochondria but is quantitatively degraded during coffee roasting

  摘要：

  Atractyloside (1) and carboxyatractyloside (2) are well-known inhibitors of the adenine nucleotide translocase (ANT) in mitochondria, thus effectively blocking oxidative phosphorylation. Structurally related derivatives atractyligenin (3), 2-O-beta-D-glucopyranosyl-atractyligenin (4), 3'-O-beta-D-glucopyranosyl-2'-O-isovaleryl-2 beta-(2-desoxy-atractyligenin)-beta-D-glucopyranoside (5), and 2-O-beta-D-glucopyranosyl-carboxyatractyligenin (6) were isolated from raw beans of Coffea L and the impact of 1-6 on ANT activity was evaluated in isolated mitochondria. Among the coffee components, 6 significantly inhibited ANT activity leading to reduced respiration. Quantitative analysis in commercial coffees, experimental roastings of coffee, and model experiments using purified compound 6 consistently revealed a complete degradation during thermal treatment. In comparison, raw coffee extracts were found to contain high levels of 6, which are therefore expected to be present in food products enriched with raw coffee extracts. This implies the necessity of analytically controlling the levels of 6 in raw coffee extracts when used as additives for food products. (C) 2013 Elsevier Ltd. All rights reserved.

  Eight previously undescribed acyl atractyligenin and carboxyatractyligenin glycosides were isolated from whole Antennaria rosea subsp. confinis (Greene) R. J. Bayer (Compositae) [syn. Leontopodium leontopodioides (Willd.) Beauv. (Asteraceae)] plants and their structures were determined by spectroscopic and chemical methods. The compounds were trivially named leontopodiosides F-M. Seven of the compounds

  从整个 Antennaria rosea subsp. 中分离出八种以前未描述的酰基苍术苷元和羧基苍术苷元。confinis (Greene) RJ Bayer (Compositae) [syn. Leontopodium leontopodioides (Willd.) Beauv。(菊科)]植物及其结构通过光谱和化学方法确定。这些化合物被简单地命名为leontopodiosides FM。其中七种化合物显示出对胰脂肪酶的有效体外抑制活性，IC50 值范围为 3.4 至 52.5 μM，表明它们参与了先前观察到的这种植物在减少大鼠甘油三酯吸收方面的作用。
