  摘要：

  对石榴（Punica granatum L.）树皮的化学分析导致分离出五种新的椰子单宁，分别是punicacorteins A、B、C和D，以及punigluconin，同时还发现了已知的椰子单宁，casuariin（6）和casuarinin（7）。基于化学和光谱证据，确定了punicacorteins A、B、C和D的结构为新型C-糖苷类型的椰子单宁，其中前两种具有独特的四苯基（gallagyl）酯基团（1和2），而后两种则在其位置替换为没食子酰基（3和4）。同时，punigluconin被表征为2, 3-二-O-没食子酰-4, 6-(S)-六羟基二苯酰葡萄糖酸（5）。

  Improved methods to prepare aqueous extracts of gallic acid esters including 1-O-galloyl-β- D -glucose (β-glucogallin) and other mucic acid gallates from the fruits of Emblica officinalis, wherein enrichment of gallic acid esters is achieved by Supercritical Fluid Extraction (SCFE) procedure, are disclosed. The use of such standardized extracts of gallic acid esters (greater than 40% w/w of gallic acid esters) in the manufacture of medicaments with diverse health benefits, is also disclosed.

  本文揭示了改进的方法，用于制备源自灰背鸮果实的没食子酸酯水提物，包括1-O-没食子酸-β-D-葡萄糖（β-葡萄糖酰没食子酸）和其他黏液酸没食子酸酯。其中，通过超临界流体萃取（SCFE）过程实现了没食子酸酯的富集。本文还揭示了使用这种标准化的没食子酸酯提取物（含有大于40％w / w的没食子酸酯）制造具有多种健康益处的药物的方法。
