摘要： A simple, inexpensive, and efficient method for separation and purification of the α-and β-forms of penta-O-galloyl-D-glucose (PGG) without the need for HPLC. The methods provided herein are useful for separation α-PGG or β-PGG from a mixture containing α-PGG and β-PGG and other chemicals. The method for separation of α-PGG from a mixture of α-PGG and β-PGG comprises the steps of: adding water to a sample containing 50% or more α-PGG and 50% or less β-PGG; mixing the PGG and water to dissolve the PGG; filtering out any undissolved particles; and allowing the filtered solution to stand undisturbed until crystals form.

摘要： A method to synthesize benzyl group protected alpha-pentagalloylglucose (α-PGG) and related compounds. The method comprises the steps of: suspending a highly reactive acylation agent and an acylating catalyst in a donor solvent; adding α-D-glucose or an analogue thereof to the mixture; reacting the mixture at room temperature for a time sufficient for reaction to occur; evaporating the solvent; taking up the residue in an appropriate solvent; filtering the residue and solvent mixture; and evaporating off the solvent.
摘要翻译：合成苄基保护的α-五加酰葡萄糖（α-PGG）和相关化合物的方法。该方法包括以下步骤：将高反应性酰化剂和酰化催化剂悬浮于供体溶剂中; 向混合物中加入α-D-葡萄糖或其类似物; 使混合物在室温下反应一段足以使反应发生的时间; 蒸发溶剂; 在适当的溶剂中吸收残留物; 过滤残留物和溶剂混合物; 并蒸发掉溶剂。
