目前的研究主要集中在市售板栗单宁提取物的成分上，以期为板栗单宁提取物的反应、构效关系和应用研究提供定量依据。使用 Sephadex LH-20 和纤维素色谱法分离出两种栗子单宁，即 vescalagin 和 Castalagin。这些化合物的结构已通过核磁共振和快原子轰击质谱法确定。一些其他成分已经被发现并通过色谱和光谱分析，但它们的结构尚未完全确定。这些结构特征与每种成分的定量结果一起，可以更好地了解复杂的商业栗子单宁提取物的作用模式。
Current research has focused on the composition of commercially used chestnut tannin extracts so as to provide a quantitative basis for studies of reactions, structure-property relationships, and applications of chestnut tannin extract. Two chestnut tannins, vescalagin and castalagin, have been isolated using chromatography on Sephadex LH-20 and cellulose. The structures of these compounds have been established by means of nuclear magnetic resonance and fast atom bombardment mass spectroscopy. Some other components have been found and analyzed by chromatography and spectroscopy, but their structures have not as yet been completely defined. These structural features, together with quantitative results for each component, provide a better understanding of the mode of action of complex commercial chestnut tannin extracts.
