从榛子叶提取物中分离出两种新的鞣花单宁单体，太子草素 A (12) 和 E (13)，以及三个二聚体，太子草素 B (17)、C (18) 和 D (19)，并根据光谱和化学证据阐明了它们的结构。还分离了七种已知单宁：1,2,3,6-四-O-没食子酰-β-D-葡萄糖、tellimagrandin II、casuarictin、casuarinin、rugosin C、rugosin F 和 degalloylrugosin F。
Two new ellagitannin monomers, heterophylliins A (12) and E (13), and three dimers, heterophylliins B (17), C (18) and D (19), were isolated from leaf extract of Corylus heterophylla (Betulaceae), and their structures were elucidated based on spectral and chemical evidence. Seven known tannins, 1, 2, 3, 6-tetra-O-galloyl-β-D-glucose, tellimagrandin II, casuarictin, casuarinin, rugosin C, rugosin F, and degalloylrugosin F, were also isolated.
