目的 黑龙江省富含鞣质成分的榛子叶的开发与应用。方法 利用 ¹ HNMR、¹³CNMR、FABMS、CD谱及¹ H- ¹ HCOSY二维谱与化学方法鉴定从榛子叶中分离得到的化合物的结构。结果 所得到的化合物分别为 :quercetin- 3- O-β- D - glucuronise;1,2,3,4,6 - penta- O- galloyl-β-D- glucose;1,2,3,6 - tetra-β- D- glucose;casuarictin;rugosin C;degalloylrugosin F;tellimagrandin 和 heterophylliin A。结论 首次从榛子叶中分离得到 8种鞣质化合物

Object To study the tannin componen ts in the leaf of Corylus heterophylla Fisch. ex Bess. Methods The tannin components were extracted with solvents and separa ted on Toyopearl HW-40 (F) and Sephadex LH-20 columns. They were identified by ¹HNMR, ¹³CNMR, FABMS, CD and 2-dimensional ¹H- 1HCOSY spectra and chemical methods. Results 8 compounds were obtained for the first time from the plant. They were quercetin-3-O-β-D-glucuronide (Ⅰ); casuarictin (Ⅱ); rugosin C (Ⅲ); 1, 2, 3, 4, 6-penta-O-galloyl-β-D-glucose (Ⅳ), 1,2, 3, 6-tetra-O-galloyl-β-D-glucose (Ⅴ), degalloylrugosin F (Ⅵ); tellimagrandin Ⅱ (Ⅶ) and heterophyllin A (Ⅷ). Conclusion Compound Ⅷ, heterophyllin A was new.
