Two new polyphenols, 4,6-di-O-galloylarbutin and 2,4,6-tri-O-galloyl-D-glucose, were isolated from the root of Bergenia purpurascens, which also contains 6-O-galloylarbutin, bergenin and its gallates, and five other phenolic compounds. The structures of the new compounds were determined by chemical and spectroscopic methods.
两种新的多酚,4,6-二-O-galloylarbutin 和 2,4,6-tri-O-galloylarbutin 和 2,4,6-tri-O-galloylarbutin 和 2,4,6-tri-O-galloylarbutin 和它的没食子酸酯和其他五种酚类化合物。新化合物的结构是通过化学和光谱方法确定的。
