From the CHCl(3)-soluble portion of the 70% EtOH extract of the stems and leaves of Dioscorea nipponica Makino, two new phenanthrenes, 7-hydroxy-2,3,5-trimethoxy-9,10-dihydrophenanthrene (1) and 2,2',7,7'-tetrahydroxy-4,4',6,6'-tetramethoxy-1,1'-biphenanthrenes (2), as well as three known phenanthrenes, 6-methoxycoelonin (3), 4,7-dihydroxy-2,3,6-trimethoxyphenanthrene (4), and 3,7-dihydroxy-2,4,6-trimethoxyphenanthrene (5), were isolated. The structures were determined by means of HR-MS, (1)H NMR, (13)C NMR, and HMBC experiments.
从薯蓣科植物穿龙薯蓣茎和叶的70%乙醇提取物的三氯甲烷可溶部分中,分离得到两个新的菲类化合物,7-羟基-2,3,5-三甲氧基-9,10-二氢菲(1)和2,2',7,7'-四羟基-4,4',6,6'-四甲氧基-1,1'-联菲(2),以及三个已知的菲类化合物,6-甲氧基异紫堇定(3)、4,7-二羟基-2,3,6-三甲氧基菲(4)和3,7-二羟基-2,4,6-三甲氧基菲(5)。通过高分辨质谱、氢核磁共振、碳核磁共振和异核多键相关实验确定了其结构。
