Four lignans, blechnic acid (1), 7-epiblechnic acid (3), 8-epiblechnic acid (6) and brainic acid (2), were isolated from six Blechnaceous ferns, Blechnum orientale, Struthiopteris amabilis, S. niponica, Woodwardia orientalis, W. prolifera and Brainea insignis. Their structures were determined by spectroscopic methods and chemical conversion.
从六种鳞毛蕨类植物中分离出四种木脂素,即贝莱尼酸(1)、7-表贝莱尼酸(3)、8-表贝莱尼酸(6)和脑酸(2),这六种植物分别是东方鳞毛蕨、可爱鳞毛蕨、日本鳞毛蕨、东方木蕨、多叶木蕨和斑纹鳞毛蕨。通过光谱法和化学转化确定了它们的结构。
