目的研究金毛狗脊Cibotium barometz的化学成分。方法采用柱色谱和高效液相色谱法分离纯化金毛狗脊中的化学成分,并采用光谱法鉴定其结构。结果从金毛狗脊中分离得到的6个化合物分别鉴定为6-0.原儿茶酰基-D-葡萄糖(1)、3-O-咖啡酰基-D-葡萄糖(2)、1-O-咖啡酰基-β-D-葡萄糖(3)、咖啡酸(4)、原儿茶酸(5)、对羟基苯甲酸(6)。结论其中化合物1~3、6均为首次从金毛狗脊中分离得到,化合物1为新的酚苷,命名为金毛狗脊苷D。
Objective To study the chemical constituents from Cibotium barometz continuously. Methods Column chromatography and HPLC were carried out to isolate and purify the chemical compounds in the ethanol extract from C. barometz, and their structures were elucidated on the basis of spectroscopy. Results Six compounds isolated from C. barometz were identified as 6-O-protocatechuoyl-D-glucopyranose (1), 3-O-caffeoyl-D-glucopyranose (2), 1-O-caffeoyl-β-D-glucopyranose (3), caffeic acid (4), protocatechuic acid (5), and p-hydroxybenzoic acid (6). Conclusion Compounds 1-3 and 6 are isolated from C. barometz for the first time, and compound 1 is a novel penolic glucoside named cibotiumbaroside D.
