香鳞毛蕨中的两个新化合物

Two New Compounds from Dryopteris fragrans

目的:对香鳞毛蕨Dryopteris fragrans(L.)Schott的化学成分进行研究。方法:通过硅胶、ODS、Sephadex LH-20等柱色谱和HPLC等技术分离纯化香鳞毛蕨中的化学成分,并采用现代波谱法鉴定其结构。结果:从香鳞毛蕨水提取物大孔吸附树脂30%乙醇洗脱组分分离纯化了两个新的化合物,分别鉴定为:trans-S-trans-p-hydroxy cinamic acid-9-β-D-xylpyranosyl(1→2)-β-D-glucopyranosyl ester(1)和methyl-2-ethyl-6-((3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)benzoate(2)。结论:化合物1和2为新化合物,分别命名为香鳞毛蕨苷J(1)和香鳞毛蕨苷K(2)。

Objective： To study the chemical constituents of Dryopteris fragrans.Methods： Two new compounds were isolated and purified from this plant by column chromatography and their structures were elucidated through spectroscopic analysis.Results： Two new compounds were identified as trans-S-trans-p-hydroxy cinamic acid-9-β-D-xylpyranosyl（ 1→2）-β-D-glucopyranosyl ester,methyl-2-ethyl-6-（（ 3,4,5-trihydroxy-6-（ hydroxymethyl） tetrahydro-2H-pyran-2-yl） oxy） benzoate.Conclusion： Compounds 1 and 2 are new and named fragranoside J and fragranoside K.
