【摘要】 目的测定甘肃不同产地淫羊藿中淫羊藿苷及总黄酮含量及土壤养分对其影响。方法采用高效液相色谱法和紫外分光光度法分别测定淫羊藿苷和总黄酮的含量,并与产地土壤养分进行相关性分析。结果以宕昌县淫羊藿苷、总黄酮含量最高,分别为1.16%、9.44%;崆峒山淫羊藿苷、总黄酮含量较低,分别为0.90%、6.49%。淫羊藿苷、总黄酮含量与土壤有机质含量呈显著正相关关系。结论甘肃产地淫羊藿质量较好,含量皆高于药典规定,人工栽培增施有机肥可提高有效成分含量。更多还原

【Abstract】 Objective To determine the content of icariin and flavonids in Epimedium brevicornum Maxi of different place in Gansu Province and interrelationships of active component and soil nutrients. Methods Icariin was used as the chemical reference substance to establish HPLC and ultraviolet spectrophotometry methods for content determination of icariin and total flavonoids. Results The content of icariin and total flavonids in Tanchang city gansu province was the highest,it was 1. 16% and 9. 44%. Kongtong Mountain was the lowest in Gansu. The content of icariin and flavonids had positive correlations with soil organic matter. Conclusion The content of icariin and flavonids in Epimedium brevicornum Maxi was better than its content of Pharmacopoeia of the PRC,increase organic fertilizer can improve the effective composition content.更多还原
