摘要
目的：建立荷叶中槲皮素和荷叶碱的含量分析方法，考察不同品种、产地以及采收时间对于荷叶中槲皮素及荷叶碱的含量的影响。方法：采用高效液相色谱（HPLC）法测定湖北境内3个品种和5个不同产地和不同采收时间的荷叶中荷叶碱、槲皮素两类有效成分的含量。结果：荷叶碱和槲皮素含量分别在1．78～28．56，5．35～53.52mg·L^-1范围内呈良好的线性关系。由于品种、产地、采收时间不同，荷叶中荷叶碱和槲皮素的含量相差较大。其中汉川、潜江、武汉汉阳近郊荷叶的指标成分含量较高，九月为荷叶采收的最佳时期。结论：本方法可筛选荷叶优良药用品种并指导其合理采收。
OBJECTIVE To establish a method for quantitative analysis of quercetin and nuciferine. To inspect the influence factors on the content of nuciferine and quercetin of Folium Nelumbinis of different .species, produced in different places and collected in different months. METHODS The content of nuciferine and quercetin in Folium Nelumbinis samples of 3 species from 5 different areas in different months of Hubei province was determinated by HPLC method. RESULTS There were excellent linear correlation over the range of 1.78 - 28. 56 mg·L^-1 and 5. 35 - 53. 52 mg·L^-1 for nuciferine and quercetin respectively. The contents of active components in Folium Nelumbinis samples are rather different on the basis of the species, places and months for collecting. The areas of Hanchuan, Qianjiang and Hanyang were relatively higher than that from other habitats and the month of september is the best collection time. CONCLUSION This method is feasible to screen the fine spices and to guide the harvest of Folium Nelumbinis.
