西红花主要活性成分含量变异规律

目的： 提示西红花中主要活性成分的变异规律。 方法： 采用高效液相色谱法测定西红花苷含量，并分析了产地、施肥方式、采收时间、遮覆方式、叶形态特征、产量性状与西红花苷含量的关系。 结果： 不同产地种源、施肥方式、遮覆方式的西红花中西红花苷含量存在显著差异（P<0.05），西红花苷含量与柱头重、种球重、叶片数、叶长呈负相关性，与采收时间没有显著的关系。 结论： 西红花主要活性成分含量存在一定的变异规律，覆草不遮阴、配合施用有机肥与无机肥有利于西红花苷含量积累，针对产量筛选优良品系时，应优先考虑在叶较长、叶片少的品系中选择，本文的研究为西红花优质栽培与优良品系筛选提供了依据。

Variation of Main Active Ingredient Contents in Crocus sativus

Objective: To study the variation of the main active ingredient contents in Crocus sativus. Method: The crocin contents in C. sativus were determined by high performance liquid chromatography (HPLC), after which the relationships between contents and origins, fertilization mode, picking time, covering methods, morphological character of leaves, yield character were studied. Result: It showed that there was an obviously difference between contents in C. sativus from different origins, fertilization mode and covering methods. Besides, there was a negative correlation between contents and weight of stigma and seed, number and length of leaves. The picking time had no obvious correlation with contents. Thus it was founf that covering grass with no shade and cooperation application of organic and inorganic fertilizer could improve the crocin contents. Thus, to select high yield line in C. sativus, priority should be given to the line with longer and less leaves. Conclusion: The study has laid a foundation for high quality cultivation and superior line selection in C. sativus.
