摘要
为防止品种混杂,筛选药用或茶用菊花的专用品种,以不同产地来源的8个药用菊花品种16个样品为试材,采用超高效液相色谱法和比色法测定不同产地药用菊花的品质成分含量;并基于主成分分析和聚类分析,对不同产地药用菊花品种产量与品质进行综合评价。结果表明,不同产地药用菊花品种单株花头数变异系数(39.03%)最大,是构成药用菊花单株花头干重的主要因素(r=0.800),以枣庄红心菊单株花头数(496.50)最多、单株花头干重最高;绿原酸、3,5-O-二咖啡酰基奎宁酸和总黄酮等药效成分在不同来源的样本中差异显著(P<0.05),上述三种成分在滁州产滁菊中相对含量较高,分别为3.75%、8.07%、16.08%,这与其品质成分综合评价结果一致,说明滁州滁菊药效较优。13个性状指标的主成分分析提取出药效因子、高产因子、总黄酮因子和花径因子4个主成分,其累计贡献率为84.34%;综合评价得分排在前3位的依次为枣庄引种的红心菊、早小洋菊、滁菊。结合聚类分析结果,判定在原产地,滁州滁菊适于药用;在枣庄引种地,红心菊为优选的高产品种,早小洋菊为综合品质优良的品种。通过建立药用菊花品种产量和品质的综合评价体系,可为我国药茶两用菊花新品种的引种筛选和药食同源利用提供理论依据。
In order to prevent the mixing of varieties and screen special medicinal or tea Chrysanthemum morifolium varieties,16 samples of 8 medicinal C.morifolium varieties from different producing areas were used in this study.Ultrahigh performance liquid chromatography and colorimetry were used to determine the quality components from different producing areas,we also determined their yield and quality based on principal component analysis(PCA)and cluster analysis(CA).The results showed that the variation coefficient of the amount of single capitulum per plant was the largest(39.03%)among the yield indexes,which was the main factor that constituted the dry weight of single capitulum per plant r=0.800).Furthermore,the‘Hongxin Ju’from Zaozhuang had the highest value in both the amount of single capitulum(496.50)and dry weight of single capitulum per plant.The contents of medical components,including chlorogenic acid,3,5-O-dicaffeoylquinic acid and total flavonoids showed significant differences(P<0.05)among different samples from various areas,and the three compounds in‘Chuju’from Chuzhou had relative higher levels(3.75%,8.07%and 16.08%,respectively),which was consistent with the comprehensive evaluation results of its quality components,and indicating that‘Chuju’from Chuzhou was suitable for medicinal use.Four principal components were extracted from the PCA of 13 traits indexes,including pharmacodynamic factor,high yield factor,total flavonoid factor and flower diameter factor,and their cumulative contribution rate reached 84.34%.The comprehensive scores of‘Hongxin Ju’,‘Zaoxiaoyang Ju’and‘Chuju’after introduced to Zaozhuang ranked the top three among 16 samples of 8 varieties from various areas.Combined with the results of CA,it indicated that in the original area,'Chuju'from Chuzhou was more suitable for medical use,in the introducing area of Zaozhuang,‘Hongxin Ju’was a high-yielding variety,and‘Zaoxiaoyang Ju’was a variety with good comprehensive quality.In summary,a comprehensive evaluation system for the yield and quality of medicinal C.morifolium varieties was established to provide a theoretical basis for the introduction and screening of new varieties of medicinal and tea C.morifolium and the homologous utilization of medicine and food in China.
