目的 阐明华重楼主要药用成分的地理变异规律，为华重楼种质资源利用和原料林基地选址提供科学依据。 方法 以我国8省份10个种源华重楼为材料，对其根茎总酚酸、总黄酮、重楼皂苷Ⅰ、Ⅱ、Ⅵ和Ⅶ含量进行了测定、分析。 结果 不同地理种源间华重楼根茎总酚酸、总黄酮、重楼Ⅰ、Ⅱ、Ⅵ和Ⅶ含量差异均达极显著水平。不同种源华重楼根茎中总酚酸含量变异幅度为1.718～5.436 mg·g⁻¹；总黄酮含量变异幅度为0.780～1.457 mg·g⁻¹；重Ⅰ、Ⅱ、Ⅵ和Ⅶ含量变异幅度为0.008～2.106 、0.000～0.646 mg·g⁻¹、0.000～0.521 和0.000～9.170 mg·g⁻¹；华重楼根茎中总酚酸含量与原产地海拔、皂苷Ⅱ与1月均温呈中度正相关关系，总黄酮含量与全年日照时数、皂苷Ⅶ与海拔呈中度负相关关系。总皂苷与海拔间呈高度负相关关系，皂苷Ⅱ与年均温、皂苷Ⅵ与7月均温间均呈高度正相关关系；华重楼根茎中总酚酸与总黄酮含量、总黄酮与皂苷Ⅰ含量、皂苷Ⅰ与皂苷Ⅱ含量呈中度正相关关系，总皂苷与皂苷Ⅶ含量呈高度正相关关系。聚类分析表明，10个种源可以划分为3个类群，低酚酸、低黄酮和高皂苷类群，高酚酸、高黄酮、低皂苷类群和中酚酸、中黄酮、中皂苷类群。 结论 广西桂林为高酚酸和高黄酮优良种源，安徽祁门为高皂苷优良种源。

The study aims at compare and analyze the variation pattern of the phenotype characters and starch content of Quercus mongolica seed of different provenances. The length, width, length/width ratio, single kernel weight of Q. mongolica seeds from 16 natural distribution regions in China were measured and analyzed. The results showed that there were extremely significant differences among seeds from different region in seed characters. The length and width of seeds ranged from 14.76 mm to 21.08 mm and from 11.87 mm to 15.31 mm, respectively. The length/width ratio of seeds ranged from 1.21 to 1.49. The single kernel weight ranged from 0.60 g to 1.78 g and the contents of starch ranged from 4.42 g·kg-1 to 5.48 g·kg-1. The length of seeds has a extremely significant positive correlation with the width and weight of seed, and the width of seed had a significant positive correlation with the weight of seed. The seed width has a significant positive correlation with contents of starch. The width of seeds had a significant negative correlation with altitude, and had a positive correlation with July’s mean temperature. The weight of seed had a significant positive correlation with July's mean temperature too. The correlation of the other phenotypic character and starch content of Q. mongolica seed to geographical climate factors was not significant. According to the results of cluster analysis, sixteen Q. mongolica provenances could be divided into three groups with big fruit and high starch content, middle fruit and starch content, small fruit and low starch content, in which the provenances from Dailing of Heilongjiang Province, Benxi of Liaoning Province and Dayangshu of Inner Mongolia were the superior provenances.
