The objective of present study was to establish and compare the contents of secondary metabolites of two Hypericum species, H. perforatum and H. maculatum, native to Lithuania, and to evaluate factors predetermining their variation with some practical implications for utilization and conservation. The HPLC analysis of the ethanolic extracts of the studied species showed some regularity in their composition. Both species contained chlorogenic acid, hyperoside, quercitrin, quercetin and hypericin. The presence of rutin and hyperforin was observed only in H. perforatum. The quantitative analysis showed higher content of quercitrin in H. perforatum, than in H. maculatum, whereas the differences in the contents of quercetin, hypericin and chlorogenic acid were not statistically significant between the species. H. maculatum contained a significantly higher content of hyperoside than H. perforatum. The data on phytochemical analysis suggest almost equivalent use of both H. perforatum and H. maculatum extracts in the food industry, cosmetics and pharmaceutics.
本研究的目的是建立并比较立陶宛本土的两种金丝桃属植物贯叶连翘和斑点金丝桃的次生代谢产物含量，并评估决定其变化的因素，为其利用和保护提供一些实际意义。对所研究物种的乙醇提取物进行的HPLC分析显示出其成分上的一些规律性。两种物种均含有绿原酸、金丝桃苷、槲皮苷、槲皮素和金丝桃素。仅在贯叶连翘中观察到芦丁和金丝桃素的存在。定量分析表明，贯叶连翘中槲皮苷的含量高于斑点金丝桃，而槲皮素、金丝桃素和绿原酸的含量在两种物种之间没有统计学上的显著差异。斑点金丝桃中金丝桃苷的含量明显高于贯叶连翘。植物化学分析数据表明，贯叶连翘和斑点金丝桃提取物在食品工业、化妆品和制药领域几乎具有同等用途。
