| Summary: | Biflavonoids are an important group of flavonoids found in <i>Juniperus</i> species, yet their distribution and accumulation patterns remain insufficiently explored. In this study, we applied a method for the simultaneous quantification of seven biflavonoids to analyze different plant parts of <i>J. communis</i>, <i>J. communis</i> subsp. <i>nana</i>, and <i>J. oxycedrus</i>. In order to determinate the influence of growing location, we also analyzed <i>J. communis</i> samples collected from different locations. Four biflavonoids—cupressuflavone, amentoflavone, bilobetin, and hinokiflavone—were detected. In both analyzed <i>J. communis</i> varieties, amentoflavone was the predominant biflavonoid in cones and needles, while in <i>J. oxycedrus</i>, cupressuflavone was the most abundant in cones, with amentoflavone dominating in needles. Overall, biflavonoid content was significantly higher in needles than in cones, with total biflavonoid levels in needles exceeding 5 mg/g dw, highlighting the tissue-specific nature of biflavonoid biosynthesis within <i>Juniperus</i> species. Additionally, our results suggest that in <i>J. communis</i>, biflavonoid accumulation is significantly influenced by growing location. |
