The present study aimed to investigate the influence of different growing conditions on the amount of leaf pigments (chlorophylls, carotenoids), bioactive metabolites, such as polyphenols, flavonoids, lawsone and volatile organic compounds (VOCs) of L. (henna) plants. Young henna plants were cultivated for two months in a growth chamber (GC) and in open-air conditions during summer under the Mediterranean climate (OF), and leaves were analysed to evaluate their adaptive responses. The different growth conditions modified the carbon allocation priorities, increasing antioxidant metabolites (e.g. phenolic and flavonoid compounds) while decreasing lawsone in GC conditions. Quali-quantitative changes were observed for VOCs. This study revealed that GC conditions permit an alternative use of cultivation, because of the increase in the endogenous content of bioactive secondary metabolites with many potential biological activities.
本研究旨在探讨不同生长条件对 L.（指甲花）植物叶片色素（叶绿素、类胡萝卜素）、生物活性代谢物（如多酚、类黄酮、胡桃醌和挥发性有机化合物[VOCs]）含量的影响。将年轻的指甲花植物在生长室（GC）中培养两个月，并在夏季在地中海气候下露天条件（OF）下种植，分析叶片以评估其适应反应。不同的生长条件改变了碳分配的优先级，增加了抗氧化代谢物（如酚类和类黄酮化合物），而在 GC 条件下减少了胡桃醌。VOCs 观察到了定性和定量的变化。本研究表明，GC 条件允许对栽培进行替代使用，因为增加了具有许多潜在生物活性的内源性生物活性次生代谢物的含量。
