Abstract

This investigation aimed to identify the most favorable cultivar based on plant metabolites for potential targeted cultivation in the pharmaceutical industry. The analysis revealed the presence of 19 individual phenolics and 80 individual volatiles across the cultivars, a breadth of data not previously explored to such an extent. Flavones emerged as the predominant phenolic group in all mint-scented cultivars, except for peppermint, where hydroxycinnamic acids dominated. Peppermint exhibited high concentrations of phenolic acids, particularly caffeic acid derivatives and rosmarinic acid, which are known for their anti-inflammatory and antioxidant properties. Luteolin-rich concentrations were found in several mint varieties, known for their antioxidative, antitumor, and cardio-protective properties. Swiss mint and spearmint stood out with elevated levels of flavanones, particularly eriocitrin, akin to citrus fruits. Monoterpene volatiles, including menthol, camphor, limonene, and carvone, were identified across all cultivars, with Swiss mint and spearmint exhibiting the highest amounts. The study underscores the potential for targeted cultivation to enhance volatile yields and reduce agricultural land use. Notably, chocolate mint demonstrated promise for volatile content, while apple mint excelled in phenolics, suggesting their potential for broader agricultural, pharmaceutical, and food industry production.
双子叶植物中的薄荷香物种:丰富多样的酚类和挥发性化合物宝库
这项调查旨在根据植物代谢物确定最有利的栽培品种,以便在制药业中进行有针对性的栽培。分析结果表明,所有栽培品种中都含有 19 种酚类物质和 80 种挥发性物质,这些数据的广度是以前从未探究过的。黄酮类是所有薄荷香型栽培品种中最主要的酚类,但薄荷除外,其羟基肉桂酸占主导地位。薄荷表现出高浓度的酚酸,尤其是咖啡酸衍生物和迷迭香酸,它们具有抗炎和抗氧化的特性。在多个薄荷品种中发现了富含叶黄素的成分,它们具有抗氧化、抗肿瘤和保护心血管的功效。瑞士薄荷和留兰香的黄烷酮含量较高,特别是麦角苷,与柑橘类水果相似。在所有栽培品种中都发现了单萜挥发物,包括薄荷醇、樟脑、柠檬烯和香芹酮,其中瑞士薄荷和留兰香的含量最高。这项研究强调了有针对性种植的潜力,以提高挥发物产量,减少农业用地。值得注意的是,巧克力薄荷的挥发物含量很高,而苹果薄荷的酚类物质含量也很高,这表明它们在更广泛的农业、医药和食品工业生产中具有潜力。
