摘要
Striga asiatica (L.) O. Kuntze 是一种传统药用植物，富含黄酮类化合物，具有抗肝炎和抗氧化等多种药理作用。但由于资源匮乏，尚未实现人工栽培。本研究探讨了黄酮类代谢物与不同生境土壤理化性质和微量元素的关系，旨在为优质人工栽培茜草提供理论指导。研究结果表明，茜草对土壤肥力要求不高，喜欢在钾和可利用钾含量高，磷、氮和碱解氮含量低的酸性土壤中生长。此外，还从茜草中鉴定出 1592 种代谢物，其中包括 78 种黄酮类化合物。黄酮类代谢物与土壤因素密切相关。合理施用氮肥和钾肥，控制土壤中钠、锰和硼的含量，可以促进黄酮类代谢物在植物体内的合成。此外，山奈苷、甘草亭、叶黄素、芹菜素和染料木素可能是识别不同地区的代谢标记。
Effect of soil factors on flavonoid metabolites in Striga asiatica using LC–MS based on untargeted metabolomics
Background
Striga asiatica (L.) O. Kuntze is a traditional medicinal plant rich in flavonoids, which has various pharmacological effects such as anti-hepatitis and antioxidant activities. However, there is a scarcity of resources, and artificial cultivation has not yet been achieved. This study explored the association between flavonoid metabolites and soil physicochemical properties and trace elements in different habitats, with the aim of offering theoretical guidance for the high-quality artificial cultivation of S. asiatica.
Results
The results showed that S. asiatica has low requirements for soil fertility and prefers to grow in acidic soil with high contents of potassium and available potassium, while low contents of phosphorus, nitrogen and alkali hydrolyzed nitrogen. Additionally, 1592 kinds of metabolites were identified from S. asiatica, including 78 flavonoids.
Conclusions
The flavonoid metabolites were strongly related to soil factors. Reasonable application of nitrogen and potassium fertilizers as well as controlling the contents of sodium, manganese and boron in the soil, can promote the synthesis of flavonoid metabolites in the plant. Moreover, kaempferide, glycitein, luteolin, apigenin and genistein may be the metabolic markers for identifying different regions.
期刊介绍：
Chemical and Biological Technologies in Agriculture is an international, interdisciplinary, peer-reviewed forum for the advancement and application to all fields of agriculture of modern chemical, biochemical and molecular technologies. The scope of this journal includes chemical and biochemical processes aimed to increase sustainable agricultural and food production, the evaluation of quality and origin of raw primary products and their transformation into foods and chemicals, as well as environmental monitoring and remediation. Of special interest are the effects of chemical and biochemical technologies, also at the nano and supramolecular scale, on the relationships between soil, plants, microorganisms and their environment, with the help of modern bioinformatics. Another special focus is the use of modern bioorganic and biological chemistry to develop new technologies for plant nutrition and bio-stimulation, advancement of biorefineries from biomasses, safe and traceable food products, carbon storage in soil and plants and restoration of contaminated soils to agriculture.
This journal presents the first opportunity to bring together researchers from a wide number of disciplines within the agricultural chemical and biological sciences, from both industry and academia. The principle aim of Chemical and Biological Technologies in Agriculture is to allow the exchange of the most advanced chemical and biochemical knowledge to develop technologies which address one of the most pressing challenges of our times - sustaining a growing world population.
Chemical and Biological Technologies in Agriculture publishes original research articles, short letters and invited reviews. Articles from scientists in industry, academia as well as private research institutes, non-governmental and environmental organizations are encouraged.
