* *Phytochemical Responses of Medicinal Plant Hybrids to Hydrothermal Mineralization on Basaltic Substrates**

* *Abstract**

Hybridized Angelica archangelica and Ligusticum chuanxiong, two elite medicinal plant cultivars, were subjected to prolonged water immersion in the presence of contrasting geological substrates. This study aimed to investigate the bioactive compound profiles and root morphological adaptations of these plants in response to hydrothermal mineralization on basaltic substrates. Our results show that plants grown on hydrothermally altered basaltic substrates exhibit enhanced bioactive sesquiterpenes and phenolic compounds, which are associated with improved medicinal properties. We also observed significant root morphological adaptations, including UPC (unit plant conductance) increase, root growth enhancement, and increased rhizome production. GC-MS and HPLC analysis of phytochemical profiles revealed significant correlations between specific compounds and substrate type. Our findings suggest that hydrothermal mineralization on basaltic substrates can be used as a novel approach to enhance the medicinal properties of Angelica archangelica and Ligusticum chuanxiong.

* *Introduction**

Medicinal plants have been used for centuries to treat various diseases and ailments. However, the complexity of plant biology and the variability of growing conditions can lead to inconsistent quality and efficacy of medicinal plant products. Hydrothermal mineralization, a process that involves the interaction of water and heat with geological substrates, has been shown to modify the chemical composition of substrates and affect plant growth and development. In this study, we investigated the phytochemical responses of hybridized Angelica archangelica and Ligusticum chuanxiong to hydrothermal mineralization on basaltic substrates.

* *Methods**

Two elite medicinal plant cultivars, Angelica archangelica and Ligusticum chuanxiong, were grown in a controlled environment chamber with a temperature range of 20-25°C and a photoperiod of 16 hours. Plants were subjected to prolonged water immersion in the presence of contrasting geological substrates, including granite and basaltic substrates. The hydrothermal mineralization process was conducted at a temperature of 70°C for 24 hours. Plant growth and development were monitored over a period of 6 weeks. Phytochemical profiles were analyzed using GC-MS and HPLC.

* *Results**

Our results show that plants grown on hydrothermally altered basaltic substrates exhibit enhanced bioactive sesquiterpenes and phenolic compounds, which are associated with improved medicinal properties. We also observed significant root morphological adaptations, including UPC (unit plant conductance) increase, root growth enhancement, and increased rhizome production. GC-MS and HPLC analysis of phytochemical profiles revealed significant correlations between specific compounds and substrate type.

* *Key Findings**

1. Plants grown on hydrothermally altered basaltic substrates exhibit enhanced bioactive sesquiterpenes and phenolic compounds.

2. Significant root morphological adaptations were observed, including UPC (unit plant conductance) increase, root growth enhancement, and increased rhizome production.

3. GC-MS and HPLC analysis of phytochemical profiles revealed significant correlations between specific compounds and substrate type.

* *Botanical Mechanisms**

The observed phytochemical responses of Angelica archangelica and Ligusticum chuanxiong to hydrothermal mineralization on basaltic substrates can be attributed to the modification of the chemical composition of the substrate. The interaction of water and heat with the basaltic substrate leads to the release of ions and minerals, which are then absorbed by the plant roots. This process triggers a series of biochemical reactions that result in the production of bioactive compounds.

* *Diagnostic Thresholds/Assay Caveats**

The diagnostic thresholds for detecting bioactive compounds in plant extracts are not well established. The assay methods used in this study, including GC-MS and HPLC, are commonly used in the analysis of plant extracts. However, the accuracy and reliability of these methods depend on various factors, including the quality of the plant material, the extraction method, and the instrument calibration.

* *Practical Implications**

The findings of this study have significant practical implications for the cultivation and production of medicinal plants. The use of hydrothermal mineralization on basaltic substrates can be used as a novel approach to enhance the medicinal properties of Angelica archangelica and Ligusticum chuanxiong. This method can be used to improve the quality and efficacy of medicinal plant products, which can lead to better health outcomes for patients.

* *Limitations**

This study has several limitations. The experiment was conducted in a controlled environment chamber, which may not accurately reflect the conditions found in the field. The sample size was also limited, which may not be representative of the entire population. Additionally, the study only investigated two elite medicinal plant cultivars, which may not be representative of other plant species.
