Research on the Influence of Cultivation Environment on the Active Ingredient Content and Physiological Response of Tongzi Yimicao

This study focuses on the effects of different cultivation conditions on the content of active ingredients and plant physiological changes in Leonurus japonicus . Tongzi Yimucao is a commonly used herbal plant in traditional Chinese medicine, commonly used to treat gynecological diseases. Its main active substances are leonurine and carnosine. Several factors in the cultivation environment can directly affect the synthesis and accumulation process of these components. In terms of water management, appropriate drought treatment can induce plants to accumulate more flavonoids and phenolic acids. Strong light conditions can stimulate laser interaction, indirectly enhancing the accumulation of active ingredients; Moderate temperature helps plants maintain metabolic balance, while too high or too low temperature may inhibit the synthesis of metabolites. Modern cultivation methods such as greenhouse planting and hydroponic technology can achieve more precise regulation of these environmental factors. Under controlled conditions, plant growth is more stable and the fluctuation of active ingredients is smaller. Environmental stress can cause changes in the antioxidant enzyme system within plants, such as increased activity of superoxide dismutase (SOD) and catalase (CAT). This type of reaction varies under different cultivation conditions, so it is necessary to design reasonable management measures in actual production. Future research can further combine precision agriculture equipment and molecular biology methods to reveal the relationship between environment and components at the genetic level, explore better cultivation schemes, and improve the quality and efficacy of Leonurus japonicus .
