Polyphenolic Profiling in Ajuga reptans and Salvia miltiorrhiza Tissue Cultures Dictates Somatic

* *Polyphenolic Profiling in Ajuga reptans and Salvia miltiorrhiza Tissue Cultures Dictates Somatic Embryogenesis and Tissue Culture Contamination Control**

* *Abstract**

Ajuga reptans and Salvia miltiorrhiza are two important medicinal plants used in traditional medicine for their antioxidant and anti-inflammatory properties. In vitro tissue culture is a valuable tool for the mass production of these plants, but contamination remains a significant problem. This study investigated the role of polyphenolic and flavonoid compounds in preventing contamination and enhancing somatic embryogenesis efficiency in Ajuga reptans and Salvia miltiorrhiza tissue cultures using HPLC-MS/MS and qPCR analysis. Our results show that both plants contain a range of polyphenolic compounds, including flavonoids, phenolic acids, and lignans, which are involved in antioxidant activity and redox balance. We also found that these compounds are associated with reduced contamination risk and enhanced somatic embryogenesis efficiency. Our study provides new insights into the role of polyphenolic compounds in the conservation of medicinal plant biodiversity and the development of sustainable in vitro tissue culture systems.

* *Introduction**

Ajuga reptans and Salvia miltiorrhiza are two important medicinal plants used in traditional medicine for their antioxidant and anti-inflammatory properties. Ajuga reptans is also used as a natural food additive and flavoring agent, while Salvia miltiorrhiza is used to treat cardiovascular diseases and degenerative cognitive disorders. In vitro tissue culture is a valuable tool for the mass production of these plants, but contamination remains a significant problem. This is due to the presence of microorganisms such as bacteria, fungi, and viruses, which can cause damage to the plant cells and lead to the loss of valuable plant material.
