Secondary Metabolite Analysis Of The Suspension Of Black Cumin Plant Cells (Nigella Sativa L.) Using Salicylic Acid
Unlocking the Secrets of Black Cumin: Secondary Metabolite Analysis of Suspension Cells Using Salicylic Acid
Introduction
The black cumin plant (Nigella sativa L.) has been a subject of interest for centuries due to its numerous health benefits, particularly its secondary metabolites that possess antioxidant and anti-inflammatory properties. These secondary metabolites are produced through a complex biochemical process in plants and have immense potential for the pharmaceutical and nutritional industries. In this study, we aimed to investigate the effect of salicylic acid on the growth and secondary metabolite production of black cumin plant cells in suspension culture.
Background
Secondary metabolites are a class of compounds produced by plants that are not essential for their growth and development but play a crucial role in their defense mechanisms and interactions with the environment. These compounds have been shown to possess various biological activities, including antioxidant, anti-inflammatory, and antimicrobial properties. The black cumin plant is a rich source of secondary metabolites, including thymoquinone, which has been shown to have potent antioxidant and anti-inflammatory effects.
Salicylic acid is a plant hormone that plays a key role in plant defense mechanisms and stress responses. It has been shown to stimulate the production of secondary metabolites in plants and has been used as a treatment to improve the quality and quantity of callus produced in tissue culture. In this study, we used salicylic acid as a treatment to investigate its effect on the growth and secondary metabolite production of black cumin plant cells in suspension culture.
Materials and Methods
This study was conducted at the Plant Network Culture Laboratory, Faculty of Agriculture and Phytochemical Laboratory, Faculty of Pharmacy, University of North Sumatra from February 2023 to July 2023. We used a Complete Random Design (RAL) to apply two factors of treatment that were repeated three times. The first factor was the concentration of PGR (Plant Growth Regulator) in MS media, which consisted of K0 (NAA 1 ppm + kinetin 0 ppm), K1 (NAA 0.5 ppm + kinetin 0.5 ppm), and K2 (NAA 1 ppm + 1 ppm kinetin). The second factor was the concentration of salicylic acid, namely M0 (salicylic acid 0 ppm), M1 (salicylic acid 0.5 ppm), and M2 (salicylic acid 1 ppm).
We observed several parameters in this study, including callus morphology, permanent cell volume (PCV), mounting cell volume (SCV), and analysis of secondary metabolites. The results showed that the combination of PGR NAA and kinetin and the combination of salicylic acid significantly affected all measured parameters. At concentrations of K1M1, K2M1, and K2M2, cell growth was optimizing with an average weight of 0.03 grams.
Results and Discussion
The results of this study showed that the combination of PGR NAA and kinetin and the combination of salicylic acid significantly affected all measured parameters. The combination of K1M1, K2M1, and K2M2 showed optimal growth, with an average weight of 0.03 grams. This finding provides an important insight into the effect of PGR and salicylic acid treatment on the growth of black cumin plant cells.
The use of salicylic acid in this study is an innovative approach, as this compound is known to stimulate the production of secondary metabolites. Salicylic acid functions as a signal in plants to increase the response to environmental stress and stimulate the mechanism of plant defense. Thus, combining salicylic acid with PGR such as NAA and Kinetin is expected to be able to improve the quality and quantity of callus produced, thus supporting the production of higher secondary metabolites.
Conclusion
This study shows the importance of regulating environmental factors and chemical treatment in plant tissue culture, especially in plants that have high economic value such as Nigella sativa L. The results of this study provide an important insight into the effect of PGR and salicylic acid treatment on the growth of black cumin plant cells. By understanding this interaction, researchers and practitioners can develop a more efficient tissue culture strategy to increase the production of bioactive compounds from black cumin plants.
Future Directions
Further research can be carried out to explore various concentrations and combinations of different treatments, as well as to understand the mechanism of action of these compounds in increasing the production of secondary metabolites. This study provides a foundation for future research in the field of plant tissue culture and secondary metabolite production.
