Comparative Analysis of Primary and Secondary Metabolites in Different In Vitro Tissues of Narcissus tazetta var. chinensis
Abstract
Narcissus tazetta var. chinensis is a perennial monocot plant that is well known for its pharmaceutical and ornamental uses. This study aimed to understand the changes in the primary and secondary metabolites in different in vitro tissues of N. tazetta (callus, adventitious root, and shoot) using high-performance liquid chromatography and gas chromatography time-of-flight mass spectrometry. In addition, to optimize the most efficient in vitro culture methods for primary and secondary metabolite production, N. tazetta bulbs were used as explants and cultivated in Murashige and Skoog (MS) medium containing different hormones at various concentrations. In addition, the present study found suitable hormonal concentrations for callus, adventitious root, and shoot induction and analyzed the primary and secondary metabolites. The MS medium supplemented with 1.0 mg L–1 dicamba, 3.0 mg L–1 indole-3-butyric acid (IBA), and 3.0 mg L–1 6-benzylaminopurine (BAP) was the most efficient media for callus, adventitious root, and shoot induction in N. tazetta. The tissue induced in this medium was subjected to primary (amines, amino acids, organic acids, sugars, and sugar alcohols) and secondary metabolite (galantamine and phenolic acids) analysis. The shoots and roots showed the highest amounts of metabolites. This study showed that bulb in vitro culture can be an efficient micropropagation method for N. tazetta and the production of primary and secondary metabolites, offering implications…
