Background : Morus alba L. (M. alba L.) belongs to the family Moraceae and has been industrially used as a food source for the silkworm and as a sedative in traditional medicine due to their adaptogenic, hypotensive, anti-inflammatory, hypoglycemic, and anti-adipogenic properties. In this study, metabolic profiling of diploid and tetraploid in Morus alba L. ‘Cheongil’
Methods and Results : Carotenoids are secondary metabolites found in most of the higher plants. In the current study, the levels of carotenoids were much higher in tetraploid of M. alba L. ‘Cheongil’ than diploid of M. alba L. ‘Cheongil’. Particularly, the levels of lutein, 13z-β-carotene, α-carotene, E-β-carotene, and 9Z-β-carotene were 2.51, 5.53, 7.68, 4.43, and 4,46 times higher in tetraploid of M. alba L. ‘Cheongil’, respectively. Additionally, hierarchical cluster analysis (HCA) was carried out using Pearson’s correlation results in order to determine the relationships between metabolites of diploid and tetraploid in Morus alba L. ‘Cheongil’. The results of HCA revealed the degree of correlation among 42 metabolites, which were identified and quantitated by GC-TOFMS. Among TCA organic acids, succinic acid was positively correlated with fumaric acid (r = 0.8250, p < 0.0001) and malic acid (r = 0.9436, p < 0.0001). Among carbohydrates, fructose was positively correlated with glucose (r = 0.9398, p < 0.0001) and mannose (r = 0.9394, p < 0.0001).
Conclusion : In this study, we investigated primary metabolites and secondary metabolites (carotenoids) in diploid and tetraploid in Morus alba L. ‘Cheongil’ in order to provide information on the difference between
