Abstract:
OBJECTIVE: To investigate the influence of UV-B induction on the content of secondary metabolites, three kinds of alkaloid especially, in post-harvest leaves of Mahonia bealei (Fort.) Carr.. METHODS: The HPLC chromatograms of secondary metabolites in leaves before and after UV-B induction were established, and the content changes of secondary metabolites were obtained by means of comparison and analysis. RESULTS: In comparison with the control group, the contents of the secondary metabolites after UV-B induction changed dramatically. The contents of jatrorrhizine and palmatine increased obviously and reached a plateau after UVB induction for six hours. The amplification of jatrorrhizine was 410.84% and that of palmatine reached 118.76%, but the content of berberine decreased obviously after induction. CONCLUSION: UV-B induction has remarkable effects on accumulation of secondary metabolites in postharvest leaves of Mahonia bealei (Fort.) Carr.
