Differences of secondary metabolites content in Kasturi Mango (Mangifera casturi Kosterm.) from South Kalimantan by the application of artificial light using light emitting diode

Abstract

Mango (Mangifera casturi Kosterm.) is one of the endemic plants of South Kalimantan, which is known to have a long juvenile phase. Applying light to plants will affect plant morphology and physiology changes. The provision of LED light as artificial light is known to modify plant metabolites. This research aims to determine changes in the response effects of the addition of artificial light using red, blue, and white monochromatic LEDs on secondary metabolite profiles in Kasturi mango seedlings from three Kasturi accessions: Mawar, Pelipisan, and Kasturi. Secondary metabolites were measured using the GC/MS and LC/MS methods. Profiling of metabolites using the GC/MS method resulted in 18 secondary metabolites, with the common compounds belonging to the sesquiterpenoid group. The Pelipisan accession contains unique compounds from the steroid group with different abundances for each type of LED lamp used. Estimating secondary metabolites using the LC/MS method obtained results of 10 compounds consisting of alkaloids, phenolics, antioxidants, and flavonoids.
