Abstract

The present study examines the dominant pigments in the surface and bulk of caimito (Chrysophyllum cainito L.) leaves using reflectance and transmittance spectroscopy. The leaves were characterized under the visible light region (400 nm − 700 nm) using spectrometer. Under this wavelength, different pigments were obtained specifically chlorophyll a, chlorophyll b and xanthophylls. Pigments like chlorophyll a were present in the different region in the reflectance and transmittance curve. These results was confirmed from the chromatographic analysis were chlorophyll and fucoxanthin are the dominant pigments. However, more intensive study is needed, specifically the use of higher region wavelength to identify further the pigments and properties of the leaf.
