SPECTROPHOTOMETRIC DETERMINATION OF CHLOROPHYLLS AND CAROTENOIDS OF SOME BRYOPHYTE SPECIES USING DIFFERENT SOLVENTS
The role of photosynthetic pigments in plants is vital, and solvent selection significantly impacts their quantification. This study aimed to evaluate the influence of solvent selection on the efficiency of pigment extraction in bryophytes. Samples were collected from five locations in Ojo Local Government, Lagos State, Nigeria, and subjected to extraction using ethanol, methanol, acetone, dimethyl sulphide, and diethyl ether. Spectrophotometric analysis quantified chlorophyll a, chlorophyll b, total chlorophyll, and carotenoids, using specific wavelengths for each solvent. Data was analyzed with Statistix 10.Results showed significant variations in chlorophyll a, chlorophyll b, total chlorophyll, and carotenoid concentrations across the locations. Methanol consistently yielded the highest pigment extractions, while diethyl ether showed the least efficiency. Additionally, location-dependent variations in pigment content highlighted the sensitivity of extraction to environmental factors. The study emphasized the critical role of solvent selection, with methanol demonstrating superior and consistent performance.It is recommended that future studies adopt methanol as the preferred solvent for bryophyte pigment extraction and further investigate carotenoid stability and extraction efficiency under varying environmental conditions.
