Comparative studies on chlorophyll concentration in some important plant families

Abstract

Chlorophyll is a notable green photosynthetic pigment found in cyanobacteria, algae, and higher plants. Chlorophyll manifests antioxidant, anti-cancerous properties, It also has a role in the food and pharmaceutical industries. The main objective of this research investigation is to compare the total chlorophyll content in some important plant families (Apocynaceae, Asteraceae, Euphorbiaceae, Fabaceae) and to make a comparative study on the concentration of chlorophyll as this bioactive compound has great importance in food and pharmaceutical industries. In the present study, chlorophyll was extracted from the leaves of ten plants from each family that are locally available, using 80% acetone and quantified by the Arnon method (1949) respectively. The final results revealed that Euphorbiaceae exhibited an enormous amount of average total chlorophyll. However, Catharanthus roseus from Apocyanaceae exhibited the highest concentrations of total chlorophyll.
