Compare the Chlorophyll Amount in Three Brown Algae Species of the Persian Gulf by Using Three Solvents and Applying Two Formulas

摘要

Chlorophyll is the green pigment in plants that helps to absorb sunlight and converts it into energy. It is believed that it is beneficial for the human body. Therefore in this study, the chlorophyll amount in three brown algae species (iSirophysalis trinodis, Polycladia myrica/i and iColpomenia sinuosa/i) of the Persian Gulf by using three solvents and applying two formulas was compared. Acetone, diethyl ether and methanol were used as solvents. Results showed that the chlorophyll amount in different species dependent on solvent type and cell wall structure of algae. The highest chlorophyll a and x+c contents were observed in iS. trinodis/i species. Also, the highest content of chlorophyll csub1/sub+csub2/sub was showed in iC. sinuosa/i by the extraction with diethyl ether solvent. In both formulas was no significant difference between the same solvents in the amount of chlorophyll a. In general, the aim of this study due to the diversity and dispersion of algae and also their potential use in the food industry, cosmetics and pharmaceutical goods was to choose a suitable solvent for better extraction of chlorophyll as an active ingredient. Hence, in this study, the acetone was a better solvent.
