Abstract

Research on red Pidada leaves (Sonneratia caseolaris L.) which is a mangrove plant with antioxidant potential has been carried out. This study aims to determine the simplicia characterization and activity of red Pidada leaf extracts and fractions as antioxidants. The results of the simplicia characterization were: water-soluble extract content of 11%, ethanol-soluble extract content of 16%, water content of 9%, ash content of 8.17%, and acid insoluble ash content of 0.48%. The antioxidant activity test was carried out using the DPPH (1,1-diphenyl-2-picrylhydrazyl) method. The antioxidant activity was determined by the IC50 (Inhibition Concentration) value. The results showed that the ethanol extract had an IC50 value of 24.22 ppm (very strong), n-hexane fraction 88.18 ppm (strong), ethyl acetate fraction 15.39 ppm (very strong), and ethanol fraction 38.41 ppm (very strong) Keywords: Sonneratia caseolaris L., antioxidants, DPPH, IC50

Abstract

Characterization is a step to determine the quality of an extract of natural materials, which includes specific, non-specific parameters, and phytochemical screening. This study aims to determine the specific, non-specific characteristics and secondary metabolite compounds of telang flower extract. Telang flowers are made into powdered simplisia, and the drying shrinkage is determined. Furthermore, extraction was carried out using the maceration method with 70% ethanol solvent. The drying shrinkage of the simplisia was 10% and the extract yield was 43.8%. Specific characterization results include organoleptic observations in the form of thick blue-black extract with a distinctive odor and bitter taste. The average content of soluble compounds in water is 58% and the average content of soluble compounds in ethanol is 17.67%. Non-specific characterization results include an average moisture content of 21.93%. Average ash content of 5% and acid insoluble ash content of 2%. The average specific gravity was 1.015 g/ml and the results of mold/chamir numbers were 1 × 102 colonies/g and total plate numbers were 1.3 × 103 colonies/g. Secondary metabolite compounds contained in telang flower extract include alkaloids, flavonoids, saponins, steroids and terpenoids.
