Phytochemical composition, total phenolic content and antioxidant activity of Anadara granosa (Linnaeus, 1758) collected from the east coast of South Sumatra, Indonesia

Abstract

Anadara granosa is a species of the class bivalve commonly found on the east coast of South Sumatra as a fishery commodity. This species has not been widely studied as a source of new bioactive compounds that have antioxidant abilities. This study aims to analyze the antioxidant ability of A. granosa against DPPH radicals and its phytochemical profile qualitatively. Samples were taken at the fishing port of Sungsang Village, South Sumatra, Indonesia. Furthermore, the samples were extracted using ethanol as a solvent and tested for antioxidants against DPPH radicals, total phenol analysis, and preliminary phytochemical test. Based on the antioxidant test results, the IC50 value of the ethanolic extract of A. granosa was 85 g/ml with ascorbic acid 2 g/ml as a comparison. Then, the ethanol extract contained a total of 10.7057 mgGAE/g phenol and the results of the phytochemical test contained bioactive compounds of alkaloids, steroids, flavonoids, saponins, and tannins. The ethanolic extract of A. granosa contained bioactive compounds, which were reported to have potent antioxidant activity. The results of this study were expected to be important information in the latest report of the antioxidant activity of A. granosa species and contributed to the development of marine natural products.

Antioxidant Activity, Total Phenolic, Phytochemical Content, and HPLC Profile of Selected Mangrove Species from Tanjung Api-Api Port Area, South Sumatra, Indonesia

“…Three species of mangrove leaves were taken as much as 500 g (dry weight) using an analytical scale (NIMBUS NBL254), which were mashed and macerated with 2 L of methanol (1:4 b/v) for 2 x 24 h. According to, 24 the methanol solvent was reported to be able to extract polyphenols and flavonoids at higher levels than other solvents. In line with research, 25 polar solvents tend to be able to extract more bioactive compounds. The success and efficiency of the method were determined by the type of solvent chosen.…”

An Assessment of Pb and Cu in Waters, Sediments, and Mud Crabs (Scylla serrata) from Mangrove Ecosystem Near Tanjung Api-Api Port Area, South Sumatra, Indonesia

“…Moreover, very alkaline or acidic pH conditions will be dangerous because they can cause metabolic and respiratory disorders (Pedapoli and Ramudu, 2014;Paran et al, 2022). Salinity is an essential factor for the spread of organisms in the sea, and oxygen is a limiting factor in determining the presence of organisms in the water (Nugroho et al, 2023). The variety of dissolved oxygen can be affected by waste materials or pollutants in the water.…”

Antibacterial Potential of Endophytic Fungi Isolated from Mangrove Rhizophora apiculata Blume Species at Tanjung Api-Api, South Sumatra, Indonesia

“…Based on geographic location, the sampling location was located in the intertidal area with coordinate positions S 2.3715833 and E 104.8041083 and had a fairly busy domestic port activity (Figure 1). This area has thick mud with fertile mangrove habitat and another benthic organism (4,16,17). This area is also influenced by the dynamics of water quality parameters, where it is a mixing area between a large mass of fresh water from the Banyuasin River and a mass of salt water from the Bangka Strait, forming a very large brackish area (18)(19)(20).…”
