Phytochemical screening, phenolic and flavonoid content, and antioxidant activity of Rhizophoraceae methanol extracts from Langsa, Aceh, Indonesia

Abstract. Indriaty, Djufri, Ginting B, Hasballah K. 2023. Phytochemical screening, phenolic and flavonoid content, antioxidant activity of Rhizophoraceae methanol extracts from Langsa, Aceh, Indonesia. Biodiversitas 24: 2865-2876. Bruguiera cylindrica (L.) Blume,Bruguiera gymnorrhiza Lam., Ceriops decandra (Griff.) Ding Hou, Rhizophora apiculate Blume, mucronata Lam. are mangrove plant species belonging to that have been used as medicinal plants. Studies on phytochemical screening bioactivity plants the Aceh region still limited. This study aimed analyze chemical compounds in determine total content (TPC), (TFC), activity. The were determined using qualitative assay, TLC, Gas Chromatography-Mass Spectrophotometry (GC-MS). was tested against 2,2-diphenyl-1-picrylhydrazyl (DPPH). Twenty various parts (roots, bark, leaves, fruit/hypocotyl) this study. revealed presence alkaloids, flavonoids, phenolics (tannins), terpenoids, steroids, saponins. highest TPC obtained bark R. (484.39 mg GAE/g extract). Furthermore, TFC found leaves apiculata ( 15.23 QE/g Nineteen had very high (IC50: 2.35 ± 0.01 - 29.84 0.19 µg/mL). roots C. most potent 3.23 µg/mL, respectively). GC-MS pyrocatechol (15.85%), antiarol (1.44%), hexadecanoic acid (1.69%), act antioxidants. Therefore, it can be concluded extract contains phenols stem flavonoids with a good source natural ingredients for future pharmaceutical product development. It is highly recommended do further research obtain pure these
