Abstract. Murningsih T, Praptiwi, Liana, Fathoni A. 2019. TLC profiling and antioxidant activity of phenolic compound from Sterculia oblongata bark extract. Nusantara Bioscience 11: 44-48. In the present study, we investigated the total phenolic content and in- vitro antioxidant activity of Sterculia oblongata. Total phenolic content (TPC) of the methanol extract was examined by Folin-Ciocalteu reagent and gallic acid as standard. The in-vitro antioxidant activity was performed by DPPH free radical scavenging activity and β-carotene bleaching assay. The result showed that the TPC of methanol extract was the highest (P<0.05) compared to other extracts. There is a positive and significantly very high Pearson’s correlation between antioxidant activity index (AAI) and TPC (r = 0.996). A negative and significantly high Pearson’s correlation was obtained between IC50 value and TPC (r = -0.885). The result of β-carotene bleaching assay showed that the rate of the decreased antioxidant activity of S.oblongata extract was lower than that of β-carotene/linoleic acid. The results suggest that the extract of S. oblongata can be used as a natural antioxidant. However, further investigation to isolate and identify the chemical compounds responsible for antioxidant was needed

<p>The objective of present study was to evaluate preliminary phytoconstitutents and <em>invitro</em> antioxidant potential of <em>Pentatropis nivalis </em>(Asclepiadaceae). During the preliminary phytochemical analysis, methanolic and aqueous extracts of aerial part of <em>Pentatropis nivalis</em> was screened for the presence of phenolic, saponins, flavonoids, alkaloids, tannins and phytosterols. TLC of extracts were performed by using various solvent systems. Phytochemicals screening and TLC spots of MEPN and AEPN showed the presence of glycoside, steroids, terpenoids, phenolic, saponins, Methanolic extract showed better qualitative tests for presence of secondary metabolites than aqueous extract.The in-vitro antioxidant potential of extracts were evaluated by DPPH and FRAP, and both methods showed that the plant possesses good antioxidant activity.</p>
