Effect of solid-to-solvent ratio on phenolic content and antioxidant capacities of Dukung Anak� (Phyllanthus niruri)

Wong B.Y., . and Tan C.P., . and Ho C.W., . Effect of solid-to-solvent ratio on phenolic content and antioxidant capacities of Dukung Anak� (Phyllanthus niruri). pp. 325-330. ISSN 22317546

The objective of this study was to evaluate the effects of solid-to-solvent ratio (1:5. 1:10 1:15 and 1:20) on the extraction of phenolic compounds (TPC and TFC) and antioxidant capacity (ABTS and DPPH radical scavenging capacity) of P. niruri. Solid-to-solvent ratio showed a significant effect for both phenolic compounds (TPC and TFC) and antioxidant capacity (ABTS and DPPH radical scavenging capacity) with 1:20 was the condition for extracting the highest of phenolic compounds (TPC and TFC) with a value of 5788.7 mg GAE/100 g DW and 1906.5 mg CE/100 g DW respectively and exhibited high antioxidant capacities (ABTS and DPPH radical scavenging capacities) with a value of 0.820 mM and 1.598 mM respectively among the four levels studied. TPC was positively and significantly correlated with ABTS and DPPH (r0.999 and r0.999) under the effects of solid-to-solvent ratio as compared to TFC positively and strongly correlated (r0.865 and r0.868) with ABTS and DPPH.

Abstract

The objective of this study was to evaluate the effects of solid-to-solvent ratio (1:5. 1:10 1:15 and 1:20) on the extraction of phenolic compounds (TPC and TFC) and antioxidant capacity (ABTS and DPPH radical scavenging capacity) of P. niruri. Solid-to-solvent ratio showed a significant effect for both phenolic compounds (TPC and TFC) and antioxidant capacity (ABTS and DPPH radical scavenging capacity) with 1:20 was the condition for extracting the highest of phenolic compounds (TPC and TFC) with a value of 5788.7 mg GAE/100 g DW and 1906.5 mg CE/100 g DW respectively and exhibited high antioxidant capacities (ABTS and DPPH radical scavenging capacities) with a value of 0.820 mM and 1.598 mM respectively among the four levels studied. TPC was positively and significantly correlated with ABTS and DPPH (r0.999 and r0.999) under the effects of solid-to-solvent ratio as compared to TFC positively and strongly correlated (r0.865 and r0.868) with ABTS and DPPH.
