The crude ethanol extracts of four Indonesian medicinal plants namely Curcuma xanthorrhiza Roxb.,Phyllanthus niruri Linn., Andrographis paniculata Ness., and Curcuma aeruginosa Roxb. wereexamined for their antioxidant (radical scavenging) activity using 2, 2-diphenyl-2-picrylhydrazyl(DPPH) free radical and cytotoxicity using brine shrimp lethality test (BSLT). The total phenoliccontent was used the Folin-Ciocalteu method. IC50 values for DPPH radical scavenging activityranged from 14.5 to 178.5 μg/ml, with P. niruri having the lowest value and therefore the mostpotent, and C. aeruginosa having the highest value. LC50 values for BSLT ranged from 210.3 to593.2 μg/ml, with C. xanthorrhiza and A. paniculata having the lowest and highest values,respectively. The total phenolic content of the Indonesian plants ranged from 133.0 ±3.7 to863.3±54.7 mg tannic acid equivalent per 1 g extract, with C. aeruginosa and P. niruri having thelowest and highest values, respectively. A positive correlation between free radical scavengingactivity and the content of phenolic compounds was found in the four of Indonesian medicinal plants.

Abstract Background: Increased exposure to pathogens and free radicals contributed to the high incidence and mortality rate of various cancers in Nigeria and globally. Promotion of scientific research on medicinal plants in collaboration with traditional health practitioners to validate claims made on safety, efficacy and quality of traditional medicinal plants in the treatment of cancer is imperative. This study aims at screening extracts of selected Nigerian medicinal plants used traditionally for cancer treatment for antioxidant, antimicrobial and cytotoxic activities towards identification of potential source of new anticancer agents.Methods: Twenty-one extracts from sixteen medicinal plants species were screened for their cytotoxicity on RD, HeLa and Hep-2 cancer cell lines using MTT assay. The DPPH radical scavenging activity of the extracts as well as their Total Phenolic Content (TPC) were evaluated. The extracts were also evaluated for their antimicrobial activity using spectrophotometric growth inhibition method. Results: Extracts of Tetrapleura tetrapleura and Xylopia aethiopica showed high DPPH inhibitory activity and phenolic content. Extracts of X. aethiopica and Anchomanes difformis showed broad spectrum of antibacterial activities while root extracts of Crotolaria retusa and T. tetraptera exhibited antifungal activities comparable (P<0.05) to Ketoconazole. Extracts of Capcicum frutescens, Aspilia africana, X. aethiopica, T. tetraptera and C. retusa showed broad spectrum of cytotoxic activities.Conclusions: Extracts of T. tetraptera and X. aethiopica demonstrated satisfactory activities in all the biological tests which could be linked to their high phenolic contents. The findings support the ethno-medicinal uses of most of the tested medicinal plants.

Natural antioxidant capacity of five important folk medicinal plants measured in vitro. Total phenolic content (TPC), flavonoid content (FC) and free radical scavenging capacity of ethanolic, methanolic and aqueous leaf extracts of Lippia alba (LA), Annona squamosa (AS), Hyptis suaveolens (HS), Commiphora wightii (CW) and Milletia pinnata (MP) was assessed using spectrophotometric method. Folin ciocalteu and aluminium chloride method employed to optimise TPC and FC. Free radical scavenging potentiality of leaf extracts was assessed using Ferrous ion chelation (FIC), 2, 2'-diphenyl-1-picrylhydrazyl (DPPH•) scavenging, Hydroxyl (OH•) radical scavenging (HRS) and Superoxide (O- 2) radical scavenging (SRS) methods. Results revealed that the TPC (96.22±5.85 to 519.23±34.90 ?g GAE/gm dry weight) were found significant in aqueous extracts from all the plants except AS (p<0.05). For FC (?g QCE/gm dry weight), ethanol was found optimum for LA (463.94±6.49), CW (289.99±2.70) and MP (347.47±4.50) whereas, aqueous was found more appropriate for rest two plants were found significant instead of ethanol and methanol (all p<0.05). The lowest IC50 (?g/ml) were recorded from A. squamosa (27.72±8.95), H. suaveolens (27.78±0.88), C. wightii (27.18±0.16) and M. pinnata (27.30±0.03). All plants have reflected a high antioxidant capacity; however, the highest antioxidant activity was reported from ethanolic extract of H. suaveolens followed by L. alba, A. squamosa, C. wightii and M. pinnata. Hence, these studies show that all folk medicinal plants contain potential antioxidant bioactive compounds.

All parts of N. nucifera are used as oriental medicine for various medicinal purposes. The aimed of this study was to determine phenolic compound and antioxidant activity of different parts of three lotus (N. nucifera including of Roseum Plenum (RP), Album Plenum (AP), and Hindu Lotus (HL)). Total phenolic content using Folin-Ciocalteu reagent method and free radical scavenging activities using DPPH assay were determined. Three deferent parts of lotus (leaves, stem, and flower) were determined. The result indicated that Roseum Plenum leaf showed the highest total phenolic contents and Roseum Plenum flower showed the highest antioxidant activities. Total phenolic content of different part of different of N. nucifera showed a significant difference (p < 0.05). It also was not uniform when compare between different of N. Nucifera. The results found that the total phenolic content was the opposite of antioxidant activity. This result may be attributed to antioxidant activity may not be from phenolic content. Therefore, it is important to research and develop the potential of lotus extraction in the future.

Several wild honey samples collected from seven different regions in Indonesia were investigated to determine their total phenolic content, flavonoid content, and free radical scavenging activity by analyzing the 1,1-diphenyl-2-picrylhydrazyl (DDPH) radical and phenolic profile. Rutin, (+)-catechin, ferulic acid, and galangin were found to be the major phenolic compounds of Indonesia wild honey. The total phenolic content significantly correlated with the total flavonoid content (p=0.000) and the percentage of DPPH radical scavenging activity (p=0.000). Results indicated that there are different polyphenol profiles among the different regions.
