The aim of the present study was to evaluate the in vitro antioxidant potential of the
hydroalcoholic extracts of flowers of Hibiscus cannabinus and Hibiscus diversifolius and leaves of
Flemingia macrophylla and Moringa oleifera. Samples were supplied by Epagri (Itajaí, Santa Catarina,
Brazil), were dried in an oven at 40-45 °C and were ground in a Willye TE-650 mill. Extracts were
prepared with 2 g of sample and 25 mL of ethanol:water (80:20, v:v), were heated in a water bath at 70 °C
for 30 minutes and filtered. In vitro antioxidant activity was determined using four assays: total phenolic
content by the Folin-Ciocalteau method (FC) [1], ferric reducing antioxidant power (FRAP) [2] and the
ABTS [3] and DPPH [4] free radical scavenging methods. Extracts were obtained in triplicate and analyzes
were developed in duplicate. Data were analyzed by ANOVA using the Statistica 8.0 software. Mean
separation was performed using the Tukey?s test at the 95% confidence interval (Table 1). As can be seen
in Table 1, all of the samples presented significant difference by the FC method and the highest total
phenolic content was obtained for the flowers of H. diversifolius. Moreover, this extract showed better
results in the other antioxidant assays when compared to the other samples. On the other hand, the lower
total phenolic content was observed for the leaves of M. oleifera. Despite this, this sample has similar
antioxidant activity to the leaves of F. macrophylla by the FRAP, ABTS and DPPH assays and to the
flowers of H. cannabinus by the ABTS method. On the whole, it is interesting to note that all plants are a
valuable source of natural bioactive molecules and has properties that suggest studies about their
phytochemical constituents. MenosThe aim of the present study was to evaluate the in vitro antioxidant potential of the
