Assessment of in vitro antioxidant capacity and polyphenolic composition of selected medicinal herbs from Leguminosae family in Peninsular Malaysia
Abstract
Determination of total phenolic (TPC), flavonoid and anthocyanin contents, and various antioxidant activities (2,2-diphenyl-1-picrylhydrazyl radical scavenging, ferric reducing power, ferrous ion chelating and lipid peroxidation inhibition) of leaves and flowers of Bauhinia kockiana, Caesalpinia pulcherrima and Cassia surattensis were performed in this study. The B. kockiana flower was found to possess the highest TPC (8280±498mgGAE/100g), free radical scavenging activity (ascorbic acid equivalents 14,600±2360mgAA/100g) and reducing ability (72.4±8.7mgGAE/g). Rutin and chlorogenic acid were detected in the plants, where the C. pulcherrima leaf contained the highest amount of rutin (669±26mg/100g), while minute amounts of chlorogenic acid were detected in C. surattensis leaf (9.13±0.44mg/100g). The C. pulcherrima leaf displayed the highest ferrous ion chelating and lipid peroxidation inhibition activities. Positive correlation was observed between TPC and various antioxidant activities.

An earlier report showed high anthocyanins content in B. kockiana flowers.
“Our earlier report [4] showed the presence of high anthocyanins content in B. kockiana flowers.”
A previous study showed that rutin was present in C. surattensis flowers and leaves extracts at 13.3 mg rutin equivalent/100 g and 29.6 mg rutin equivalent/100 g, respectively.
“Our previous study [4] has shown that rutin was present in C. surattensis flowers and leaves extracts (13.3 mg rutin equivalent/100 g and 29.6 mg rutin equivalent/100 g, respectively), assessed using aluminium chloride method.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
