Promising antioxidant activity of crude extract from Calliandra tweedii Benth

The interest in medicinal plants encourages new research studies on plant extracts, as they are sources for treatments medicine, agriculture, and veterinary. Calliandra tweedii is a native Brazilian species with broad use folk medicine. This study aimed to examine the leaf crude extract (CE) of C. its methanolic (MP) hexane (HP) phases concerning total phenolic compounds (TPC), proanthocyanidins (PRO), flavonoid profile, correlate it their antioxidant activity (DPPH FRAP). CE MP revealed high contents TPC, PRO FRAP) relation HP. Contrarily, HP showed reduced activity, according scarce constituents obtained from partition. Five flavonols were detected by HPLC-UV-DAD, being quercitrin major constituent. Also, one kaempferol derivate series three quercetin derivates detected. Strong positive correlations observed between DPPH, FRAP, compounds. These discoveries important highlight promising tweedii, which could contribute expansion popular herbal medicines drug discovery.
