The galactomannans showed an efficient water holding capacity, solubility, and emulsion properties.. Results suggest the seed galactomannans could be explored as an effective alternativ3e3 to commercial galactomannans for industrial applications. (34)
Antifeedant / Pesticide / Pomacea canaliculata / / Seeds: Pomacea canaliculata is a dangerous pest to paddy field due to fast eating of stem and young leaves of paddy. Use of synthetic pesticides have a negative impact to natural environment. Study evaluated P. pterocarpum and Ipomoea aquatica extracts for antifeedant activity to control O. canaliculata. All treatments gave high amounts of lupeol compared with catechin, rutin, salicylic acid, quercetin and kaempferol. Peltophorum pterocarpum methanol extracts showed highest antifeedant index (AFI: 46.9%) compared to other treatments. Results recommend P. pterocarpum as an alternative botanical pesticide due to its antifeedant properties on P. canaliculata. (35)
Antimicrobial / Antioxidant / Cytotoxicity: Study evaluated the antimicrobial activity, acute toxicity, antioxidant activity and cytotoxicity of P. pterocarpum. Pet-ether, ethyl acetate and water extracts showed pronounced antimicrobial activity against both gram-positive and gram negative bacteria and fungus. Acute toxicity testing of flowers, leaves, and bark showed them to be free from toxic effects Antioxidant screening using DPPH assay showed various parts with pronounced antioxidant activity. In cytotoxicity testing, the ethanol crude extracts showed mild cytotoxic effect n colon cancer stem cells and human lung fibroblast.    (37)
Antiplasmodial / Hematopoietic / Stem Bark: Study evaluated the antimalarial activity of methanol extract of P pterocarpum stem bark and its amelioration of plasmodium-induced changes in hematological indices in Plasmodium berghei infected mice. Phytochemical screening yielded alkaloids, flavonoids, saponins, terpenoids, tannins, carbohydrates, fats and oils, reducing sugars, phenols, resins, protein and steroids. No clinical signs nor mortality was noted 24 hours after a dose of 5000 mg/kbw. Treated of infected mice reduced percentage malaria parasitemia in a dose-dependent manner and restored hematological changes produced by infection. (38)
Membrane Stabilization / Antioxidant / Protease Inhibition / Stem Bark: Study evaluated the membrane stabilization, albumin denaturation, protease inhibition and antioxidant activities and possible mechanisms for anti-inflammatory effects of stem bark of flavonoid-rich extract of P. pterocarpum (FREPP). FREPP inhibited hypotonicity-induced hemolysis by 61.03%, 76.84%, and 83.84% at 0.1, 0.4, 0.8 mg/mL, respectively. FREPP effectively inhibited albumin denaturation in a concentration dependent manner. Protease activity was significantly reduced (p<0.05) across varying concentrations. Results suggest FREPP has antioxidant and anti-inflammatory activities, which may be attributed to its rich flavonoid contents to inhibit membrane, albumin denaturation and protease activity. (39)
Antimicrobial / Antioxidant / Flowers, Leaves and Bark: Study of petroleum ether and ethyl acetate crude extracts of flowers yielded physcion (1), ß-sitosterol (2), naringenin (3), gallic acid (4), bergenin (5), and 11-O-acetylbergenin (6). All crude extracts exhibited zones of inhibition ranging from 12-20mm against six test microorganisms viz. B. subtiis, B. pumilus, S. aureus, P. aeruginosa, C. albicans and E. coli.
