In in-vitro study, porcine coronary artery showed a vasodilation effect induced by DRLE in a dose-dependent manner. Cardioprotective effect was attributed through activation of vasodilation through the NO pathway and prevention of myocyte injury via inhibition of TNF-alpha pathway. (34)

• Analgesic / Antimicrobial / Leaves: Study of ethanolic extract of leaves of Delonix elata and Delonix regia showed good antimicrobial activity (40 mg/10 ml) and analgesic activity at dose of 200 mg/kbw. The ethanolic extract of plants showed mild to moderate antimicrobial activity against E. coli, S. aureus, P vulgaris, P. aeruginosa and Aspergillus niger, with streptomycin and nystatin as standard drugs. Analgesic activity was carried out using tail flick method. (44)
• Edibility of Seed and Seed Oil: Delonia regia leaves, roots, and seeds have been extensively used for the treatment of many ailments but only the immature seeds have been found edible. The mature seeds are reportedly toxic due to antinutrient contents. This study investigated the proximate, amino acid, and vitamin composition of mature seeds and characterized the seed oil for fatty acids, acylglycerols. Study concludes the seeds are a good source of oil, energy-rich, good for consumption and can be used as protein supplement but may pose cardiovascular risk because of its hight sodium-to-potassium ration. The seed oil contains essential fatty acids, acylglycerols and viramins needed for nutrition and production of soaps, shampoos, and as biodiesel feedstock. (see constituents above (45)
• Effect on Liver Enzyme Markers and Electrolytes / Alloxan-Induced Diabetic Rats: Study evaluated the effect of seed extract of D. regia on some liver enzyme markers and electrolytes in alloxan-induced diabetic albino rats.

(46)
Carboxymethylated Seed Gum: Hydrocolloids or gum are widely used in the food industry as emulsifying, stabilizing, thickening, gelling and film-forming agents. Study searched for new species of gums and hydrocolloids that can compete with those in traditional use, such as flamboyant (Delonix regia) seed gum, an ornamental and underutilized species. Flamboyant tree seeds yielded a native gum (flamboyant gum which was modified by carboxymethylation. Results suggest a product with gum functionality with versatile potential for use in the food industry. (47)
Removal of Toxic =Pb (II) Ions / Pod: Study evaluated the removal of toxic heavy metal PB2+ ions from aqueous solution by agricultural biosorbents using nano sized Delonix regia. Results showed D. regia is an available agricultural, low cost and environment friendly and effective biosorbent for removing PB2++ ions. (48)
