• Biochemical Analysis Under Heat Stress: Study investigated the differential expression of proteins and lipids produced by the tree under heat stress conditions. Several volatiles, isoprene, 2-methyl butanenitrile, ß-ocimene and a number of sesquiterpenes were produced under heat stress. Heat stress proteins, including heat shock proteins, histone proteins, oxygen evolving complex, and photosynthetic proteins were believed to play key roles in imparting thermotolerance. (7)
• Antifungal / Cytotoxicity / Fisetin / Fresh Xylem Sap: Study evaluated the cytotoxicity of fresh xylem sap of Hymenaea courbaril and fisetin against 3T3-A31 cells of Balb/c and for bioactivity against fungi Cryptococcus neoformans species complex and dermatophytes. Fisetin was filtered from the fresh xylem sap. The filtrate was a moisture of fistinediol, fustin, 3-O-methyl-2,3-trans-fustin and taxifolin. Results showed in vitro antifungal activity and low toxicity on animal cells. The xylem sap inhibited the growth of dermatophytes and C. neoformans with MIC of <256 µg/mL while fisetin showed MIC <128 µg/mL. Fisetine showed lower toxicity IC50 of 158 µg/ml compared to fresh xylem sap IC50 109 µg/ml. (8)
• Terpenoids / COX-2 and Lipid Peroxidation Enzyme Inhibition / Fruits: Study of fruit powder yielded sucrose and linolenic acid as major compounds. Pods yielded labdane diterpenoids. Total amounts of the terpenoids in the fruit was about 0.1% (w/w) of the dried fruit. Compound 3 and 4 showed selective COX-2 enzyme inhibition. Compounds 1, 2 and 5 inhibited lipid peroxidation by 46%, 48%, and 75%, respectively at 100 ppm. (see constituents above) (9)
• Antimicrobial / Fruit: Study evaluated the antimicrobial activity of H. courbaril against four bacteria, E. coli, S. aureus, B. subtilis and P. aeruginosa and fungi C. albicans and Saccharomyces cerevisiae and A. niger. The dichloromethane extract showed antimicrobial activity against Staphylococcus aureus with 1.47% inhibition. No inhibitory activity was seen against fungi. (10)
• Ultrasound-Assisted Extraction of Polyphenols / Increase Antioxidant Capacity / Bark: Study reports on the ultrasound assisted extraction of polphenols from bark. Water with S/F of 20 was the best solvent for extraction of phenolic compounds. Results showed a statistically significant (p<0.005) effect with approximately 15% increase in total phenolic compounds content when using maximum power. DPPH analysis confirmed the high antioxidant capacity of the ultrasound extracts. (11)
• Synergism with S. adstringens against -Assisted Extraction of Polyphenols / Increase Antioxidant Capacity / Bark: Study investigated the in vitro antimicrobial activities of H. courbaril and Stryphnodendron adstringens against clinical bacterial isolated. The crude extracts of both vegetal species showed bacteriostatic activity against almost all bacteria evaluated, with MIC ranging from 135-1250 µg/ml. The combination exhibited potent synergistic antimicrobial activity with MICs of 31.25 µg/ml against Acinetobacter baumannii, E. coli, and S. aureus. The synergism against resistant bacteria suggests potential for the development of new drugs. (12)
• Glycosylated Biscoumarins / Seeds: Study of seeds isolated two new biscoumarins from H. courbaril seeds. This was the first study for the purpose of identifying seed molecules. (see constituents above) (14)
• Myorelaxant Activity / Antioxidant / Anti-Inflammatory / Astilbin / Stem Bark: Astilbin is a flavonoid isolated from the bioactive ethyl acetate fraction of stem bark. Whole extract and some fractions strongly scavenged DPPH radical. The extract exhibited myorelaxant activity on rat trachea, with the EAF the most efficient fraction. Astilbin may be partly responsible for the myorelaxant effect of EAF. Results suggest potential antioxidant, myorelaxant and anti-inflammatory actions for the treatment of inflammatory airway disease. (15)
• Anti-Inflammatory on Pterygium Fibroblasts / Essential Oil: Study evaluated the anti-inflammatory effects of essential oil in pterygium genesis. Primary cultures of pterygium fibroblasts were exposed to H. courbaril essential oil. MTT test showed α-humulene, trans-caryophyllene and both together showed cytotoxic effect in concentration of 0.5 to 5 µM. The trans-caryophyllene compound from essential oil at 25 µM showed significant anti-inflammatory effect on IL-6 production of pterygium fibroblasts. Results suggest a potential alternative adjuvant agent in the treatment of pterygium. (see constituents above) (16)
