Jacaranda flower (Jacaranda mimosifolia) as an alternative for antioxidant and antimicrobial use

Abstract

Antimicrobial resistance to antibiotics is a serious health problem worldwide, for this reason, the search for natural agents with antimicrobial power against pathogenic microorganisms is of current importance. The objective of this work was to evaluate the antioxidant capacity (ABTS+ and DPPH), antimicrobial activity, and polyphenol compounds of methanolic and aqueous extracts of Jacaranda mimosifolia flowers. The antimicrobial activity against Bacillus cereus ATCC 10876 , Bacillus subtilis ATCC 6633 , Enterococcus faecalis ATCC 51299 , Escherichia coli ATCC 25922 , Listeria monocytogenes ATCC 19115 , Pseudomonas aeruginosa ATCC 27853 , Salmonella typhimurium ATCC 14028, Staphylococcus aureus ATCC 25923, and Streptococcus mutans ATCC 25175, was determined using the Kirby Bauer technique. The results of polyphenolic compounds showed a high amount of total flavonoids in the methanolic and aqueous extracts (503.3 ± 86.5 and 245. 7 ± 27.8 mg Rutin Equivalents/g DW, respectively). Quercetin, gallic acid, caffeic acid, and rutin were identified by the HPLC-DAD technique, while in the GC-MS analysis, esters, fatty acids, organic compounds, as well as monosaccharides were identified. Higher antioxidant capacity was detected by the ABTS technique (94.9% and 62.6%) compared to DPPH values (52.5% and 52.7 %) for methanolic and aqueous extracts, respectively. The methanolic extract showed a greater inhibitory effect on gram-positive bacteria, with a predominant higher inhibition percentage on Listeria monocytogenes and Streptococcus mutans (86% for both). In conclusion, Jacaranda flower extracts could be a natural antimicrobial and antioxidant alternative due to the considerable amount of polyphenolic compounds, and serve as a sustainable alternative for the isolation of active ingredients that could help in agriculture, aquaculture, livestock, pharmaceutics, and other industrial sectors, to remediate problems such as oxidative stress and antimicrobial abuse.

“…Серед видів фондової оранжереї тропіків і субтропіків багато рослин, що відповідають всім естетичним потребам людини, мають позитивний вплив на її здоров'я і працездатність і можуть бути використані для дизайну як відкритого, так і захищеного ґрунту. Велика кількість таксонів поєднує в собі одразу багато цінних ознак для людини: декоративність, фітонцидність, харчову цінність, лікарські властивості, у тому числі джерело антиоксидантів, тощо (Aguirre-Becerra et al, 2020, Domnytska et al, 2022. Серед таких більше 70 видів з 55 родів, що потребують охорони, це майже чверть від загальної кількості родин (28/105).…”

“…Las flores de la jacaranda tienen una alta cantidad de compuestos fenólicos, especialmente flavonoides como quercetina y rutina, en menor cantidad taninos, además de otros compuestos como ésteres, ácidos grasos, ácido erúcico, digitoxina, imidazol y α-tocoferol. Sutancias que en conjunto podrían ser las responsables de las actividades biológicas de esta especie, alta actividad antioxidante y antimicrobiana contra las bacterias Listeria monocytogenes y Streptococcus mutans (Aguirre et al, 2020).…”
