“…However, the leaf extract of E. foetidum showed low efficiency in removing ABTS •+ (15.77 ± 0.92 μM Trolox/g, FW) when compared to Arrabidaea chica leaves (86.81 TE/g, FW). [23] This is the first time that the scavenging capacity of E. foetidum leaf extract against ABTS •+ was reported. The methanolic extract of E. foetidum leaves may also be able to capture DPPH • with inhibition percentage of 91.60 ± 0.45% at the tested concentration of 0.06 μg/g, a value similar to that found for the extracts of E. foetidum leaves previously reported by Singh et al, [7] (92.7%), but superior to the authors of a previous study (73.93%).…”

The quenching ability of E. foetidum leaf extract against singlet oxygen ( 1 O 2 ) was carried out according to the procedure described by Siqueira et al, [23] The extracts (125 to 600 μg/mL) and quercetin standard (positive control) (0.78 to 4.75 μg/mL) were tested at four concentrations. The kinetic data obtained from the decay intensity of TRP absorbance at 219 nm were fitted to a first order reaction (Eq.…”

Phenolic compounds and carotenoids profile of Amazonian Eryngium foetidum leaves and the quenching ability of their hydrophilic extract against singlet oxygen ( 1 O 2 ) were determined. Chlorogenic acid (4327 μg/g, dry basis, d.b.) was the major phenolic compound in the leaves at very high concentrations, while lutein (205 μg/g, d.b.) and β-carotene (161 μg/g, d.b.) were the major carotenoids. The extract of E. foetidum leaves was able to scavenge DPPH • (91.6% at 5 mg/mL), ABTS •+ (15.77 μM Trolox equivalent/g extract) and it exhibited high efficiency to protect tryptophan against 1 O 2 , with IC 50 at 343 μg/mL and 78% of protection at the highest tested concentration (625 μg/mL). Therefore, E. foetidum leaves can be exploited as an accessible natural source of bioactive compounds with antioxidant properties to be used by the food or pharmaceutical industries.

Therapeutic Potential of Leaves from Fridericia chica (Bonpl.) L. G. Lohmann: Botanical Aspects, Phytochemical and Biological, Anti-Inflammatory, Antioxidant and Healing Action

et al. 2022

View full text Add to dashboard Cite

Plants of the species Fridericia chica (Bonpl.) L. G. Lohmann (Bignoniaceae), which are widely distributed in Brazil and named crajiru in the state of Amazonas, are known in folk medicine as a traditional medicine in the form of a tea for the treatment of intestinal colic, diarrhea, and anemia, among other diseases. The chemical analysis of extracts of the leaves has identified phenolic compounds, a class of secondary metabolites that provide defense for plants and benefits to the health of humans. Several studies have shown the therapeutic efficacy of F. chica extracts, with antitumor, antiviral, wound healing, anti-inflammatory, and antioxidant activities being among the therapeutic applications already proven. The healing action of F. chica leaf extract has been demonstrated in several experimental models, and shows the ability to favor the proliferation of fibroblasts, which is essential for tissue repair. The anti-inflammatory activity of F. chica has been clearly demonstrated by several authors, who suggest that it is related to the presence of 3-deoxyanthocyanidins, which is capable of inhibiting pro-inflammatory pathways such as the kappa B (NF-kB) nuclear transcription factor pathway. Another important effect attributed to this species is the antioxidant effect, attributed to phenolic compounds interrupting chain reactions caused by free radicals and donating hydrogen atoms or electrons. In conclusion, the species Fridericia chica has great therapeutic potential, which is detailed in this paper with the objective of encouraging new research and promoting the sum of efforts for the inclusion of herbal medicines in health systems around the world.

“…The 1 O 2 -quenching capacity of the A. amazonicum extracts (and positive control) was determined according to the procedure described in details by De Siqueira et al (2019). Briefly, 1 O 2 was generated by sensitization of MB using an incandescent lamp of 75 W as the excitation source, Ltryptophan (TRP) was the reaction actinometer and all the reactants were diluted in phosphate-buffered saline (pH 7.2) solution.…”

Antrocaryon amazonicum fruits are unexploited sources of bioactive compounds found in the Amazonia region of Brazil. In this study, for the first time, the carotenoid and phenolic compound profiles of the pulp and peel of A. amazonicum fruits, from two varieties at two harvest periods, were determined by LC-MS. Additionally, the potential of the peel and pulp extracts to scavenge physiologically relevant reactive oxygen species (ROS) and reactive nitrogen species (RNS) was assessed. The major carotenoids in both parts of the fruits were lutein, accounting for ≈42% of the identified carotenoids in the peel and ≈25% in the pulp, whereas catechin and hydroxybenzoic acid derivatives were the major phenolics in both parts. The peel extract, which presented the highest bioactive compound contents, was more efficient to scavenge ROS than the pulp.The peel extract showed high scavenging efficiency (IC 50 ) for singlet oxygen ( 1 O 2 ; 16 µg/ml), hypochlorous acid (HOCl; 20 µg/ml), peroxynitrite (ONOO -; 38 µg/ml), and superoxide radical (O 2•-; 47 µg/ml), whereas the pulp extract exhibited high efficiency for ONOO -(13 µg/ml), followed by HOCl (30 µg/ml), źO 2 (76 µg/ml), and less efficient for O 2 •-(44 µg/ml). Therefore, A. amazonicum fruits can be seen as an expressive source of bioactive compounds with high antioxidant potential to be further investigated to inhibit or delay oxidative processes both in food and physiological systems triggered by ROS and RNS. Practical Application: Bioactive compound extracts of Antrocaryon amazonicum fruits have high potential to be exploited for inhibiting or delaying oxidative processes and increase food stability.
