“…Phenolic content in above-ground part of I. pumila was similar to result obtained for Tossa jute leaves. [46] In the case of flavonoids, a similar distribution was recorded as for total phenolic content -I. variegata possessed maximal amounts of flavonoids in green part (4.0 mg QE/ g) while I. humilis flowers, again, have shown the lowest flavonoids content (0.79 mg QE/g of dry weight). TFC in above-ground part of I. variegata was in accordance with results for ethanolic extract of Corchorus olitorius L. leave.…”

“…TFC in above-ground part of I. variegata was in accordance with results for ethanolic extract of Corchorus olitorius L. leave. [46] Determination of the amount of bioactive compounds, such as phenolics, flavonoids or terpenes, is important because of their further use. For instance, the presence of four different irones compounds (cis-α-irone, trans-α-irone, β-irone and cis-γ-irone) in Iris spp.…”

This study was aimed at investigating the phytochemical composition and antioxidant capacity of rhizomes, above‐ground vegetative parts and flowers of three Iris species: Iris humilis Georgi, Iris pumila L. and Iris variegata L. UHPLC‐Orbitrap MS analysis was used for determination of phytochemical profile. Total pigments, phenolics, flavonoids, soluble sugars and starch content as well as ABTS antioxidant capacity were also determined. In total, 52 phenolics compounds were identified with 9 compounds (derivatives of iriflophenone, apigenin C‐glycosides, luteolin O‐glycoside, isoflavones derivatives of iristectorigenin, dichotomitin, nigracin and irilone) never reported before in Iris spp. Differences in phenolic composition profile, pigments, soluble sugar, starch, total phenolics and flavonoids content and total antioxidant capacity were found among Iris species and different part of plants. Significant correlation between total phenolic content and antioxidant capacity was determined. The obtained results are comparable with those obtained for medical plants. These findings could be useful for fingerprinting characterization of Iris species and estimation of possible use in pharmaceutical industries.

“…Ethanol extract of Z. lotus fruit was filtered through a 0.45 μm filter before injection into the HPLC system. LC-ESI-MS analysis was performed using a LCMS-2020 quadruple mass spectrometer (Shimadzu, Kyoto, Japan) equipped with an electrospray ionization source (ESI) and operated in negative ionization mode according to the method reported by Jdir et al [13]. Chemical standards used for the LC-ESI-MS system were HPLC grade and were purchased from Sigma Chemical Co. (St. Louis, MO, USA).…”

Jujube (Ziziphus lotus L.) fruit has multiple functional properties and represents an interesting source of bioactive compounds. The purpose of this study was to improve the functionality and the sensory properties of sponge cake enriched with Z. lotus fruit. The polyphenols and flavonoids levels in the sponge cake and its antioxidant potential increased with the addition of 0-10 g of jujube powder/100 g of wheat flour. The crumb color parameters, L* and b*, decreased with the addition of jujube powder, whereas the a* value increased. In the texture analysis, addition of jujube powder resulted in an increase of the hardness and chewiness, but the springiness was reduced. The sensory evaluation showed that supplementation of jujube powder did not manifest any undesirable organoleptic response and showed satisfactory consumer acceptability. Overall, the addition at 5% jujube powder showed the finest sensory properties of the sponge cake.

“…26,27 In the same way, ferulic acid has been shown to have moderate antimicrobial activity. 28,29 The for coumarin, this action is attributed to its lipophilic chemical structure, since the presence of hydroxyl groups and the size of the carbon chain facilitate their entry into the microbial cell. 30 One study has made it clear that routin acts in synergy with other phenolic compounds, potentiating the antimicrobial activity of phytochemicals.…”

The popular use of natural products has great benefits for the health of the human population. In this study we highlight Equisetum hyemale, belonging to the phylum Sphenophyta and the family Equisetaceae. Popularly, the stems of this plant are used for their diuretic, digestive, anti-anemic, and anti-inflammatory properties. Given this context, and the fact that the growth of antimicrobial resistance is a serious problem for global public health, this plant could be used as an alternative, to increase our therapeutic arsenal. Therefore, it is important to more clearly elucidate the complex structures present in plants, because these substances are mainly responsible for their beneficial and/or toxic effects. Thus, the objective of this study was evaluate the antimicrobial activity, cytotoxic and genotoxic potential of the phenolic compounds separately. The substances luteolin, ferulic acid and coumarin were identified at high concentrations by ultra-high performance chromatography-electrospray ionization-mass spectrometry (UPLC-ESI-MS). Antimicrobial activity was elucidated through microdilution in broth; the phenolic compounds were able to inhibit the visible growth of the standard bacterial strains at low concentrations. Cytotoxicity was evaluated by MTT and genotoxicity was analysed through cellular damage using a Comet assay; the results showed that it did not present cytoxicity or genotoxicity at the corresponding concentrations. With this, we suggest that E. hyemale may be an alternative for the treatment of infections by microorganisms that are resistant to synthetic drugs. .
