“…Opuntia ficus‐indica L. Miller (cactus pear, prickly pear or nopal cactus) belongs to the Cactaceae family and is native to Mexico. This plant can be found either in coastal regions or plateaus of the arid and semi‐arid regions of South and Central America, Africa and the Mediterranean region (El‐Mostafa et al, ; Mottese et al, ; Ouerghemmi et al, ). At this moment, O. ficus‐indica is cultivated in more than 30 countries of both hemispheres.…”

Opuntia ficus‐indica fruits have an important nutritional value and show several biological properties. This work studied the fruit physicochemical characteristics of two wild ecotypes (“Green” and “Orange”) and two cultivars (“Rossa” and “Gialla”) from Portugal. The results showed that the largest and heaviest fruits were those from ecotype “Orange,”, whereas the wild ecotype “Green” had fruits with firmer flesh. The fruit peels of cultivars “Rossa” and “Gialla” presented the highest fibre content. Glucose was the major carbohydrate in the fruits, particularly in the peels. Malic acid was the sole organic acid in both peels and pulps of all samples. The betacyanins’ content was higher in fruits of the “Rossa” cultivar, and the higher betaxanthins’ content was present in the peel of the cultivar “Gialla.” Peels of all samples generally had higher amounts of betalains than the pulps. The peel was a better scavenger of DPPH and ABTS free radicals than the pulp. Practical application The wastes of diverse food industries have revealed the presence of bioactive compounds with added value. The fruits of Opuntia ficus‐indica are appreciated for possessing biological attributes, nevertheless the peel generally is not used. The present work shows that the pigments (betalains) are predominantly found in the peel. Moreover, the in vitro antioxidant activity was also higher in this part of the fruit, independent on the ecotype or cultivar studied. Such results might trigger the interest for these residues from which pigments and bioactive compounds can be extracted, and, as extracts, can be used in diverse domains particularly in food and pharmaceutical industries.

“…Natural products’ ability to reduce metals is regarded as a key marker of their antioxidant properties [ 76 ]. Spectroscopically, the quantity of ferric (Fe 3+ ) complex conversion to ferrous (Fe 2+ ) form is detected by the color change of the solution based on the compound’s ability for reduction.…”

Bunchosia armeniaca (Cav.) DC (Malpighiaceae) is one of the well-known traditionally used remedies worldwide. This study aims to explore the leaves’ metabolome via Quadrupole-Time-of-Flight-Liquid-Chromatography-Mass Spectrometry and to investigate the neuroprotective effect of leaves using lipopolysaccharide (LPS) induced Alzheimer’s disease model. Mice were administered LPS (0.25 mg/kg/day; intraperitoneal) as well as methanolic extract (BME), dichloromethane (BDMF), and butanol (BBF) fractions (each 200 mg/kg/day; oral) for one week. BME and BBF improved behavioral activity on the Y maze test, decreased brain content of inflammatory markers such as nuclear factor kappa B and interleukin 1 beta, and prevented the elevation of cytochrome P450 2E1, and glial fibrillary acidic protein compared to the LPS-administered group. Histopathological examination of several brain parts confirmed the neuroprotective effect of the tested extracts. In addition, BBF exhibited higher activity in all tested in vitro antioxidant and acetylcholinesterase inhibition assays. Metabolic profiling offered tentative identification of 88 metabolites, including mainly flavonoids, phenolic acids, and coumarins. Several detected metabolites, such as quercetin, apigenin, baicalin, vitexin, and resveratrol, had previously known neuroprotective effects. The current study highlighted the possible novel potential of B. armeniaca in preventing memory impairment, possibly through its antioxidant effect and inhibition of acetylcholinesterase, inflammatory and oxidative stress mediators.

“…Regarding the flowers, a study by Chahdoura et al [ 59 ] on the flowering stage of O. microdasys demonstrated that ferulic acid and isorhamnetin derivates were the most frequent, ranging from 1.24–2.95 mg/g and 4.68–23.04 mg/g, respectively, while Ammar et al [ 65 ] found a higher content in quinic acid and quercetin derivates, with 1.32 and 8.50 mg/g, respectively, for O. ficus-indica flowers. Moreover, Ouerghemmi et al [ 54 ] reported that ferulic acid and quercetin were in higher amounts when compared to other phenolic compounds in O. ficus-indica flowers. It seems evident, based on the available studies, that besides the abiotic factors, the species-specific ones have a significant role in phenolics’ concentration and distribution throughout the different plant tissues.…”

Phenolic Compounds’ Occurrence in Opuntia Species and Their Role in the Inflammatory Process: A Review

et al. 2022

View full text Add to dashboard Cite

Within the Cactaceae family, Opuntia comprises the most widespread species, with a recognized importance in human life, including feeding, domestic use as home natural barriers, and as a traditional remedy for diverse diseases and conditions such asthma, edema, and burns. Indeed, scientific reports have stated that these health benefits may be due to various active compounds, particularly polyphenols, which are ubiquitously found in plants and have proven their pharmacological efficiency by displaying antimicrobial, anti-cancer, and anti-inflammatory activities, among others. Opuntia species contain different classes of phenolic compounds that are recognized for their anti-inflammatory potential. Among them, quercetin, isorhamnetin, and kaempferol derivates were reported to greatly contribute to modulate cells’ infiltration and secretion of soluble inflammatory mediators, with key implications in the inflammatory process. In this review, we make a summary of the different classes of phenolic compounds reported in Opuntia species so far and explore their implications in the inflammatory process, reported by in vitro and in vivo bioassays, supporting the use of cactus in folk medicine and valorizing them from the socio-economic point of view.
