Capparis spinosa L.: A Plant with High Potential for Development of Functional Foods and Nutraceuticals/Pharmaceuticals

Postharvest UV-B and UV-C treatments combined with fermentation enhance the quality characteristics of Capparis spinosa L. fruit, improving total phenols, flavonoids, anthocyanins, phenolic acids, and antioxidant activity

The application of UV-B and UV-C radiation may enhance the post-harvest quality of crops by delaying the ripening or aging of fruits, preventing declines in firmness, maintaining stable pH levels, increasing certain antioxidants such as phenolic compounds, and minimizing spoilage. Additionally, the fermentation process, a traditional method of food preservation, not only extends the shelf life of foods but also promotes the formation of natural bioactive components and enhances organoleptic properties. This study aimed to investigate the effects of UV radiation and fermentation on caper (Capparis spinosa L.) berries through a factorial experiment designed as a completely randomized design with three replications. Four levels of UV radiation: control (no radiation), UV-B radiation, UV-C radiation, and UV-B + C radiation were applied. Following the UV treatment, fermentation was initiated, with four sampling stages conducted throughout the fermentation period (fresh fruits or control, and days 15, 30, and 45 during fermentation). The results indicated significant increases in total phenol content, flavonoids, anthocyanins, antioxidant activity, and the activity of the enzyme phenylalanine ammonia-lyase (PAL) in caper berries treated with UV-B and, particularly, UV-C radiation. The levels of most phenolic compounds, including caffeic acid, gallic acid, p-hydroxybenzoic acid, cinnamic acid, rosmarinic acid, p-coumaric acid, m-coumaric acid, ferulic acid, protocatechuic acid, and vanillic acid, significantly increased under UV-C, UV-B, and UV-B + C exposure compared with the control (no UV application). Regardless of the UV treatment, fermentation significantly elevated the levels of phenolic acids such as caffeic acid, gallic acid, ferulic acid, m-coumaric acid, p-hydroxybenzoic acid, protocatechuic acid, rosmarinic acid, and vanillic acid, resulting in concentrations that were considerably higher in fermented fruits 45 days post-fermentation than in fresh fruits. Additionally, the total phenol and flavonoid contents in UV-treated fruits on day 45 of fermentation exceeded those in fresh fruits. In contrast, samples not exposed to UV radiation showed no significant changes in these attributes during fermentation. Overall, irrespective of the UV treatment, fermentation of the fruits up to day 30 led to increases in antioxidant activity, PAL activity, anthocyanin content, cinnamic acid, and p-coumaric acid in caper berries. However, the level of cinnamic acid decreased on day 45 compared with day 30. Ultimately, caper fruit treated with UV irradiation and fermented exhibited enhanced health potential due to their unique characteristics.

GC-MS analysis and nutra-pharmaceutical potential of Mentha piperita essential oil extracted by supercritical fluid extraction and hydro-distillation

This study reports the comparative evaluation of yield, physico-chemical composition and biological attributes (antioxidant activity, antimicrobial activity, biofilm inhibition and hemolytic activity) of peppermint (Mentha piperita L.) essential oil (EO) obtained by hydro-distillation (HD) and supercritical fluid (CO2) extraction (SCFE) methods. The yield (%) of EO obtained by HD (0.20 %) was significantly (p < 0.05) higher than that of SCFE (0.13 %) while the variation in the physical parameters like solubility, color, density (at 25 °C) and refractive index (at 25 °C) was not significant between the tested oils. The data of chemical compositional analysis revealed that menthol was the key component in the EO obtained by HD (52.85 %) and SCFE (45.51 %), followed by menthone [HD (25.93 %) and SCFE (27.3 %)] and eucalyptol [HD (8.59 %); SCFE (8.92 %)]. The EO extracted with supercritical fluid (SCFE-EO) exhibited superior (p < 0.05) DPPH free radical inhibition potential (52 %) with an IC50 value of 15.65 μg/mL and reducing power compared to that of HD-EO. The highest antimicrobial activity was exhibited by SCFE-EO against Pasturella multocida with an inhibition zone of 18.00 mm (MIC value of 86 μg/mL). The results of biofilm inhibition and hemolytic activity revealed that the SCFE method was superior to recover high quality EO in comparison to the HD method. The peppermint EO obtained by SCFE, owing to potent bioactive components, can be a potential candidate to develop nutra-pharmaceuticals.

Nanoliposomal Encapsulation of Capparis spinosa Extract and Its Application in Jelly Formulation

This research aimed to encapsulate the Capparis spinosa fruit extract to increase its stability for incorporation into food products such as jelly or jelly powder. After extraction, the nanoliposomes containing the extract were prepared in ratios of 60-0, 50-10, 40-20, and 30-30 lecithin-to-cholesterol. The effects of lecithin-to-cholesterol concentrations on the related parameters were then evaluated. The results showed that the average particle size was in the range of 95.05 to 164.25 nm, and with an increasing cholesterol concentration, the particle size of the nanoliposomes increased. The addition of cholesterol increased the zeta potential from -60.40 to -68.55 millivolt. Furthermore, cholesterol led to an increase in encapsulation efficiency, and even improved the stability of phenolic compounds loaded in nanoliposomes during storage time. Fourier transform infrared (FTIR) spectroscopy confirmed the successful loading of the extract. Field emission scanning electron microscopy (FE-SEM) analysis revealed nano-sized spherical and almost-elliptical liposomes. For jelly powders, the water solubility index ranged from 39.5 to 43.7% (p > 0.05), and the hygroscopicity values ranged between 1.22 and 9.36 g/100 g (p < 0.05). In conclusion, nanoencapsulated Capparis spinosa extract displayed improved stability and can be used in jelly preparation without any challenge or unfavorable perception.

Network pharmacology and multitarget analysis of Nigella sativa in the management of diabetes and obesity: a computational study

Obesity and diabetes are commonly associated with one another and represent a significant global health issue, with a recent surge in disease incidence. Nigella sativa, also known as black cumin, is believed to possess several health benefits, including anti-diabetic, anticancer, antioxidant, antimicrobial, and anti-obesity properties. In this study, we aimed to identify the active compounds derived from N. sativa, which can potentially inhibit key protein targets and signaling pathways associated with diabesity treatment. We employed an exhaustive in silico search, which led to the identification of 22 potential compounds. Out of these, only five hits were found to be non-toxic, including Arabic and ascorbic acids, dihydrocodeine, catechin, and kaempferol. Our analysis revealed that these hits were associated with genes such as AKT1, IL6, SRC, and EGFR. Finally, we conducted molecular docking and molecular dynamics simulations, which identified kaempferol as the best binder for AKT1 in comparison to the reference molecule. Overall, our in silico integrated pipeline provides a useful approach to identify non-toxic phytocompounds as promising drug candidates to treat diabetes and obesity.Communicated by Ramaswamy H.

A bilayer biocompatible polycaprolactone/zinc oxide/Capparis spinosa L. ethyl acetate extract/polylactic acid nanofibrous composite scaffold for novel wound dressing applications

Capparis spinosa L. (CSL) is used in traditional medicinal purposes for wound dressing because it contains natural phenolic and flavonoid active compounds. In the current study, a bilayer of biocompatible and mechanically stable nanofiber scaffolds with polycaprolactone (PCL)/zinc oxide and Capparis spinosa L. ethyl acetate extract (CSLE)/polylactic acid (PLA) layers was successfully prepared by an electrostatic spinning technique. Microstructural observations carried out by scanning electron microscopy (SEM) have shown that the nanofibers with a smooth surface are continuous and bead-free, and that the size distribution is uniform, with an average diameter of 314.15 nm. The results of careful observation further suggested that polymers in the nanofibers have excellent compatibility with drugs. The results of Fourier transform infrared (FTIR) spectroscopy suggested that CSLE and zinc oxide nanoparticles (ZnO) were successfully loaded in the nanofiber membranes. Water contact angle measurements revealed that the bilayer nanofiber membranes exhibited satisfactory wettability (outside layer, 130°; inner layer, 72.4°). Tensile testing showed that the bilayer PCL/ZnO-CSLE/PLA nanofibers remained unbroken until reaching 10.69 MPa, which is much higher than the tensile strengths of the individual layers or the individual components. Moreover, agar disk diffusion assessment confirmed that the bilayer nanofiber membranes obviously hindered bacterial growth. Cytotoxicity studies showed that the bilayer nanofiber membranes effectively accelerated cell proliferation. The investigated PCL/ZnO-CSLE/PLA bilayer nanofibers have potential for use as membranes for wound dressing applications.

Capparis spinosa inhibits Leishmania major growth through nitric oxide production in vitro and arginase inhibition in silico

Cutaneous leishmaniasis is an infectious disease, considered as a major public health problem in different regions of the world. The current treatments are limited due to their toxicity and treatment failures, which have increased the search for new substances of natural origin to control this infection. Capparis spinosa is an important medicinal plant, rich in biochemical compounds with a broad range of activities including antimicrobial effects. Nevertheless, more investigations are still needed to determine its effect on Leishmania parasites. This study aimed to evaluate the effect of C. spinosa' extracts on Leishmania major promastigotes and amastigotes growth as well as on L-arginine metabolic pathways, especially the production of leishmanicidal molecules such as nitric oxide. Our results showed that C. spinosa' methanolic and aqueous extracts contained polyphenols and flavonoids at different concentrations. The methanolic extract of C. spinosa, compared to the aqueous extract, showed significantly higher amounts of total polyphenols (21.23 ± 1.08) mg GAE/g of dw (P < 0.05), as well as a higher antioxidant activity evaluated respectively by Reducing Power and DPPH (EC₅₀: 0.31 ± 0.02 and 7.69 ± 1.28) mg/ml. Both extracts significantly inhibited L. major promastigotes and intra-macrophagic amastigotes growth in vitro in a dose-dependent manner (P < 0.001) and induced NO production not only in Leishmania-infected macrophages but also in uninfected macrophages, without showing any cytotoxicity in vitro. Furthermore, in silico docking studies showed that C. spinosa compounds identified by RP-HPLC exhibited inhibitory activity against the arginase enzyme. The leishmanicidal effect of C. spinosa may be due to its phenolic content and its mechanism of action may be mediated by an increase in NO production and by the inhibition of arginase enzyme in silico. These findings support the hypothesis that C. spinosa might be a valuable source of new biomolecules for leishmaniasis treatment.

The Capparis spinosa var. herbacea genome provides the first genomic instrument for a diversity and evolution study of the Capparaceae family

BACKGROUND

The caper bush Capparis spinosa L., one of the most economically important species of Capparaceae, is a xerophytic shrub that is well adapted to drought and harsh environments. However, genetic studies on this species are limited because of the lack of its reference genome.

FINDINGS

We sequenced and assembled the Capparis spinosa var. herbacea (Willd.) genome using data obtained from the combination of PacBio circular consensus sequencing and high-throughput chromosome conformation capture. The final genome assembly was approximately 274.53 Mb (contig N50 length of 9.36 Mb, scaffold N50 of 15.15 Mb), 99.23% of which was assigned to 21 chromosomes. In the whole-genome sequence, tandem repeats accounted for 19.28%, and transposable element sequences accounted for 43.98%. The proportion of tandem repeats in the C. spinosa var. herbacea genome was much higher than the average of 8.55% in plant genomes. A total of 21,577 protein-coding genes were predicted, with 98.82% being functionally annotated. The result of species divergence times showed that C. spinosa var. herbacea and Tarenaya hassleriana separated from a common ancestor 43.31 million years ago.

CONCLUSIONS

This study reported a high-quality reference genome assembly and genome features for the Capparaceae family. The assembled C. spinosa var. herbacea genome might provide a system for studying the diversity, speciation, and evolution of this family and serve as an important resource for understanding the mechanism of drought and high-temperature resistance.

The article provides an analysis of the cenopopulation and tissues element composition of the medicinal caper plant Capparis spinosa L. distributed on Calcisols formed on eroded alluvial-proluvial gravel textured rocks in the south of the Fergana Valley (Uzbekistan, Central Asia). The predominance of immature plants in the cenopopulation was detected in the Arsif hills massive, and quantitative indicators of micronutrients in the vegetative and generative organs of C. spinosa L. were determined. The study of biomorphological characteristics of the plant during the growing season (April-October) was carried out in the identified 10 observational experimental field populations. The cenopopulation dynamics and plant development patterns of Capparis spinosa L. were characterized for environmental conditions of south Uzbekistan for the first time. Soil, plant element analysis was performed by neutron-activation method. In this case, the samples were irradiated in a nuclear reactor with a neutron flux of 5 × 10¹³ neutrons/cm² s, and their quantities were determined in accordance with the half-life of chemical elements. It has also been compared with research materials conducted by world scientists on the importance and pharmacological properties of botanicals in medicine and the food industry, as well as their botanical characteristics. The plant can serve to conserve soil resources, as it prevents water and wind erosion of dense clay soils in the dry subtropical climate of Central Fergana and could be considered an effective agent of destroyed soils remediation. The development of this plant will contribute to the diversification of agriculture in Uzbekistan (Central Asia) and the development of the food industry and pharmacology.

Effect of nano extracts of olea europaea leaves, ficus carica and liraglutide in lipidemic liver of type 2 diabetic rat model

The study aimed to evaluate the impact of Ficus carica mixture and Olea europaea leaf nano extracts, and liraglutide, on liver tissue and serum lipids in type 2 diabetic male albino rat model. Forty rats were divided equally into 4 groups were used. Group 1 was the non-diabetic control group. The animals in Groups 2–4 was injected intraperitoneally with a single dose of 60 mg/kg b.w. Streptozotocin to induce a diabetic rat model. Group 2 served as a positive control for diabetes. 0.02 mg/kg b.w./day of Liraglutide gave to groups 3 and 4 and 4.8 ng/ml × 10⁵ b.w./day of a mixture of the nano extracts, respectively. Eight weeks after treatment, the animals were sacrificed. Blood was collected for glucose analysis and serum low-density lipoprotein, high-density lipoprotein, total cholesterol, and triglycerides analysis, and the livers processed for histopathological examination. The elevated lipid profiles and blood glucose levels in diabetic group (Group 2) were significantly reduced (p < 0.001) following the administration of liraglutide and nano extracts in Groups 3 and 4. Progressive fatty acid changes were found in the liver sections, indicated by the deposition of various sizes of lipid droplets in most liver lobules, along with patchy hepatocyte necrosis. These pathological changes were ameliorated in the liraglutide- and nano-extract-treated rats. Treatment with the nano extracts resulted in significant power assays associated with recovery of hepatic histology and functional alterations, compared to liraglutide treatment.

In vitro evaluation of hydroalcoholic extracts of Capparis Spinosa L., Ricinus communis, and Solanum luteum on Leishmania major (MRHO/IR/75/ER) promastigotes

Background: Plant extracts or compounds derived from plants are a valuable source for finding new anti-leishmaniasis drugs. Objective: In this study, Capparis spinosa L., Ricinus communis, and Solanum luteum were used as lethal agents for the promastigotes of Leishmania major parasites in the culture medium. Methods: Diluted extracts of 12.5, 100, and 500 mg/mL were prepared from medicinal plant dried extracts. Glucantime at a concentration of 500 mg/mL was used as a positive control. Results: For all three extracts, concentrations of 100 and 500 mg/mL could kill promastigotes at higher rates and speeds compared to other concentrations. The high concentrations of extracts (500 mg/mL) presented similar effects. According to the findings, hydroalcoholic extract of C. Spinosa L. presented considerably lower antiparasitic effects, and S. luteum and R. communis extracts were could kill most of the parasitic promastigotes at higher doses. The ANOVA test did not show any significant viability percentage difference of Leishmania extracts between different extract types. Conclusions: In this study, the lethal effects of R. communis and S. luteum hydroalcoholic extracts on L. major promastigotes were found to be stronger than the C. Spinosa L. extract.

Can the Caper (Capparis spinosa L.) Still Be Considered a Difficult-to-Propagate Crop?

As a perennial xerophytic shrub, characterized by plesiomorphic features, the caper (Capparis spinosa L.) is naturally spread throughout the Mediterranean basin and occupies an important ecological role, as well as an economic one, in traditional and specialized systems for commercial production. This species, in spite of its wide diffusion, is currently considered at risk of genetic erosion, mainly due to overgrazing and overharvesting for domestic uses and for trade. This situation is made more serious because of the lack of efficient propagation techniques, determining the caper as a “difficult-to-propagate species”. In this review, we report the main available sexual and vegetative propagation techniques with the aim of assessing whether, and to what extent, this criticality is still true for caper as a horticultural crop. In terms of seed propagation, germination rates have generally been considered quite low or unsatisfactory, and are also affected by hybridization phenomena that are likely to occur among both the wild and cultivated forms. The seeds show a physiological dormancy that can be lowered by adopting hormonal treatments, but in situ germination remains a critical phase. Vegetative propagation appears quite effective, mostly as related to in vitro techniques that allow caper cultivation that is no longer affected by propagation for an economic dissemination of the species in more intensive orchards. The research needs for Caper spinosa L. as a horticultural crop, especially in the field of genetic improvement and breeding, are also underlined.

In vitro effects of Capparis spinosa L. extract on human sperm function, DNA fragmentation, and oxidative stress

ETHNOPHARMACOLOGICAL RELEVANCE

Oxidative stress is one of the underlying causes of male infertility. Medicinal plants have many benefits for infertility treatment in men.

AIM OF THE STUDY

In the present study, we evaluated in vitro effects of Capparis spinosa leaf extract on human sperm function, DNA fragmentation, and oxidative stress.

MATERIALS AND METHODS

We conducted this study on the hydroalcoholic extract of C. spinosa. Polyphenol compounds and antioxidant effects of the leaf and fruit extract were determined by HPLC and DPPH method, respectively. Flavones and flavonols, total flavonoid, total phenolic content, tannin, and the total carbohydrate content were determined calorimetrically. Semen samples from 50 healthy men (20-45 years) were divided into control and experimental (15, 30, and 45 ppm of C. spinosa leaf extract) groups. Motility, viability, lipid peroxidation, and DNA fragmentation were evaluated 24 h after incubation.

RESULTS

The antioxidant effect of leaf extract was six times greater than fruit. Progressive and total motility of caper-treated groups (30 and 45 ppm) were crucially higher than the control group. Viability in all treatments was significantly higher than the control group. There was no significant difference in lipid peroxidation. DNA fragmentation in the caper-treated group (45 ppm) was significantly lower than the control group.

CONCLUSIONS

Our results suggest the potential positive in vitro effect of C. spinosa leaf extract on human sperm function. The use of C. spinosa leaf extract or its active metabolites in the sperm culture medium may be beneficial for maintaining motility, vitality, and sperm DNA. Since these effects were observed at very low concentrations of caper, other non-antioxidant mechanisms must be considered.
