Understanding Stabilization of Oil-in-Water Emulsions with Pea Protein─Studies of Structure and Properties.

This study investigates the stability and structure of oil-in-water emulsions stabilized by pea protein. Of the wide range of emulsion compositions explored, a region of stability at a minimum of 5% w/v pea protein and 30-50% v/v oil was determined. This pea protein concentration is more than what is needed to form a layer covering the interface. X-ray scattering revealed a thick, dense protein layer at the interface as well as hydrated protein dispersed in the continuous phase. Shear-thinning behavior was observed, and the high viscosity in combination with the thick protein layer at the interface creates a good stability against creaming and coalescence. Emulsions in a pH range from acidic to neutral were studied, and the overall stability was observed to be broadly similar independently of pH. Size measurements revealed polydisperse protein particles. The emulsion droplets are also very polydisperse. Apart from understanding pea protein-stabilized emulsions in particular, insights are gained about protein stabilization in general. Knowledge of the location and the role of the different components in the pea protein material suggests that properties such as viscosity and stability can be tailored for various applications, including food and nutraceutical products.

Oxidative Stress as a Target for Non-Pharmacological Intervention in MAFLD: Could There Be a Role for EVOO?

Oxidative stress plays a central role in most chronic liver diseases and, in particular, in metabolic dysfunction-associated fatty liver disease (MAFLD), the new definition of an old condition known as non-alcoholic fatty liver disease (NAFLD). The mechanisms leading to hepatocellular fat accumulation in genetically predisposed individuals who adopt a sedentary lifestyle and consume an obesogenic diet progress through mitochondrial and endoplasmic reticulum dysfunction, which amplifies reactive oxygen species (ROS) production, lipid peroxidation, malondialdehyde (MDA) formation, and influence the release of chronic inflammation and liver damage biomarkers, such as pro-inflammatory cytokines. This close pathogenetic link has been a key stimulus in the search for therapeutic approaches targeting oxidative stress to treat steatosis, and a number of clinical trials have been conducted to date on subjects with NAFLD using drugs as well as supplements or nutraceutical products. Vitamin E, Vitamin D, and Silybin are the most studied substances, but several non-pharmacological approaches have also been explored, especially lifestyle and diet modifications. Among the dietary approaches, the Mediterranean Diet (MD) seems to be the most reliable for affecting liver steatosis, probably with the added value of the presence of extra virgin olive oil (EVOO), a healthy food with a high content of monounsaturated fatty acids, especially oleic acid, and variable concentrations of phenols (oleocanthal) and phenolic alcohols, such as hydroxytyrosol (HT) and tyrosol (Tyr). In this review, we focus on non-pharmacological interventions in MAFLD treatment that target oxidative stress and, in particular, on the role of EVOO as one of the main antioxidant components of the MD.

Assessment of in vitro antioxidant potential of Bambusa balcooa crude extracts and their safety evaluation based on biochemical alteration in C57bL/6 mice

Bamboo is an ancient therapeutic plant, having shoots and leaves with high nutritional as well as medicinal value. Owing to their indigenous therapeutic uses, the bamboo-based pharmaceutical and nutraceutical products are in great demand among the masses. However, anti-nutritional factors present in the shoots have toxic effects, which makes their processing and safety evaluation an essential step prior to consumed as food or for possible medicinal effects. Present study evaluated the phytochemicals, in vitro antioxidant potential and toxicity profile of crude extracts of Bambusa balcooa leaf and fresh as well as processed shoots. Total phenol and flavonoid content were found highest in the leaf extract (BLE) whereas among shoots highest content was in the fermented shoot extract (FMSE). Ferric ion reducing antioxidant power and 2,2-diphenyl-1-picryl-hydrazyl free radical scavenging activities of BLE and FMSE were also high, corresponding to the presence of various phytochemicals including rich flavonoid and phenol content. The safety profile of bamboo extracts was evaluated by their oral administration to C57BL/6 male mice with the dose of 200 mg/kg body weight for 10 weeks. Results revealed no significant alteration in body weight and general behaviour in all plant extract treated groups in comparison to control. There was slight decrease in the serum lactate dehydrogenase and glutamic pyruvic transaminase level of BLE and FMSE treated groups while serum protein, alkaline phosphatase, urea and blood urea nitrogen of all treatment groups remain similar to the control group. The study revealed that all the extracts of Bambusa balcooa are considered safe as no toxicity was observed, and fermented shoots and leaf extract having highest in vitro antioxidant activity need to be further analysed for their associated health benefits.

Muslim consumers’ behaviour towards halal nutraceutical products in Malaysia

Nutraceutical is defined as a food, or parts of a food, that provide medical or health benefits, including disease prevention and treatment. Although the primary source of nutraceutical products is plant-based, not all nutraceutical products can be categorized as halal. Many ingredients are involved in food processing and used as flavours, stabilizers, or colouring agents. In addition, some additives may be derived from non-halal sources, whether from pork, blood, non-slaughtered animals, genetically modified, or extracted with ethanol. Therefore, there is a need to identify the factors influencing Muslims’ consumer behaviour towards halal nutraceutical products to improve their awareness of them in Malaysia. For this reason, the present study has been developed to examine the factors that affect Muslim behaviour in purchasing halal nutraceutical products. This study employed a quantitative approach, with a total of 400 Muslim consumers in Malaysia participating and selected through multi-stage random sampling. Multiple regression analysis was used to determine whether Islamic values, religiosity, the maqasid shariah principle, and trust in government influence consumer behaviour toward halal nutraceutical products. The result indicated that all four factors significantly affect the consumers’ behaviour, where trust in the government was the most substantial predictive factor. This study was expected to improve halal awareness among Muslim consumers while encouraging the government to strengthen the Halal industry to protect the welfare of Muslim consumers in Malaysia.

Fast DLLME-GC-MS Method for Determination of Pesticides in Carmelite Drops and Evaluation of Matrix Effects in Related Medicinal Products.

The production of nutraceuticals is a growing trend, as many consumers consider them an important part of the modern active lifestyle. Others rely on the use of nutraceuticals instead of prescribing pharmaceuticals to improve their health more naturally. One of the major concerns in the nutraceutical industry is the potential presence of contaminants. Even low concentrations of contaminant residues can be harmful, so analytical methods that are sensitive at ultratrace levels are needed. Dispersive liquid-liquid microextraction method combined with fast gas chromatography and mass spectrometry was developed for the inspection of pesticide residues in Carmelite drops. The most suitable recoveries are presented when the alcohol content is fixed at 20% in Carmelite drops. The method was validated; the linearity, limits of detection/quantification, the method accuracy and precision were obtained. The complex nutraceutical matrix causes significant complications in quantitative analysis; therefore, the main target of the work was placed on studying the effects of the matrix on the correct expression of the resulting concentration of contaminants in different types of samples. An in-depth study of matrix factors was carried out, and its relationship with the content of potential interferents from the medicinal products as well as other components added during the drops' production was discussed. Related medicinal plant-derived nutraceuticals were tested, the method was applied for real-life samples, and positive findings are herein reported.

Effects of common nutraceutical supplements marketed for cancer prevention on tumor cell growth.

e22504 Background: In 2022, there were 1.9 million new cancer cases in the US. Data indicates that many patients receiving a cancer diagnosis begin taking supplements, believing that these products improve health. Unfortunately, most supplements lack sufficient clinical trial data to substantiate their use. Our team explores the anticancer effects of natural compounds in common nutraceuticals. We have confirmed that six compounds induce cancer cell death in vitro. However, at sublethal doses, they exhibit a biphasic effect and promote cancer cell growth. Additionally, we conduct a systematic review of these compounds to aggregate data from clinical trials on their effects in a cancer context. Methods: From the medical literature, common phytochemicals reported to have anticancer properties & sold in nutraceutical products were tested using established cancer cell lines, which include the breast, liver, colon, and ovary as the tissues of origin—cellular proliferation was measured by MTT assays. Half-maximal inhibitory concentration (IC50) was calculated, and in vitro assays described in the literature were modified to test low doses of the compounds over 96 hours. Chemicals identified to promote cell proliferation were used to conduct a systematic literature review in the PubMed database from all time through December 2023, using MeSH terms with the keywords "cancer" and "clinical trial" to tabulate compound effects in clinical trials. Results: 6 phytochemicals, reported to have anticancer properties, exhibited biphasic effects. High doses effectively suppressed cancer cells, while sublethal low doses (fractions of the IC50) induced the proliferation of cancer cells. These compounds & enriched extracts include Curcumin, Resveratrol, Rosemary extract, Rosmarinic acid, Hederagenin, & Kava extract. Curcumin & Resveratrol, which dominate the nutraceutical market, were specifically chosen for a systematic literature review. Despite their widespread use, relatively few formal clinical trials have been conducted in the cancer setting, and most showed negative or minimal anticancer effects in treated patients. No pro-growth tumor effects were reported in these trials. However, the follow-up periods were short, and the study sample sizes were small. Conclusions: We discovered 6 compounds & enriched extracts, widely marketed for anti-cancer properties, actually promote cancer cell growth at low doses. Curcumin & Resveratrol, which are prevalent in the U.S. supplement market, have insufficient clinical trial data to validate their efficacy and safety. Furthermore, our findings raise concerns about the typical milligram-level consumption of these compounds. Clinical trials indicate that such dosages result in sublethal blood concentrations, which our study has shown can be problematic. Given these findings, we advise against using these supplements until more comprehensive data is available.

Investigating the potential of yacon (Smallanthus sonchifolius) juice in the development of organic apple-based snacks

This study investigates the potential of yacon (Smallanthus sonchifolius) juice for the development of prebiotic-rich organic apple-based snacks. Yacon syrup, primarily composed of fructan, inulin, fructooligosaccharides (FOS), and free sugars, represents a promising nutraceutical product. Its great potential in food processing, particularly as an innovative source of prebiotics, has been demonstrated both in vitro and in vivo since it is fermented specifically by lactobacilli and bifidobacteria. Our objective was to explore the feasibility of employing vacuum impregnation process to incorporate yacon juice into organic apples, followed by hot air drying for the formulation of dried organic apple-based snacks with health-enhancing attributes. We assessed the prebiotic and physicochemical characteristics of the impregnated snacks, also considering 50 days of storage at room temperature. Vacuum impregnation and air drying produced dried apple slices impregnated with yacon juice with good quality and stability. Higher levels of fructan (16-fold difference compared to non-impregnated apples) in the apple slices increased their prebiotic potential, promoting the growth and viability of cells within simulated intestinal fluid, including strains of Bifidobacterium animalis subsp. lactis BB -12, Bifidobacterium breve DSM 20091, Bifidobacterium longum subsp. infantis DSM 20088, Lacticaseibacillus rhamnosus GG and Lacticaseibacillus rhamnosus C112, even after prolonged storage. Remarkably, the physicochemical parameters of the impregnated and dried apple slices remained nearly constant and akin to the control samples. Therefore, the combination of vacuum impregnation and air drying has the potential to be used to produce enriched prebiotic organic apple snacks, providing consumers with additional health benefits, including enhanced gut health, with its associated implications, and increased satiety. This innovation could contribute to the development of health-promoting food products with improved nutritional profiles.

Similarly for Klebsiella pneumonia maximum inhibitory zone (13mm) followed Pseudomonas auroginosa (13mm), Staphylococcus aureus (12mm), Candida albicans was moderate sensitive towards ethanolic extract (11mm) Conclusion: The ethanolic extract of Morinda coreia flower possessed high anti-inflammatory, antimicrobial activity than ethyl acetate and aqueous extracts on comparing with standards.

Mexican Coccoloba uvifera L. Leaf and Fruit Extracts: Identification of Pentacyclic Triterpenes and Volatile Profile by GC-MS.

Mexican Coccoloba uvifera fruit contains polyphenols, flavonoids, and anthocyanins, while in the leaves, lupeol, α- and β-amyrin have been previously identified by HPLC. However, the low resolution by HPLC of pentacyclic triterpenes (PTs) is a limitation. Moreover, the volatile profile of C. uvifera fruit is still unknown. Therefore, this study aimed to identify PTs in C. uvifera leaf and fruit extracts by CG-MS analysis and to determine the volatile profile of C. uvifera pulp by headspace solid-phase microextraction. The results showed trimethylsilylated compounds of standards lupeol, α- and β-amyrin, indicating that the silylation reaction was suitable. These trimethylsilylated compounds were identified in leaf and fruit extracts. The fruit volatile profile revealed the presence of 278 esters, 20 terpenes, 9 aldehydes, 5 alcohols, and 4 ketones. The fruit showed a high content of esters and terpenes. Due to their flavour properties, esters are essential for the food, cosmetics, and pharmaceutics industries. Moreover, terpenes in the fruit, such as menthone, β-elemene, junipene, and β-caryophyllene have the potential as anticancer and phytopathogen agents. The results indicated that GC-MS is an alternative to HPLC approaches for identifying PTs. Besides, identifying volatile compounds in the fruit will increase the value of this plant and expand its application. Identifying PTs and volatile compounds in Mexican C. uvifera leads to a better understanding of the potential benefits of this plant. This would increase the consumption of Mexican C. uvifera fresh or as functional ingredients in nutraceutical or pharmaceutical products.

Development of a protocol for fractionating and characterising fibres from lignocellulosic food waste

This study aims to explore an advanced protocol for characterising dietary fibre (DF) fractions to meet the growing demand for accurate and reliable data. Although current enzymatic-gravimetric approaches, e.g., AOAC and Van Soest analysis, provide information about soluble and insoluble DF quantification, they present limitations related to the lack of fractions characterisation. To overcome these limitations, the proposed protocol integrates the official AOAC 991.43 method with the sequential fibre fractionation by exploiting the different resistance of the fibre fractions to acid hydrolysis treatments (TFA and H2SO4), utilising hazelnut shells as a case-study. Each hydrolysed fraction was quantified and characterised through GC–MS analysis of monosaccharides. The data obtained for hemicellulose, cellulose, and lignin fractions were then discussed and compared with the Van Soest method. This approach yields a comprehensive procedure applicable to different food and nutraceutical products, emphasising the importance of DF characterisation for a deeper understanding of their bio-functional properties.

Harnessing the power of artificial neural networks methodology and multi-objective optimization for enhanced yield and bioactivity of plants polyphenolic compounds

The extraction of polyphenolic compounds from plants is crucial in the industrial production of functional nutraceuticals, but traditional methods often yield low and variable results. In this research, an innovative strategy for optimizing polyphenol extraction from two plants Cistus creticus L. and Ephedra alata subsp. alenda (Stapf) Trab., known for their rich composition in polyphenols and their bioactivities, using Ultrasound-Assisted Extraction in conjunction with artificial neural networks (ANNs) and multi-objective optimization is presented. ANNs were trained to model the intricate relationships among UAE parameters, including solvent concentration, temperature, and time, and the outcomes, encompassing polyphenol yield and bioactivity. Multi-objective optimization techniques were subsequently applied to identify extraction conditions that maximize both yield and bioactivity simultaneously. Results validate the accuracy of the ANNs model in predicting polyphenol yields and the significant enhancement in extraction efficiency and bioactivity achieved through multi-objective optimization. The extracts prepared in the optimal conditions have demonstrated superior antioxidant activities, compared to the non-optimized extracts, with the smallest values of IC50 of 242,378 µg/mL, and 146,736 µg/mL for the plants Ephedra alata subsp alenda (Stapf) Trab. and Cistus creticus L. respectively. This study introduces a promising approach for elevating the extraction of plant-derived polyphenols, augmenting their bioactivity with ANNs and multi-objective optimization. In light of the obtained results, it is recommended that further research explore the scalability and applicability of the presented innovative strategy in larger-scale industrial settings. Considering the demonstrated success in optimizing polyphenol extraction from Cistus creticus L. and Ephedra alata subsp. alenda (Stapf) Trab., extending the application of Ultrasound-Assisted Extraction, coupled with artificial neural networks (ANNs) and multi-objective optimization, to other plant species could offer valuable insights. Additionally, investigating the economic feasibility and environmental impact of implementing this strategy on an industrial scale would contribute to its practical viability.

A novel pH-stat fed-batch strategy to boost the production of nicotinamide mononucleotide by high cell density fermentation

Nicotinamide mononucleotide (NMN), a naturally occurring nucleotide with various biological activities, has recently attracted significant interest for its potential applications in pharmaceutical and nutraceutical products. In this study, a genetically engineered E. coli via pH-stat fed batch fermentation produced a high concentration of intracellular NMN. The production process involved pH-stat glucose feeding and continuous feeding of nicotinamide (NAM). Various cumulative NAM concentrations of 6.4, 8.4, 10.4, and 14 g/L produced NMN of 16.7, 21.2, 22.5, and 10.7 g/L, respectively. Furthermore, the highest intracellular NMN concentration of 22.5 g/L was produced with 10.4 g/L of total cumulative NAM concentration along with a productivity of 1.13 g/L/h. This is the highest intracellular NMN titer and productivity achieved through optimized fed-batch fermentation to date. This also demonstrates that a high cell density approach through pH-stat feeding offers the potential to produce high quality, substantial NMN at a reasonable cost.

Bee honey of the Pajeú hinterland, Pernambuco, Brazil: Physicochemical characterization and biological activity

The state of Pernambuco, in the northeast Brazil, is one the biggest bee honey producers in the country, especially in semiarid microregions called “Sertão", or hinterlands. Its unique biome characterized by xerophyte Caatinga vegetation presents a unique flora with many medicinal properties. One of these microregions, Sertão do Pajeú, has stood out for its growing honey production. The present work reported for the first time a characterization of this honey and evaluated its potential for the production of alternative nutraceutical products. Samples from Sertão do Pajeú and two other regions of the State were collected and subjected to analyses as recommended by the Brazilian legislation. As the most striking characteristics, honeys from this microregion showed darker colour, higher content of phenolic compounds and elevated antioxidant activity than that from other locations. The high content of 5-HMF, together with high diastase activity, indicated that it is an intrinsic property of this honey. And finally, fermented worts containing the probiotic yeast Saccharomyces boulardii were supplemented with honey and sucrose as reference. The results showed that samples stocked in the presence of honey presented high level of cell longevity over 60 days of storage under refrigeration. In addition, those cells became very tolerant to the simulation of the gastrointestinal tract. Therefore, this honey greatly increased the probiotic potential of the yeast. This shows the nutraceutical potential of honey from Sertão do Pajeú.

Characterization of Lipid Extracts from Different Colors of Peach Palm Fruits-Red, Yellow, Green, and White-Obtained through Ultrasound-Assisted Green Extraction.

This study represents a pioneering investigation and comparative analysis of lipid extracts from four different colors of peach palm (Bactris gasipaes Kunt) fruits-red, yellow, green, and white-by employing a green method based on ethanolic ultrasound-assisted extraction. This study examined the extraction yield, physico-chemical-quality attributes, chromatographic profiles (GC), color measurements, total carotenoid content, differential thermogravimetry (TG/DTA), and infrared spectroscopy (FTIR). The obtained lipid extracts displayed a high quality, considering the physico-chemical parameters of the Codex Alimentarius, and a fatty acids profile characterized by unsaturated fatty acids, notably omegas (ω-3, ω-6, and ω-9). The indices of atherogenicity (A.I.), thrombogenicity (I.T.), and hypocholesterolemic and hypercholesterolemic ratios revealed superior outcomes for the red peach palm lipid extract (approximately 0.35, 0.52, and 2.75, respectively), along with higher levels of β-carotene (748.36 µg of β-carotene per 100 g-1 of lipid extract) compared to the yellow, green, and white counterparts. Consequently, this research successfully demonstrates the efficacy of using a green extraction method in preserving the lipid's quality, which can display cardiovascular functionality and thermal stability. These findings underscore the considerable potential of peach palm lipid extract as a valuable raw material for diverse industrial applications across various sectors. The results support its utilization in the production of functional food products and nutraceuticals due to its favorable fatty acid composition, potent antioxidant properties exhibited by its high β-carotene content, and notable cardiovascular functionality indices.

Malus pumila Mill. cv Annurca apple extract might be therapeutically useful against oxidative stress and patterned hair loss.

Patterned hair loss (PHL) or androgenetic alopecia is a condition affecting about 50% of people worldwide. Several pharmacological medications have been developed over the years, but few studies have investigated their effectiveness. Therefore, new, safer and more effective strategies are required. Recent investigations showed that Annurca apple extract application could induce keratin production and promote hair growth thanks to the high amount of procyanidin B2 contained in. Hence, this study aimed to investigate the role of an Annurca apple extract in preventing PHL by testing it on human follicle dermal papilla cells (HFDPCs) for the first time. Treatment of HFDPCs with Annurca apple extract counteracted intracellular reactive oxygen species accumulation by increasing the activity of antioxidant enzymes such as superoxide dismutase 2 and catalase. Furthermore, treatment with Annurca apple extract increased β-catenin and fibroblast growth factor 2, which are involved in hair growth stimulation. These data suggest that Annurca apple extract may be a potential therapeutically useful nutraceutical product for preventing or treating hair loss by reducing oxidative stress and inducing the expression of hair growth-related factors.

Analysis of Proximate, Functional, and Mineral Composition in Processed Black Rice (<i>Oryza sativa</i> L. <i>indica</i>) Flours: A Comparative Exploration

Black rice is utilised to make successful nutraceutical food products because of its high nutrient content. This study sought to determine the proximate compositions, functional compositions, and mineral compositions of processed black rice flour based on different processing methods (Raw, Soaked, and Roasted). The analytical procedures for the processed flours were designed using the standard methodology. The proximate analysis of processed black rice flour revealed a differentiation at (p<0.01) in every parameter except the moisture content of raw and soaked flour. The functional properties of processed black rice flour range from 1.0 to 1.17 g/g for water absorption capacity, 2.21 to 2.43 g/g for oil absorption, and 1.8 to 2.2% for foaming capacity, with raw, soaking, and roasted black rice flour viscosities being 986.0 cP, 997.0 cP, and 951.0 cP, respectively. Bulk density ranged from 1.77 to 1.82 g/cm3. Compared to other processed flours, raw black rice flour greatly showed increased oil absorption and foaming capacity, whereas soaked black rice flour dramatically increased viscosity and bulk density. Raw black rice flour exhibited the highest composition of minerals (phosphorus, potassium, calcium, magnesium and iron) followed by soaked and roasted flours (p<0.01). The roasted black rice flour contained the highest levels of sodium. The investigation's findings demonstrated that raw black rice flour outperformed other processed black rice flour in terms of several proximate, functional, and mineral aspects, proving to be appropriate for the creation of a range of novel food products with positive health effects.

Secondary metabolic profiling, antioxidant potential, enzyme inhibitory activities and in silico and ADME studies: a multifunctional approach to reveal medicinal and industrial potential of Tanacetum falconeri

Tanacetum falconeri is a significant flowering plant that possesses cytotoxic, insecticidal, antibacterial, and phytotoxic properties. Its chemodiversity and bioactivities, however, have not been thoroughly investigated. In this work, several extracts from various parts of T. falconeri were assessed for their chemical profile, antioxidant activity, and potential for enzyme inhibition. The total phenolic contents of T. falconeri varied from 40.28 ± 0.47 mg GAE/g to 11.92 ± 0.22 mg GAE/g in various extracts, while flavonoid contents were found highest in TFFM (36.79 ± 0.36 mg QE/g extract) and lowest (11.08 ± 0.22 mg QE/g extract) in TFSC (chloroform extract of stem) in similar pattern as found in total phenolic contents. Highest DPPH inhibition was observed for TFFC (49.58 ± 0.11 mg TE/g extract) and TFSM (46.33 ± 0.10 mg TE/g extract), whereas, TFSM was also potentially active against (98.95 ± 0.57 mg TE/g) ABTS radical. In addition, TFSM was also most active in metal reducing assays: CUPRAC (151.76 ± 1.59 mg TE/g extract) and FRAP (101.30 ± 0.32 mg TE/g extract). In phosphomolybdenum assay, the highest activity was found for TFFE (1.71 ± 0.03 mg TE/g extract), TFSM (1.64 ± 0.035 mg TE/g extract), TFSH (1.60 ± 0.033 mg TE/g extract) and TFFH (1.58 ± 0.08 mg TE/g extract), while highest metal chelating activity was recorded for TFSH (25.93 ± 0.79 mg EDTAE/g extract), TFSE (22.90 ± 1.12 mg EDTAE/g extract) and TFSC (19.31 ± 0.50 mg EDTAE/g extract). In biological screening, all extracts had stronger inhibitory capacity against AChE while in case of BChE the chloroform extract of flower (TFFC) and stem (TFSC) showed the highest activities with inhibitory values of 2.57 ± 0.24 and 2.10 ± 0.18 respectively. Similarly, TFFC and TFSC had stronger inhibitory capacity (1.09 ± 0.015 and 1.08 ± 0.002 mmol ACAE/g extract) against α-Amylase and (0.50 ± 0.02 and 0.55 ± 0.02 mmol ACAE/g extract) α-Glucosidase. UHPLC-MS study of methanolic extract revealed the presence of 133 components including sterols, triterpenes, flavonoids, alkaloids, and coumarins. The total phenolic contents were substantially linked with all antioxidant assays in multivariate analysis. These findings were validated by docking investigations, which revealed that the selected compounds exhibited high binding free energy with the enzymes tested. Finally, it was found that T. falconeri is a viable industrial crop with potential use in the production of functional goods and nutraceuticals.
