Antioxidant Activity Of Aqueous Extracts Research Articles

Antioxidant Activity of Aqueous Extracts Obtained from By-Products of Grape, Olive, Tomato, Lemon, Red Pepper and Pomegranate.

The aim of this work was to study the antioxidant potential of aqueous extracts obtained from different by-products. The effectiveness of these extracts was compared with that of rosemary extract. Total phenol carotenoid and vitamin C contents, as well as in vitro antioxidant activity, were assessed. Phenol content was positively correlated with in vitro antioxidant activity in extracts, while carotenoids showed a less clear relationship. Vitamin C was associated with antioxidant activity in lemon and pepper pomace extracts. Extracts from olive, grape, and lemon by-products displayed the highest antioxidant activity (radical scavenging activity), this being similar to the activity of rosemary extracts. Moreover, the phenolic profile of the extracts was analyzed, revealing diverse phenolic compounds. Rosemary extracts contained the highest variety and quantity of phenolic compounds, while olive pomace extracts were rich in hydroxytyrosol and 4-hydroxybenzoic acid. Lemon and pepper extracts contained high amounts of tyrosol, and tomato extracts had abundant epicatechin. The PCA analysis distinguished extracts based on in vitro antioxidant activity, phenol, carotenoid, and vitamin C content, along with their phenolic compound profiles. This study emphasizes the capacity of aqueous extract by-products as valuable sources of antioxidants and highlights the importance of understanding their bioactive components.

Assessment of Anti-Microbial Efficacy against Oral Pathogens, Anti-Inflammatory, and Anti-oxidant Activity of Ethanolic and Aqueous Extract of Erythrina variegata (Indian Coral Tree) Leaves – An In-vitro Study

Aim: The aim of the study was to compare the anti-microbial efficacy against oral pathogens, anti-inflammatory, and antioxidant activity of ethanolic and aqueous extract of Erythrina variegata. Materials and Methods: Agar well diffusion method was used to assess the antimicrobial activity of ethanolic and aqueous extract of Erythrina variegata against Enterococcus faecalis and Candida albicans at 25µL, 50µL, and 100µL by measuring the zone of inhibition. Anti-inflammatory activity was assessed using the Bovine Serum Albumin (BSA) assay and anti –oxidant activity was assessed using the DPPH assay. Results: Enterococcus faecalis and Candida albicans were found to be less sensitive to both, aqueous and ethanolic extract of Erythrina variegate. The anti-inflammatory activity of ethanolic extract of Erythrina variegata was higher than the aqueous extract at lower concentrations. Anti-oxidant activity of aqueous extract of Erythrina variegata was higher than the ethanolic extract and standard values at all concentrations. Conclusion: Findings from this study suggest that both, aqueous and ethanolic extracts of Erythrina variegata leaves have the potential anti-inflammatory and anti-oxidant activity and can be used as an alternative to commercially available drugs. However, further research needs to be done on the antimicrobial activity against oral pathogens of the plant.

Evaluating the Phytochemical Composition and Antioxidant Activity of Leaves of Different Rose Varieties

Rose is a commercially significant floricultural crop that has been used for various industrial as well as decoration purposes. Along with the beautification of rose flowers, their leaves are enriched with different biologically active compounds having various therapeutic uses. The current study was performed on the phytochemical and antioxidant activity of aqueous extracts of rose leaves. In our study, we found there are consequential variations observed in all the parameters, viz., total chlorophyll, carotenoids, total anthocyanin, total phenol, flavonoids, and antioxidant activity, among all the varieties. Among the ten varieties, Thelma Barlow revealed the maximum phenolic content (35.19 mg/g FW), flavonoids content (15.97 mg/g FW), 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging activity of IC50 value (206.86 ± 0.49 µg/mL), and 2,2′-azinobis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) (301.62 ± 2.31 µg/mL). The variety Grand Amore presented the highest values for total chlorophyll (1.41 mg/g FW) and carotenoids (36.29 mg/g FW) content compared to other varieties. Also, a comparative correlation was studied amongst the phytochemicals such as anthocyanin content, total phenolic content, flavonoids, and antioxidant activities. Amongst the different rose varieties, Grand Amore and Thelma Barlow contain higher antioxidant potential, owing to their greater phytochemical activity. From our findings, we collectively concluded that fresh rose leaves contain potentially higher phenolic and flavonoid content, i.e., are responsible for higher antioxidant activity, which can be utilized for various pharmacological as well as food industries.

Comparative Study on Phytochemical Screening and Antioxidant Activity of Aqueous Extract from Various Parts of Bauhinia purpurea

In this study, we conducted a comparative investigation into the phytochemical screening and antioxidant activity of aqueous extracts from various parts of the Bauhinia purpurea plant, including leaf, flower, stem bark, and root. The qualitative analysis was performed to screen the phytochemical content of each extract, followed by quantitative analysis to determine the total phenolic and total flavonoid contents. Our findings revealed that different parts of the B. purpureaplant yielded distinct natural products upon extraction. Both the leaf and flower extracts contained alkaloids, flavonoids, saponins, carbohydrates, polyphenols, and phenolics. On the other hand, the aqueous extracts of the stem barks and rootparts of B. purpurea only contained alkaloids, flavonoids, and phenolics. Consistent with the phytochemical assay, the flower extract exhibited the highest total phenolic content (40.14 ± 0.65 µg/mL GAE) and the highest flavonoid content (387.57 ± 0.63 µg/mL CE) compared to the other parts. Consequently, the flower extract displayed the highest antioxidant activity (51.76 ± 0.32%) with DPPH radical assay, closely approaching the antioxidant activity of ascorbic acid (70.54 ± 0.51%), which served as the positive control. This significant finding highlights the potential of the B. purpurea flower as a potent source of antioxidant agents for future applications.

Therapeutic effects of Salvia balansae on metabolic disorders and testicular dysfunction mediated by a high-fat diet in Wistar rats

Medicinal plants offer an important therapeutic resource in treatment of male infertility. We aim to evaluate the possible therapeutic effects of Salvia balansae on metabolic disorders and testicular dysfunction resulting from a high-fat diet (HFD). Antioxidant activity of aqueous extract of S. balansae leaves was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, 2,2’-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) assay and total antioxidant capacity (TAC) assay. Antidiabetic activity was determined by α-amylase inhibition. In vivo, HFD was administered in Wistar rats for 18 weeks and aqueous extract of S. balansae for the last 6 weeks (200 mg/Kg of body weight/day). At the term of experimentation, testosterone and some plasma parameters were analyzed and removed testes were subjected to a histomorphometric study. Our results show high levels of phenolic components in aqueous extract of S. balansae and significant antioxidant and antidiabetic activity. HFD increases body weight, causes type 2 diabetes, dyslipidemia, liver failure and inflammation. Also, HFD decreases testosterone and alters testis histological structure (seminiferous tubular degeneration, impaired spermatogenesis and interstitial fibrosis). Treatment of HFD rats with extract of S. balansae normalizes body weight and plasma parameters, increases testosterone and regenerates testicular structure and function. In summary, S. balansae could reduce metabolic complications induced by HFD and serve the basis for developing a new therapy for testicular dysfunction.

Methods: The contents of total phenols and total flavonoids in the aqueous and ethanol extracts of Caulis spatholobi were determined, and the antioxidant activity was evaluated by DPPH, ABTS free radical scavenging rate and FRAP total reducing capacity. 30 C57BL/6J male mice were randomly divided into model group, bifendate group, the low-dose, medium-dose and high-dose groups of aqueous extract of Spatholobi Caulis (n = 6). The animal model of acute liver injury was established by intraperitoneal injection of CCl₄ after 7 days with corresponding drugs. The pathological changes of liver tissue were observed by H&E staining. Serum levels of interleukin-1β (IL-1β), interleukin-6 (IL-6), interleukin-10 (IL-10) and tumor necrosis factor α (TNF-α) were determined by ELISA. The indexes of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and antioxidant effects of catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) were determined. Results: Liver histomorphology observation showed that aqueous extract of Spatholobi Caulis could significantly improve liver cell injury and inflammatory cell infiltration, and significantly increased the activities of CAT, SOD and GSH-Px antioxidant enzymes in liver, decreased the contents of MDA and ALT and AST in serum, significantly down-regulated the levels of IL-1β, IL-6 and TNF-α in serum, and up-regulated the levels of IL-10 and other inflammatory factors. Conclusion: The aqueous extract of Spatholobi Caulis can improve acute liver injury induced by CCl₄ in mice through improving antioxidant and anti-inflammatory effects.

Fillet Fish Fortified with Algal Extracts of Codium tomentosum and Actinotrichia fragilis, as a Potential Antibacterial and Antioxidant Food Supplement.

With respect to the potential natural resources in the marine environment, marine macroalgae or seaweeds are recognized to have health impacts. Two marine algae that are found in the Red Sea, Codium tomentosum (Green algae) and Actinotrichia fragilis (Red algae), were collected. Antibacterial and antioxidant activities of aqueous extracts of these algae were evaluated in vitro. Polyphenols from the extracts were determined using HPLC. Fillet fish was fortified with these algal extracts in an attempt to improve its nutritional value, and sensory evaluation was performed. The antibacterial effect of C. tomentosum extract was found to be superior to that of A. fragilis extract. Total phenolic contents of C. tomentosum and A. fragilis aqueous extract were 32.28 ± 1.63 mg/g and 19.96 ± 1.28 mg/g, respectively, while total flavonoid contents were 4.54 ± 1.48 mg/g and 3.86 ± 1.02 mg/g, respectively. Extract of C. tomentosum demonstrates the highest antioxidant activity, with an IC50 value of 75.32 ± 0.07 μg/mL. The IC50 of L-ascorbic acid as a positive control was 22.71 ± 0.03 μg/mL. The IC50 values for inhibiting proliferation on normal PBMC cells were 33.7 ± 1.02 µg/mL and 51.0 ± 1.14 µg/mL for C. tomentosum and A. fragilis, respectively. The results indicated that both algal aqueous extracts were safe, with low toxicity to normal cells. Interestingly, fillet fish fortified with C. tomentosum extract demonstrated the greatest overall acceptance score. These findings highlight the potential of these seaweed species for cultivation as a sustainable and safe source of therapeutic compounds for treating human and fish diseases, as well as effective food supplements and preservatives instead of chemical ones after performing in vivo assays.

Synergistic effects of Nepeta menthoides and Melissa officinalis aqueous extracts on reserpine-induced depressive-like behaviors in mice.

Nepeta menthoides Boiss. & Buhse and Melissa officinalis are extensively used in Persian medicine for the treatment of depression. Considering the active ingredients and main phenolic compounds of these plants and possible synergistic effects, this study examined the antidepressant and antioxidant activities of aqueous extract of N. menthoides (NM) and M. officinalis (MO) in reserpinized mice alone and combination. Mice were pretreated orally for 1-week with normal saline (10ml/kg), fluoxetine (20 mg/kg), imipramine (10mg/kg), NM (50-100-200-400 mg/kg), MO (150-350-550-750 mg/kg), and combination (NM 50 with MO 150 mg/kg). The behavioral changes were evaluated using forced swim, tail suspension, and open field tests, 24 hr after reserpine injection (4mg/kg) on eighth day. The amounts of active components in the extracts and catalase (CAT) as a brain oxidative stress were measured with enzyme-linked immunosorbent assay. Data showed that this combination produced a synergistic action on behaviors and a significant increase in CAT activity. High-performance liquid chromatography results showed that rosmarinic acid contents in MO and NM were 6.42 ± 1.1 and 11.03 ± 2.16 mg/g of dried extract, respectively. Total flavonoid and phenolic contents of MO were higher than NM. The findings suggest that the present combination produces an antidepressant-like effect, which is possibly triggered by its antioxidant properties.

Comparison of The Phenolic Content and Antioxidant Activity in Peppermint Plant According to The Drying Method

Objective: Antioxidant activities of the plants were significantly affected by their drying methods. In the current study, total phenolic contents and antioxidant activity of aqueous extracts of peppermint (Mentha piperita L.) dried by two different methods, air-dried (AD) and freeze-dried (FD) were measured. The aim was to determine if there were any changes in the antioxidant activity according to the drying method. Material and Method: In order to determine the total phenolic compounds and antioxidant capacity of air-dried (AD) and freeze-dried (FD) mint, were used Folin Ciocalteu, CUPRAC, DPPH, ABTS, DMPD methods. Result and Discussion: Results were evaluated by comparing with the known antioxidant standards, such as gallic acid, trolox, ascorbic acid, and butylatedhydroxyanisole (BHA). The total phenolic contents (TPC) were calculated as 59.9 mg/g GAE for AD plant extract and 58.2 mg/g GAE for FD extract. According to the obtained results from all methods, radical scavenging activities were found to be slightly higher in AD samples than in FD samples. In conclusion, the results show that air-drying does not cause degradation in compounds that contribute to the antioxidant activity of the peppermint.

Analysis of the phytochemicals of Coriandrum sativum and Cichorium intybus aqueous extracts and their biological effects on broiler chickens

Spices and herbs can be used as feed additives and viable alternatives to antibiotics in chicken production. This study analyzed the phytochemicals, minerals, and antioxidant activity of aqueous extracts from Coriandrum sativum seeds and Cichorium intybus roots. The effects of different concentrations of C. sativum and C. intybus extracts on blood parameters, growth and carcass traits, biochemical parameters, and antioxidant activity of broiler chicks were also examined. The results showed that C. sativum aqueous extract has relatively higher contents of total flavonoids and total phenolic acids than C. intybus aqueous extract. Both extracts contain elevated mineral elements, especially iron, potassium, and sodium. Therefore, dietary supplementation of C. sativum seed and C. intybus root extracts could enhance broiler chicken growth performance, carcass characteristics, liver function, lipid profile, and antioxidant status. These extracts could be utilized as natural feed additives and growth promoters for broiler chickens.

Conclusion: This study has an innovative proposal with the trivial antioxidant activity combined with theoretical quantum-mechanical calculations that can serve to reduce costs and time and to predict the antioxidant activity of subsequent studies.

Phytochemical Profile and Antioxidant Activities of Aqueous Extract of Moringa oleifera (Lam) Collected from DR Congo and Kenya

Moringa oleifera Lam. is one of the most used plants in traditional medicine because of its high antioxidant properties. The antioxidant value, nonetheless, depends on locality where the plant is grown as well as specific parts on the plant. In this study, a phytochemical and antioxidant activity comparison of M. oleifera leaves, seeds and barks were carried out. Fresh leaves, seeds and barks were collected from 2 to 3 years old M. oleifera trees of Bukavu city of South Kivu province in DRC and Masii village of Machackos County in Kenya. A total of 300g of each dried sample powder was mixed with 700 mL of distilled water. Qualitative and quantitative assessment of alkaloids, saponins, phenols, flavonoids, glycosides, terpenoids and tannins were performed following standard methods while the antioxidant activity was assessed using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay. Results indicate that only alkaloids were absent in leaves from Kenya and DRC while phenols, flavonoids and tannins were absent in barks. Glycoside in seeds from DRC had the highest concentration (6.17%) followed by alkaloids in seeds from Kenya (5.56%). There was low concentration of terpenoids and flavonoids in all samples compared to other compounds. The highest extract yield was found in leaves from DR Congo (22.5%) and seeds from Kenya (20%). At the highest concentration (10 µg/mL), leaves from Kenya (88.29±1.12 µg/mL) and DRC (80.17±3.59 µg/mL) had the highest percentage inhibition of reactive oxygen-free radicals but lower than the reference standard (92.63±2.76 µg/mL). Leaves from Kenya (23.59 μg/mL) and DRC (28.67 μg/mL) had the highest IC50 compared to mean values of seeds and barks from the two countries. M. oleifera leaves, especially from Kenya, are recommended as a satisfactory antioxidant but can be substituted with seeds and/or barks in order to alleviate the use of leaves which are overused these days.

In vitro determination of the sun protection factor (SPF) and photochemoprotection potential of aqueous extract of banana peels (Musa sp.) against UV-B radiation

Banana (Musa sp.) fruits have been investigated by the scientific community for their healing properties due to their composition in bioactive compounds. In this study, the aqueous extract (AE) of banana peels (Musa sp., cv. Prata Anã) was chemically characterized and investigated regarding its antioxidant and photochemoprotective potential against UV-B radiation in BALB/3T3 clone A31 mouse fibroblasts. The results showed the AE as a source of phenolic compounds, mainly gallic acid. Antioxidant activity of AE was demonstrated by its ability to scavenge DPPH free radicals and to reduce ferric–tripyridyltriazine complex. A sun protection factor (SPF) of up to 36.4 was determined through the Mansur equation. The AE revealed low cytotoxicity (96 ± 12% cell viability - 100 µg/mL) to mouse fibroblasts and the determination of the photochemoprotective effect revealed preservation of collagen biosynthesis in cells exposed to UV-B (38.6 ± 7%), also contributing to the maintenance of cellular and nuclear morphologies. Thus, the AE of banana peels seems to be an interesting candidate for pharmaceutical/cosmetic formulations to combat skin’s photoaging caused by UV-B radiation.
