GC/MS evaluation of the composition of the Aloe vera gel and extract

This study aimed to investigate the potential use of Aloe vera (AV) as a food additive given its critical importance in food safety and health. Specifically, the natural antimicrobial and antioxidant properties of AV were examined to prevent food spoilage and extend its shelf life. This study was conducted using commercially available aloe vera gel (AVG) and aloe vera extract (AVE). These samples were tested using gas chromatography–mass spectrometry (GC–MS). The analysis involves identifying and quantifying the components using natural helium gas. The antimicrobial and antifungal effects of these components were evaluated and compared with those reported in the literature. GC–MS analysis revealed that the Aloe vera gel and extract contained various volatile components, including phenolic compounds, anthraquinone glycosides, and different esters. According to GC–MS results of the two different forms of AV, the main volatile compounds of the gel form were levoglucosan, tridecanoic acid, decanoic acid methyl ester, octadecanoic acid methyl ester, octadecanoic acid, nonadeca-1.18-diyn-4.16-diol and squalene, whereas the extract form contained volatile compounds with antifungal activity such as tridecanoic acid, octadecanoic acid methyl ester, octadecanoic acid, nonanoic acid and eicosyl acetate. Both samples exhibited antimicrobial and antifungal activities, especially against pathogens such as Staphylococcus aureus, Candida albicans, Aspergillus niger, and Escherichia coli. This study demonstrated the potential of Aloe vera gel and extract as a natural preservative for use in food because of its constituent components. This study highlights the potential use of Aloe vera as a natural additive in the food industry. Due to its antimicrobial and antifungal properties, Aloe vera offers an organic alternative to chemical additives. Aloe vera is effective at preventing food spoilage and extending shelf life, making it a suitable option for meeting consumer demand for organic and natural products.

Efficient green combustion production of pure nickel oxide (NiO) and silver-doped NiO nanoparticles using Aloe Vera gel extract: Its supercapacitors applications

This study employs the synthesis of pure NiO and Ag-doped NiO with varying concentrations (1, 3, 5, 7 and 9 mol%) of Ag2O nanoparticles by solution combustion method. The Structural and morphology of nanomaterials were elucidated by analytical spectroscopic methods. XRD revealed alterations in physical properties, such as crystallite size and lattice parameters, of NiO nanoparticles due to the presence of Ag2O. UV-Vis spectroscopy demonstrated a reduction in the bandgap from 3.41 eV (pure NiO) to 3.21 eV for 1, 3, 5, 7 and 9 mol% Ag2O-doped NiONPs. To assess their viability as active electrode materials in supercapacitors, the synthesized samples were subjected to analysis in a 0.1 M HCl electrolyte. Electrochemical studies done through various tests, including Electrochemical-Impedance, Cyclic-Voltammetry and Galvanic Charge-Discharge. Remarkably, the 5 mol% Ag2O-doped NiO in a 3-electrode system exhibited a notable capacitance value of 248 Fg−1 at a scan rate of 5 Ag−1. Additionally, it demonstrated robust cycling stability, maintaining over 90% of the original capacitance after 2000 cycles in GCD studies. The potential chemical interaction between nanoscale Ag2O and NiO could be responsible for the enhanced capacitance. These findings offer valuable insights for researchers exploring the development of novel electrode materials for energy-storage devices.

Impact of fuel and reducing agent on photoluminescence and supercapacitor applications of rhombohedral silver gallium oxide (AgGaO2) nanoparticles

To investigate the benefits of a green-mediated route compared to the chemical route in synthesising AgGaO2 NPs, both methods were employed, and a comprehensive analysis of their characterization, photoluminescence, and electrochemical properties was conducted. In this study, silver gallium oxide (AgGaO2) nanoparticles (NPs) were synthesised using two distinct methods: a chemical route employing urea as a fuel (AgGaO2U) and a green-mediated route using Aloevera gel extract as a reducing agent (AgGaO2A), followed by calcination at 600oC for 3 h. The XRD analysis confirmed the formation of a trigonal structure in both AgGaO2U and AgGaO2A NPs. Rietveld analysis provided insight into lattice parameters, space groups, and packing diagrams. AgGaO2A exhibited smaller NPs compared to AgGaO2U. The direct energy band gap, determined using Wood and Tauc’s relation, was 3.2 eV for AgGaO2U and 3.04 eV for AgGaO2A. AgGaO2A displayed a smaller crystallite size and a higher energy band gap. Photoluminescence spectra, excited at 224 nm, revealed emissions in the violet, blue, green, and red regions, with the highest intensity observed in the blue region. This was further confirmed by CIE coordinates, which fell within the blue region, with AgGaO2A exhibiting higher intensity than AgGaO2U. Electrochemical studies demonstrated supercapacitance values ranging from 24.8 to 69.8 F/g at different scan rates. While the choice of fuel or reducing agent influenced photoluminescence intensity, electrochemical studies showed consistent behaviour in both synthesised samples, suggesting their potential applications in displays and supercapacitors.

Dy3+ doped Silver Gallium Oxide (AgGaO2) nanoparticles (NPs) (AGO:Dy3+) are effectively synthesized via a green mediated route using Aloe vera gel extract as a reducing agent, followed by calcination at 600 °C for 3 h. Powder X-ray diffraction (PXRD), Fourier transformation infrared (FTIR), scanning electron microscopy (SEM), energy dispersive X-ray (EDX), photoluminescence (PL), and electrochemical studies were employed to confirm the synthesis, structural, luminescence, and supercapacitor properties of the NPs. The diffraction peaks of the synthesized samples possess a trigonal structure within a rhombohedral system. The surface morphology consists of a few irregular, a few hexagonal, and a few rice grain-structured NPs. The changes in the agglomeration were observed with variations in the dopant concentration. The direct energy band gap increases from 3.11 to 3.13 eV with an increase in the dopant concentration. Under 276 nm excitation, the PL spectra of AGO:Dy3+ nanophosphors reveal robust emission peaks attributed to 4F9/2→6F15/2 (480 nm) and 4F9/2→6F13/2 (565 nm). The confirmed critical distance signifies that energy transfer occurs through a multipolar interaction mechanism. The CIE chromaticity diagram illustrates the emission of yellowish green light from the phosphors. These investigations indicate the potential applications of AGO:Dy3+ nanocrystals in a light-emitting diode as a nanophosphor material. Nanocrystals in light-emitting diodes as a nanophosphor material. Thorough electrochemical investigations, encompassing cyclic voltammetry, were conducted to decipher redox reactions, electrode kinetics, and electrochemical behavior. The precise elucidation of ion transport kinetics was achieved through Electrochemical Impedance Spectroscopy (EIS), while the determination of supercapacitance values was accomplished via Galvanostatic Charge-Discharge (GCD) analysis. The supercapacitance values exhibited a remarkable range from 76.177 to 111.53 F/g, underscoring their sensitivity to dopant concentration. Consequently, the material synthesized in this groundbreaking study exhibits substantial promise for diverse applications, spanning from energy storage materials to the dynamic landscape of display technology.

Effect of edible coating containing Aloe vera extracts on the oxidative stability and quality parameters of cooked ground chicken meat

This study investigated the impact of incorporating Aloe vera gel (AVG) and Aloe vera leaf skin (AVLS) extracts into edible coating (EC) on retarding lipid oxidation and enhancing the quality characteristics of cooked ground chicken meat during 14 days of storage at 4 °C. The results indicated that both AVG and AVLS extracts had a similar amount of total phenolic contents. EC application resulted in a decrease in pH values, and an increase in aw values. The addition of 2% AVG or AVLS extracts into EC formulation also decreased TBARS and ORP values. Although textural properties were not affected by EC application containing AVG or AVLS extracts, this application retarded L*, a*, and b* color values. The results indicated that Aloe vera extracts may be incorporated into EC by processors to improve lipid oxidation inhibition and maintain the quality characteristics of poultry meat products during refrigerated storage.

Enhancing effects of Aloe vera gel extracts on the humoral and cellular immune response and growth performance in broiler chickens.

The experiment evaluated how Aloe vera gel (AVG) extract supplementation affected immune responses and physiological performances in broiler chickens. 90-day-old Cobb 500 broiler chicks were reared for 38 days without the addition of antibiotics, either through feed or water. At 10 days, chicks were allocated into three groups: A, B, and C (n = 30). Group A served as non-supplemented control. Groups B and C were administered aqueous extracts of AVG at 1.0% and 2.0%, respectively, with drinking water. The supplementation of AVG potentiated the chicken immune response to Newcastle disease-vaccinated birds and sheep red blood cell-treated birds, which detected the highest antibody titers against Newcastle disease virus and sRBC. The cellular immune response evaluated through a cutaneous basophilic hypersensitivity test using phytohemagglutinin-P demonstrated a significant increase in skin thickness in AVG-supplemented birds. The relative sizes of lymphoid organs (bursa, spleen, and thymus) were significantly enhanced (p < 0.05) among the groups. Broilers given AVG-1 and AVG-2 exhibited significantly greater (p < 0.01) live body weight, dressing percentages, and serum protein and serum albumin levels. The supplemented groups experienced a significant reduction in total serum cholesterol, triglycerides, and low-density lipoprotein-cholesterol values, while the levels of high-density lipoprotein-cholesterol remained unchanged. The dietary aqueous extracts of AVG are effective in enhancing innate and specific immunity. This work strengthens the perspective of the use of AVG as an immune stimulant to facilitate recovery from immune suppression states, enhance innate and specific immunity, and improve broiler growth performance.

Electrochemical studies of nickel oxide nanoparticles via solution combustion method using green and chemical fuels

The efficient manufacture of nickel oxide nanoparticles (NiO NPs) using a novel solution combustion method that makes use of chemical (glucose) and green (Aloe vera gel extract) fuels is reported in this work. As revealed by electron microscopy, the synthesized samples were spongy, spherical, agglomerated, and porous; in contrast, the face-centered cubic crystal structure (FCC) phase for NiO NPs was corroborated by PXRD. The energy band gaps of NiO NPs are 4.09 and 4.21 eV. Using an eco-friendly NiO electrode, cyclic voltammetry investigations demonstrated good reversibility (a reduced value of EO-ER). Its great conductivity was confirmed by electrochemical impedance tests, which also showed a low charge-transfer resistance. Using NiO NPs, stable electrode materials for application in supercapacitors can be readily created. In comparison to chemically synthesized NiO green generated NiO in a 3-electrode setup demonstrated a capacitance of 156 Fg−1 and 183 Fg−1 at a scan rate of 5 Ag−1, respectively, according to the GCD investigation. It also had good cycling stability, retaining more than 85% of its original capacitance after 2000 cycles. The results suggest that green produced NiO could be a cheap and practical material for use in supercapacitor applications in the future.

Efficacy of a novel combination of aloe vera gel and pineapple extracts in improving post-extraction pain and healing: A Randomized Controlled Trial.

Absorbable gelatin sponges are able to reduce the incidence of post-extraction complications when soaked with antimicrobial agents. However, the drawbacks associated with the injudicious use of antibiotics warrant the need to explore alternatives to the existing drugs. Aim: The present study aimed to evaluate the efficacy of an absorbable gelatin sponge soaked in a combination of aloe vera and pineapple extracts in reducing post-operative pain and improving the healing rate following dental extractions. Patients aged 18 to 60 years undergoing a single dental extraction of a posterior tooth were provided with either plain absorbable gelatin sponge (control group) or absorbable gelatin sponge soaked in freshly prepared solution of aloe vera gel and pineapple extracts. The pain levels were measured after one, three, seven, and fourteen days post-extraction. The socket healing status was evaluated by Landry Turnbull and Howley Index after one and two weeks post-extraction respectively. The mean pain was significantly less (p<0.05) for patients in the experimental group on the 1st, 3rd, and 7th postoperative days as compared to the patients in the control group. No significant differences (p>0.05) were observed in the healing status between the two groups at any time interval. The present study found the combination of aloe vera gel and pineapple extracts to be effective in reducing post-operative pain following dental extractions. While the improvement in the healing rate failed to reach statistical significance in the present study, generally less inflammation was observed in sockets treated with absorbable gelatin sponge soaked in the a combination of aloe vera and pineapple extracts. Key words:Post-extraction pain, Socket healing, Aloe Vera, Bromelain.

The effect of maltodextrin and drying temperature on the characteristics of Aloe-bignay instant drink

The formulation of functional drinks based on aloe vera gel and bignay fruit extract (Aloe-bignay) has the potential to be developed. Aloe vera gel contains glucomannan and fiber which are also good for health. Bignay also provides health effects because it contains a lot of anthocyanins and has the ability as an antioxidant. The weakness of Aloe-bignay drink products is the occurrence of precipitation and discoloration during storage. One of the steps that can be taken to optimize the formulation and extend the shelf life is to add a filler of maltodextrin into Aloe-bignay instant drink. The purpose of this study was to determine the effect of maltodextrin concentration and temperature of drying on the characteristics of the Aloe-bignay instant drink. The research design used a completely randomized 2-factor design consisting of factor 1 was maltodextrin concentration (10%, 20%, and 30%) and factor 2 was the drying temperature (30°C, 40°C, and 50°C). The aloe-bignay instant drink was determined by its characteristics, namely color (ΔE), moisture content, water-soluble index, vitamin C, antioxidant activity, and acidity. The results showed that the concentration of maltodextrin affected the color (ΔE) and moisture content, while the drying temperature affected the water content, vitamin C, and acidity. The best formulation of Aloe-bignay instant drink is maltodextrin 30% and a drying temperature of 40°C.

A novel CeO2-ZnO-In2O3 nanocomposite for display applications and latent fingerprint detection in forensic science

An eco friendly and facile green combustion method is employed to synthesize CeO2-ZnO-In2O3 nanocomposite using Aloevera gel extract as a reducing agent followed by calcination to increase the emission properties in the blue region. The Bragg reflections of CeO2, ZnO and In2O3 confirms the formation of the NCs. However, the reflections corresponding to ZnO was found to be dominant. The crystallite size and other structural parameters such as strain, crystallinity, dislocation density and structural factor were determined. The surface morphology consists of highly agglomerated nanoparticles due to decrease in surface energy and adherence of particles with weak force. The direct energy band gap was found to be 3.06 eV. Further, the photoluminescence emission spectra, CIE and CCT coordinates clearly confirms the high intense emission in the blue region. The technique of powder dusting is used to visualize the latent finger prints. With a clear resolution, a well resolved ridge patterns for the identification of distinct latent finger prints are observed in the synthesized CeO2-ZnO-In2O3 nanocomposite. Thus, the present synthesized nanocomposite might be potential in blue light emission, fluorescence labelling and forensic applications.

In silico docking studies of alpha-amylase inhibitors from the methanol extract of Aloe vera

In the current study, potent inhibitors of a-amylase, one of the significant regulating enzymes in diabetes, were identified from the methanolic extract of Aloe barbadensis miller (Aloe vera), an indigenous herbal plant used to treat carbohydrate absorption problems such as diabetes and obesity. The Aloe vera gel extract was dried, ground, macerated with methanol and subjected to phytochemical screening, which was characterized by gas chromatography. Since there is a rapid increase in computational methods to predict the association between two molecules, molecular docking studies assessed the effect of AVM (Aloe vera methanol) extract in inhibiting the enzyme alpha-amylase. The molecules derived from GC-MS analysis were employed as ligands for the receptor α-amylase in molecular docking experiments. The protein target used in this study was the human pancreatic α-amylase with PDB-ID -2QV4. The protein target and ligand structures were obtained from PDB and Pubchem databases respectively and docking studies were performed using PyRx. In this study, we intended to find distinct phytochemical substances from the Aloe vera plant as α-amylase inhibitors with an objective that the molecular docking studies provided in this study might result in the discovery of effective α-amylase inhibitors for diabetic management.
