In vitro evaluation of antioxidant properties of Moringa oleifera, Centella asiatica, and Nigella sativa: individual and combined effects
No full textOxidative stress, a condition linked to various degenerative diseases, occurs when reactive species build up in the body. These harmful molecules often come by environmental factors like air pollution as well as by unhealthy lifestyle habits. Fortunately, nature gives a defense system: plants produce flavonoids and other phenolic substances that act as natural antioxidants, handling to neutralize reactive species and protecting the body by their damaging effects. The objective of the study was to determine the phytochemical content of extracts of M. oleifera leaf, C. asiatica leaf, and N. sativa Oil and their operation as antioxidants. The study applied both qualitative and quantitative phytochemical tests to measure flavonoid levels in the extracts. Bioactive substances were then identified through GC-MS and LC-HRMS, while antioxidant operation was assessed utilizing the DPPH method. The outcomes were drawn that Moringa oleifera and Centella asiatica extracts contained flavonoids, alkaloids, tannins, saponins, and steroids, while Nigella sativa oil contained terpenoids. Among the three, LC-HRMS screening drawn that Moringa oleifera extract had the highest diversity of flavonoid substances. The outcomes of GC-MS obtained 13 components identified in Nigella sativa oil, one of that was thymoquinone. The antioxidant operation IC50 scores were as follows: 57.943 ± 3.481 µg/mL (M. oleifera), 66.578 ± 1.979 µg/mL (C. asiatica), 56.174 ± 1.604 µg/mL (N. sativa), and 51.128 ± 1.724 µg/mL (polyherbal combination). All the samples demonstrated strong antioxidant operation, and notably, the combination of extracts proved to be more effective than when each to be utilized individually
Virtual screening of bioactive compounds from the lamiaceae family as acetylcholinesterase inhibitors for alzheimer’s disease
No full textAlzheimer's disease is a progressive neurological disorder that can impact adults aged 65 and beyond. A primary factor contributing to Alzheimer’s is the diminished availability of the neurotransmitter acetylcholine in the brain. Plants from the Lamiaceae family have been believed to possess potential as acetylcholinesterase inhibitors (AChEI) that can alleviate the symptoms of Alzheimer’s disease. This study aims to find possible bioactive compounds from plants of the Lamiaceae family, specifically Salvia officinalis L., Salvia lavandulifolia Vahl., Rosmarinus officinalis L., Collinsonia canadensis L., and Melissa officinalis L., as acetylcholinesterase inhibitors using in silico approaches. Active compounds from the Lamiaceae family were evaluated based on physicochemical properties, toxicity, Gibbs free energy (∆G), inhibition constant (Ki), absorption, excretion, metabolism, distribution, and molecular dynamics. From a total of 1,370 compounds derived from Lamiaceae plants, the compound 3,5,5-Trimethyl-4-[3-[3,4,5-trihydroxy-6-(hydroxymethyl) oxan-2]-yl]oxybut-1-enyl] cyclohex-2-en-1-one (TOC) from Salvia officinalis L. exhibited potential as an AChEI, possessing a molecular weight of 370 Daltons, 4 hydrogen donors, 7 hydrogen acceptors, a Log P partition coefficient of 3.46, a molar refractivity of 100, a Gibbs free energy change (∆G) of -11.2 kcal/mol, an inhibition constant (Ki) of 0.981 μM, and a total energy calculated via Molecular Mechanics Generalized Born Surface Area of 31.381 kcal/mol. In silico, the TOC ligand inhibits acetylcholinesterase to treat Alzheimer's
The phytochemical and antibacterial activity of ethanolic extract of Laportea decumana and Laportea aestuans
Full text linkPlants have been an important medicinal resource for centuries, offering a rich source of bioactive compounds used in traditional and modern medicine. This study aims to analyze the comparison between Laportea decumana and Laportea aestuans, focusing on the two main aspects, phytochemical screening and antibacterial activity. The extraction of the maceration process uses ethanol 96% as the solvent at room temperature for 72 hours. The qualitative phytochemical analysis uses HCl and FeCl3 0.1% reagents to determine flavonoids and phenolic compounds, respectively. The quantitative analysis of total flavonoid content is measured using colorimetric AlCl₃ method, while the determination of phenolic compounds is performed by the Folin-Ciocalteu. The diffusion method is used to determine the antibacterial activity. The 96% ethanol extract of L. decumana leaves has higher flavonoids (69.4 mg GAE/g extract) than phenolics (55.1 mg QE/g extract). However, the L. aestuans has higher phenolic content (55.3 mg QE/g extract) than flavonoids (35.3 mg GAE/g extract). The antibacterial test using agar diffusion method shows that both extracts inhibited the growth of pure strains of E. coli ATCC and S. aureus ATCC, with different potencies. The L. decumana extract showed 1.5 times stronger activity than the L. aestuans extract on the growth inhibitory activity against E. coli bacteria. The results show that the relationship between the antibacterial activity and the phytochemical profile against E. coli is strong but weak against S. aureus

Full text linkSpirulina (Spirulina platensis) and golden sea cucumber (Stichopus variegatus) are known to have antioxidant activity that has the potential to prevent neurodegeneration disease. The aim of this study was to examine the effect of the combination of spirulina and golden sea cucumber on Bcl2 gene expression in pyramidal hippocampus cells of trimethyltin-induced dementia (TMT) rats. The study used Sprague Dawley rats which were divided into 6 groups, namely the normal control group (CMC-Na and NaCl 0.9%), pain control (CMC-Na and TMT), positive control (citicoline dose 200 mg / kg and TMT) and test control injected with TMT and given a combination of spirulina and golden sea cucumber dose 200 mg/KgBB with three ratios namely 3: 1, 1: 1 and 1: 3. Extract and citicoline were given on day 1 to day 28, while TMT injection was given a single dose of 8 mg/KgBB on day 8. On the 36th day the rats were sacrificed, brains were removed and the right hemispherium cerebri was fed to 10% formalin in pbs. After 6 days the hippocampus was separated for immunohistochemical observation. The test result data was statistically analyzed with a one-way ANOVA test then followed by post hoc tukey to see the differences between groups. Results showed the combination of spirulina and golden sea cucumber can increase the expression of the Bcl2 gene in the hippocampus. The combination of spirulina and golden sea cucumber (ST1: 3) dose of 200 mg / kg body weight was able to increase hippocampus Bcl2 expression with the number of Bcl2 cell expression almost the same as citicoline in both CA1 and CA2-CA3 regions

Nicotine-free vape liquids containing essential oils of peppermint, lavender, and tangerine: safety and efficacy profiles
Full text linkDespite low nicotine levels, cigarettes and vape liquids can cause addiction, which makes quitting smoking difficult owing to withdrawal syndrome. Hence, we created a nicotine-free liquid vape using essential oils (EOs) like peppermint (Mentha piperita), lavender (Lavandula latifolia), and tangerine (Citrus reticulata) to substitute the nicotine in inducing relaxation without addiction. Thus, this study aimed to examine (1) the safety profile of this nicotine-free liquid vape by observing chemical characteristics using gas chromatography-mass spectrometry (GC-MS) and (2) its efficacy in reducing short-term anxiety in healthy volunteers who had previously used nicotine vape. The most complicated vape liquid formula (F4), containing propylene glycol, vegetable glycerin, with those three EOs, was injected into GC-MS, and the mass spectra were compared to the Wiley mass spectral library to identify the compound name. For the efficacy test, subjects who met inclusion criteria and fulfilled informed consent were randomly assigned to five groups (four groups received test liquids formula (F1-F4) while one group received placebo). Before and after using the vape liquid, subjects were asked to complete the State-Trait Anxiety Inventory (STAI) questionnaire to assess its anxiety-reduction effects. The result showed that nicotine-free vape liquids containing three EOs did not show any foreign substances that had never been encountered before, which means our product is safer than nicotine-containing vape liquids. This safety was also supported by all study subjects who did not report any adverse effects. The efficacy test showed that subjects who used vape liquids with essential oils (F1-F4) experienced a significant decrease in heart rate and systolic blood pressure. At the same time, 50% had a lower post-test STAI score, indicating a decrease in anxiety, although it was not statistically significant
