Development of FTIR-ATR spectra and PLS regression combination model for discrimination of pure and adulterated acacia honey

A Fourier Transform Infrared Spectroscopy and attenuated total reflectance (FTIR-ATR)-based chemometric model was evaluated for the rapid identification and estimation of adulterants in honey. Two types of honey, bee honey and stingless bee honey, were adulterated with acid adulterants (acetic acid, citric acid, and tamarind extract) at different concentrations of 1%, 3%, 5%, and 7% and sugar adulterants (liquid corn syrup, cane sugar, palm sugar, and inverted sugar) at different concentrations of 1%, 2%, and 3%. The physicochemical properties (Brix, moisture content, pH, and free acidity) and sugar contents (glucose, fructose, and sucrose) of each type of honey and their adulterated samples were determined before FTIR analysis. For all the samples, FTIR spectra were acquired in the mid-infrared range (400-3600 cm−1) and the spectra obtained were subjected to partial least squares (PLS) analysis to develop the model for the determination of adulterants in honey samples. The PLS model produced high coefficient of determination (R2) for bee honey adulterated with acetic acid (0.95), citric acid (0.98), tamarind extract (0.97), and stingless bee honey adulterated with liquid corn syrup (0.99), inverted sugar (0.91), cane sugar (0.86), and palm sugar (0.77). A recognition model was developed for mixture detection and verified through the physicochemical analysis. The combination of FTIR-ATR spectra and the PLS regression model can be a fast, reliable, nondestructive method to detect honey adulteration.

Low environmental temperature alters behaviour and physiologic responses leading to low productivity in poultry. This study was designed to evaluate the effect of orally administered aqueous crude extracts of Persea americana and Tamarindus indica in broiler chickens during cold season. Twenty-eight, 3-week old Arbor acres mixed sex broiler chickens were used. Seven broiler chickens were assigned each to Cg (control), TA (20% avocado aqueous extract), TB (20% aqueous tamarind extract) and TC (20% aqueous avocado extract + 20% aqueous tamarind extract). The treatmentswere administered as sole drinking water while the control received plain water. Thermal environmental data during the study period were measured, using a dry and wet bulb thermometer and relative humidity using a table, while the temperature humidity index was calculated. Cloacal temperature and blood samples were collected on days 28, 35 and 42 of the experimental periods. The Results show that the experimental period was thermally stressful (cold stress). Mean cloacal temperatures of broiler chickens in all the treatment groups were significantly (P < 0.05) higher (41.0 - 42.3°C) than those in control group (41.0 – 41.4°C) on days 28, 35 and 42. The heterophil/Lymphocyte ratio, pack cell volume, heamoglobin, total protein, total white blood cell, total red blood cell, weight gained were higher (P > 0.05) in treatment groups compared to control group. It was concluded that aqueous extracts of Persea americana and Tamarindus indica singly or in combination ameliorated cold-stress and improved broiler performance during cold-dry season

Mycoplasma and Neisseria Prevalence in Asymptomatic Women and Investigation of their Susceptibility to Tamarindus indica and Syzygium aromaticum Aqueous Extracts

Neisseria and Mycoplasma are two prevalent bacteria in the female urogenital tract leading to gynecological infections and infertility. The aim of this study was to assess the antibacterial activity of Tamarindus indica and Syzygium aromaticum extracts against Neisseria and Mycoplasma isolates. It was a cross cectional study on 60 asymptomatic women at the Protestant and Regional Hospital of Ngaoundere. For this reason, a large consecutive sample of patients with several well-defined characteristics was assembled and urine and cervical-vaginal swab were collected using standard procedures. After being isolated on a specific medium, several strains of Neisseria and Mycoplasma were identified based on their morphological and biochemical characteristics. The antibacterial activity of the plant extracts was tested using the agar-well diffusion method. It was discovered that 70% of asymptomatic women had overall infection, with varying prevalence rates. The prevalence rates of Neisseria and Mycoplasma were 14.29% and 85.71% respectively. The aqueous extracts of Syzygium aromaticum against Neisseria produced inhibitory diameters of 43 mm, 40 mm and 32 mm at doses of 20 mg/mL, 10 mg/mL, and 5 mg/mL, respectively while, at the same doses, the aqueous extract of Tamarindus indica produced inhibitory diameters of 16 mm, 14 mm and 13 mm, respectively. The combined extract of Syzygium aromaticum and Tamarindus indica exhibits inhibitory diameters of 25, 23, and 30 mm at 20 mg/mL, 10 mg/mL, and 5 mg/mL, respectively. Syzygium aromaticum extract alone showed efficacy against Mycoplasma, with diameters of 16.5 mm, 13 mm and 10.5 mm at concentrations of 20 mg/mL, 10 mg/mL, and 5 mg/mL respectively. Inhibition diameters of 18 mm (for fosfomycin and ofloxacin), 22 mm (for chloramphenicol and ceftriaxone) and 26 mm (for levofloxacin) were found using Neisseria isolates. The only drugs that demonstrated efficacy against Mycoplasma were Minocycline and Josamycin. Given these findings, extracts of Syzygium aromaticum and Tamarindus indica can be investigated and used to treat infections caused by Niesseria and Mycoplasma.

The liquid chromatography mass spectrometry revealed the presence of some important metabolite; linoleic acid and quassin, among others, which are antioxidant. Based on the results obtained, the T. indica leaves contain vital metabolites with antioxidant potential that could be useful in health management.

Anti-fertility and abortifacient activity of hydroalcoholic fruit pulp extract of Tamarindus indica

BackgroundMedicinal plants have been widely used for treatment and management of various diseases. There are many different types of commercialized synthetic contraceptives on the market today for controlling fertility, these cannot be utilized since they have serious side effects such weight gain, hormonal alterations, hypertension, and cancer . In India, indigenous women from Tripura & Maharashtra have historically utilized the fruit pulp of Tamarindus Indicus to induce abortion. However, there is currently no accessible scientific data supporting the use of this plant for fertility control. MethodsThe current study's objective was to evaluate the hydroalcoholic extract of Tamarindus indica fruit pulp's ability to induce abortion in female Wistar rats. In this experimental animal model, contraceptive activity of hydroalcoholic extract of Tamarindus indica (HAETI) was evaluated for anti-implantation, abortifacient, and estrogenic/antiestrogenic action. Female rats having ovariectomies were given HAETI extract (500 mg/kg) for 7 straight days to test to evaluate the estrogenic/anti-estrogenic action. All animals were killed on the eighth day, and the blood serum was then processed to determine the levels of several hormones, including LH, FSH, prolactin, estrogen, and others, as well as biochemical markers including cholesterol, total protein, glycogen, and alkaline phosphates. In this model, modifications to uterine histoarchitecture were also investigated. The extract was administered from the 1 to7 day of pregnancy. On 10th day, laparotomy was performed to evaluate the no. of implants in female rats. ResultsSteroids, flavonoids, saponins, tannins, and alkaloids were detected during phytochemical analysis of the extract. the HAETI extract demonstrated significant anti-implantation and abortifacient effects. Additionally, the extract demonstrated significant estrogenic activity as evident by uterine histological parameters including increases in endometrium thickness and height, vaginal cornification. Further, the study found marked increases in glycogen, alkaline phosphate, estrogen, cholesterol levels when given alone or in combination with estradiol valerate. LH, FSH, and a little increase in prolactin levels were suppressed after HAETI administration. ConclusionsOur study's findings showed that Tamarindus indica fruit pulp hydroalcoholic extract has a potent contraceptive effect, which may be explained by the phytoconstituents of the plant's capacity to inhibit implantation and have an estrogenic effect. Further investigation on Tamarindus indica as a potential natural anti-implantation agent allow for new abortive drug.

Antiproliferative effect of methanolic extract of Tamarindus indica in C127I cell line

Investigation of natural bioactive compounds that possess antioxidant and anticancer properties have drawn interest in scientific and industrial perspectives. The current study was conducted to assess the antiproliferative action of methanolic extract of seed coat of Tamarindus indica in C127I mouse mammary tumour cell line. 3-(4,5-dimethyl thazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT) assay is performed to assess the cytotoxicity of methanolic extracts of T. indica in the C127I cell line at concentrations of 320, 160, 80, 40, 20, and 10 µg/mL. The half maximal inhibitory concentration (IC50) was then calculated using Graph Pad Prism 5.0. Doxorubicin was used as positive control. After determining IC50, the cells were treated with extract of T. indica at half, IC50 and double IC50 concentrations after being seeded at a concentration of 1x105 cells/mL in 6 well plates. After 24 hours the cells were trypsinised and stained with acridine orange-ethidium bromide (AOEB) to assess the morphology of apoptosis. When the cells were exposed to various doses of the extract, a dose-dependent decrease in cell viability was observed, and the IC50 value of T. indica was estimated to be 13 µg/ml. In the control cells, AO/EB labelling revealed proliferating cells with green fluorescence, but the T. indica extract-treated cells displayed dose dependent shift from orange to red fluorescence. In conclusion, methanolic extract of Tamarindus indica was found to possess antiproliferative effect in C127I cell line comparable to doxorubicin.

Response of Rice (Oryza sativa L.) Varieties to Salicylic Acid, Potassium Silicate and Tamarind Extract in Saline Soils of Kano River Irrigation Scheme Nigeria

The experiment was carried out in the Eastern and Western sectors of Kano River Irrigation Scheme, Kano State latitude 11º 45’N and 12º 05’ N and longitude 8º 45’ E and 9º 05’ E in the Sudan Savanna Agro-ecology of Nigeria, during the dry season of 2020 and 2021. The experiment was therefore conceived with the aim of introducing improved salt tolerant varieties to farmers in addition to enhancing their tolerance using synthetic and natural plant growth regulators. The treatments consisted of four rice varieties made up of 2 salt tolerant accessions {Arica 1 and Arica 2, 1 blast resistant variety (Gawal R1) and a variety (FARO 44) as a check} these were factorially combined with foliar application of salicylic acid (0.2g in 1L of water), potassium silicate (16 g/L-1 of K2SiO3), tamarind extract 8% (320ml of extract in 1 liter of water) and a zero control (0). The treatments were laid out in a Randomized Complete Block Design (RCBD) which consisted of 16 treatments replicated six times with a farmer constituting a replication. Results have shown that plant height, leaf area index (LAI), photosynthetically active radiation (PAR), chlorophyll content and the yield were all significantly affected by varietal differences except total number of tillers per plant in 2020. However, in 2021 LAI, PAR and chlorophyll content were not significantly affected by differences due to varieties but the remaining characters differed significantly. Exogenous factors had no effect on all the characters in 2020 but significantly influenced the chlorophyll content, total number of tillers and the yield in 2021. Arica 1 and Faro 44 gave the highest yield. Among the exogenous factors Tamarind extract had significantly heavier paddy yield than the control but was similar to other exogenous factors in terms of effectiveness. Tamarind extract could therefore be suggested to farmers when growing rice under saline or sodic condition in the irrigation scheme due to its lower cost and availability.

Sour Tamarind Is More Antihypertensive than the Sweeter One, as Evidenced by In Vivo Biochemical Indexes, Ligand-Protein Interactions, Multitarget Interactions, and Molecular Dynamic Simulation.

This research investigated the antihypertensive effects of tamarind products and compared their potentials based on an animal model's data verified by molecular docking, multitarget interactions, and dynamic simulation assays. GC-MS-characterized tamarind products were administered to cholesterol-induced hypertensive albino rat models. The two-week-intervened animals were dissected to collect their serum and organs and respectively subjected to analyses of their hypertension-linked markers and tissue architectures. The lead biometabolites of tamarinds interacted with eight target receptors in the molecular docking and dynamic simulation studies and with multitarget in the network pharmacological analyses. The results show that the serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), C-reactive protein (CRP), troponin I, and lipid profiles were maximally reinstated by the phenolic-enriched ripened sour tamarind extract compared to the sweet one, but the seed extracts had a smaller influence. Among the tamarind's biometabolites, ϒ-sitosterol was found to be the best ligand to interact with the guanylate cyclase receptor, displaying the best drug-likeliness with the highest binding energy, -9.3 Kcal. A multitargeted interaction-based degree algorithm and a phylogenetic tree of pathways showed that the NR3C1, REN, PPARG, and CYP11B1 hub genes were consistently modulated by ϒ-sitosterol to reduce hypertension and related risk factors. The dynamic simulation study showed that the P-RMSD values of ϒ-sitosterol-guanylate cyclase were stable between 75.00 and 100.00 ns at the binding pocket. The findings demonstrate that ripened sour tamarind extract may be a prospective antihypertensive nutraceutical or supplement target affirmed through advanced preclinical and clinical studies.

Cream from a mixture of turmeric and tamarind leaves extract needs to be tested for its toxicity to really make sure it doesn't have side effects. The purpose of this study was to test the toxicity of a mixture of turmeric and tamarind leaves extract cream using Wistar rats. This study used rats as experimental animals which were carried out in 2 stages, namely preliminary tests using 5 groups of experimental animals. After adaptation the experimental animals were given cream doses of 50, 200, 1000, 2000 mg/kg bw. The second stage was carried out after the results of the first stage showed symptoms of toxicity and death. The second stage used two groups of rats (3 each), namely the treatment group using the largest dose of cream that did not cause death and the control group which was a placebo. In addition, observations of collagen content were also carried out. The results showed that the turmeric and tamarind extract cream did not have toxic properties. The skin of rats that were given turmeric and tamarind extract cream produced higher collagen content and was different from the other groups.

Gastric pyrosis and hyperacidity: an outstanding task in clinical practice. The positioning of a new multicomponent medical device containing sodium alginate, tamarind seed extract, and carbonates

Gastric pyrosis associated with hyperacidity is a common symptom affecting up to 20% of the Western population. Pyrosis may depend on organic or functional digestive disorders, including gastric reflux, esophago-gastro-duodenal inflammatory diseases, dyspepsia, and gastrolesive drug use. A new medical device (Piromal®) has been recently marketed in Italy. This medical device contains tamarind seed extract, alginate, and carbonates. These components exert important activities. First, tamarind extract contains xyloglucans (polysaccharides) with mucin-like activity, acting as a protective agent. Second, alginate exerts a well-known antireflux activity. Finally, carbonates display a relevant buffering activity. These three components provide prompt symptom relief and guarantee adequate protection of digestive mucosa. In addition, tamarind extract and alginate promote the repair and regeneration of damaged mucosa. Based on this background, a practical algorithm for managing patients with pyrosis associated with hyperacidity is proposed.
