The aim of the study was to perform comprehensive phytochemical analysis, UHPLC, ATR-FTIR profiling and evaluation of various biological activities of N. Indica rhizome. The phytochemical analysis indicated presence of alkaloids, saponins, and triterpenes. In the antioxidant assay, the methanolic (IC50 40.3±0.04) and chloroform fractions (IC50 40.05±0.21) showed highest DPPH inhition. Like wise, methanolic fraction showed highest FRAP value (756.2±0.06) followed by chloroform (225.0±0.04) and ethyl acetate fractions (193.0±0.21). In the antimicrobial assays, chloroform (MIC <  0.156 mg/ml) and methanol fractions (MIC 0.625 mg/ml) fractions showed significant inhibition of Klebsiella pneumoniae. Also a significant antibiofilm of biofilm formation was recorded by chloroform (IC50 1.73 mg/ml) and ethyl acetate fractions (IC50 1.76 mg/ml). It was concluded that the N. Indica rhizome posess antioxidant, antimicrobial and antibiofilm potential, that may be attributed to high flavonoid contents.

  Objective: The aim of the present study was to investigate in vitro antibacterial, antifungal, and antioxidant activities of different solvent extracts of Garcinia mangostana leaves.Methods: The powdered leaf was subjected to sequential extraction using hexane, ethyl acetate (EA), and methanol. The extracts were subjected to quantitative and qualitative phytochemical analysis, antimicrobial, and antioxidant activities. The best solvent extract was subjected to gas chromatography–mass spectrometry (GC-MS) analysis.Results: The highest activity was recorded in EA extract which was subjected to GC-MS analysis revealing the presence of squalene (17.09%).Conclusion: From this present study, we conclude that EA is the best solvent for extracting antimicrobial and antioxidant compounds from the leaves of G. mangostana.

Plant-derived digestive enzyme inhibitors particularly those targeted to carbohydrate metabolism has been the focus of recent studies as natural supplements for weight control and diabetes. The present study explores the salivary amylase inhibition activity of Garcinia mangostana (Linn.) pericarp extracts and Carica papaya (Linn.) leaf extracts and fractions, as well as perform phytochemical screening and quantification, and thin layer – and high performance liquid chromatographic profiling. ­Results show that crude extracts and purified fractions were able to inhibit salivary amylase, with C. papaya fraction 1 being the most active at 30.89% inhibition. Phytochemical screening of all extracts tested ­positive for tannins, glycosides, phenolics, flavonoids and alkaloids. Quantification of phenolics showed that extracts contained high levels of phenolics, with C. papaya crude extract having the highest content with 219.0±12.7 mg GAE/g extract followed by G. mangostana crude extract with 247.1±18.0 mg GAE/g extract. Quantification of total flavonoids also showed C. papaya crude extract to contain the highest content with 55.12±0.679 mg QE/g extract. All extracts contained negligible alkaloid content, though. HPLC and TLC profiling showed several peaks and bands, when viewed in 210 nm and UV light, respectively. These results demonstrate in vitro the salivary amylase inhibitory activity of both plants and their potential as antidiabetic drug candidates; however, further studies need to be done, like isolation and structure elucidation of active components and toxicity assays. Keywords: Amylase inhibition, phytochemical quantification, Carica papaya, Garcinia mangostana

The presented work represents phytochemical analysis, Antioxidant assay and Antimicrobial activity of Bhut jolokia pepper (Capsicum chinense Jacq) extracted by ethanol as solvent. The ethanolic extract of Bhut jolokia pepper showed the presence of terpenoids, steroids, saponins and flavonoids. Antimicrobial assay was done with varying concentration (250-1000µg/ml) of pepper extract using tetracycline as control by well diffusion method, the extract at 750µg/ml shown best inhibition zone and Staphylococcus aureus showed the highest zone of inhibition at all concentration compared to other bacteria species with maximum zone of inhibition of 27mm. The DPPH scavenging assay for antioxidant activity at 517nm showed positive activity for scavenging, scavenging increased with the concentration of extract. Thus, Bhut jolokia could be effective in treating diseases caused by Staphylococcus aureus from antimicrobial assay result.

The antioxidant capacity of the crude extract and fractions ofTabernaemontana catharinensis fruits and branches, was evaluated by the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and the content of polyphenols, flavonoids, alkaloids and condensed tannins were determined by the spectrophotometric method. The ethyl acetate fraction of the fruits and the n-butanol fraction of the branches showed IC50 of 181.82 µg/mL and 78.19 µg/mL, respectively. All fractions were analyzed by high performance liquid chromatography (HPLC), in the branches were quantified chlorogenic acid in the chloroform (8.96 mg/g), ethyl acetate (4.31 mg/g) and n-butanol (3.33 mg/g) fractions; caffeic acid in the ethyl acetate (5.24 mg/g) and n-butanol (1.81 mg/g); gallic acid (0.52 mg/g) in the n-butanol. In the fruits, chlorogenic acid in the chloroform (1.67 mg/g); rutin in the ethyl acetate (3.45 mg/g) and n-butanol (8.98 mg/g) fractions. The present study showed that these quantified compounds can contribute to antioxidant capacity which was higher in the branches than in the fruits.

The aim of this study was to investigate the antibacterial effect and identify the phytochemical constituents of Moringa oleifera leaves and seeds extract on Staphylococcus aureus (S. aureus) clinical isolates using agar well diffusion method. The samples were collected from the premises of Usmanu Danfodiyo University, Sokoto. The Seeds and Leaves were collected fresh. They were extracted using methanol and ethyl acetate. Various concentrations from 100mg/ml to 500mg/ml were prepared. The test bacteria used is Staphylococcus aureus obtained from Microbiology laboratory of the Usmanu Danfodiyo University. The bacteria were re-identified using biochemical tests. The bacterial inoculums were standardized to McFarland scale 0.5. Zone of inhibition were read after 24 hours of incubation at 370C.The results of the antibacterial study revealed that the methanolic leaves extracts at 500 mg/ml had effect on S. aureus with zone of inhibition of 20mm. The methanolic seed extract have effect on S. aureus with zone of inhibition of 19.5mm. The MIC for the leave and seed extracts for Staphylococcus aureus was 250mg/ml. The MBC was 500mg/ml. The results of the phytochemical analysis revealed the presence of flavonoid, tannins, saponins, cardiac glycosides, alkaloids, volatile oil, saponin glycosides, and glycosides but anthraquinone and steroids were absent in the extracts. The zones of inhibition showed that both the methanolic and ethyl acetate extracts at 500mg/ml were active to all the tested bacteria. ANOVA and Duncan Multiple Mean Range test was used to analyze the data. Based on Duncan’s grouping, there is significant difference between the solvents and the concentrations used.

For thousands of years, truffles have been used as essential foods in different cultures around the world because of their rich nutritional value and their pleasant and characteristic smell. We have studied the effect of truffles (Tirmania Nivea and Tirmania Pinoyi) extracts on the antioxidant stress properties issued from the Moroccan desert. Antioxidant and anti-free radical activities were studied using three analytical methods: trapping capacity of 1,1-diphenyl-2-picrylhydrazyl, phosphomolybdate, and reducing ferric antioxidant capacity; in addition, phenol and flavonoid levels were measured. The results of the FRAP, DPPH and PPM tests of T. Nivea were respectively 4.112±0.217, 0.142±0.006, 2.235±0.110 mg/mL for methanols and 3.424±0.034, 0.137±0.025, 0.858±0.010 mg/mL for ethyl acetate extracts. The results of the tests of T. pinoyi were respectively 3.670±0.572, 0.102±0.004, 0.907±0.014 mg/mL for methanols and 3.404±0.096, 0.080±0.003, 0.693±0.057 mg/mL for ethyl acetate extracts. For this work, we propose a valorization of the Moroccan truffle in the prevention of oxidative stress.
