    Opis:
    The present study was quantitative analysis and antimicrobial activity of petroleum ether, chloroform, ethyl acetate, methanol root extracts. The gram positive and gram negative bacterial and fungal species by the disc diffusion method at various concentration (250μl-1000μl). The results was present in the phenolic and flavonoid content compared to extracts. All the root extract against to Bacillus subtilis and Streptococcus pyogenes and fungal species Candida albicans at highest inhibition at concentration of methanolic root extract of zone formation. The preliminary studies on Decalepis hamiltonii root extract exhibited their antimicrobial potential which could be exploited further and future pharmaceutical, therapeutic efficiency and food preservation and applications.

    Opis:
    The present communication reports a rapid, uncomplicated, sustainable and facile method of eco-friendly synthesis of silver nanoparticles (AgNPs). The pressing need for the development of benign, profitable and eco-friendly alternative routes has inspired researchers to explore plant extracts as safer replacements to hazardous chemicals. In the present study, a benign method of synthesis of AgNPs using Soymida febrifuga aqueous root extract has been developed. The characterization studies of synthesized AgNPs revealed spherical morphology and crystalline nature of AgNPs. The average particle size was 21.81 nm. The synthesized AgNPs were employed as mercury nanosensor for the selective and sensitive detection of toxic mercury ions in water and soil samples. The AgNPs showed a marked visual color change and change in surface plasmon resonance band on interaction with mercury ions. The greater selectivity of AgNPs towards mercury ions was observed. The limit of detection of mercury by 100 μL of colloidal AgNPs was found to be 2×10-4 M visually and 1.332×10-5 M spectrophotometrically in water samples and ×-4 M visually and 22.3×10-5 M spectrophotometrically in soil samples. The method makes use of a small quantity of AgNPs for detection of mercury in water and soil samples. The method proposed in the present study provides a rapid, selective and sensitive method for detection of mercury ions in environmental water and soil samples. The synthesized AgNPs were also used as effective microbicidal agents. The microbicidal potential of the synthesized AgNPs was checked against two gram positive and gram negative bacterial strains.

    Opis:
    Plant extracts have been used widely with and without chemical modification for various infectious diseases cause by bacterial activities. All the methanolic plant extract of Sclerocarya birrea showed anti-microbial activities against most of the test organism with some showing a better antibacterial and antifungal activities than others. The leave from Kem has the minimum bactericidal/fungicidal concentration of 50 mg/ml for E. coli, 100 mg/ml for C. albican and S. aureus but A. niger has 200 mg/ml whereas on the other hand from Yola S. aureus, C. albican, A. niger and E. coli has 100 mg/ml. The stem has the minimum bactericidal and fungicidal concentration of 50 mg/ml for E. coli, S. aureus and 100 mg/ml for C. albican and A. niger and on the other hand from Yola has 100 mg/ml for E. coli, S. aureus and 200 mg/ml for C. albican and A. niger. The roots from Kem has 50 mg/ml for E. coli and S. aureus and 100 mg/ml for C. albican and A. niger and from Yola has 100 mg/ml for E. coli, S. aureus, C. albican and A. niger has 200 mg/ml. This shows that the stem and roots of Sterculia Setigera is more sensitive to the tested organism and is bactericidal at low concentration. The leaves extract in both locations has the MIC of 50 mg/ml for E. coli, S. aureus and C. albican but 100 mg/ml for A. niger. The stem extract from Kem has the MIC of 25 mg/ml for bacteria and 50 mg/ml for fungi and on the other hand from Yola, the extract has MIC of 50 mg/ml for E. coli, S. aureus and C. albican but 100 mg/ml for A. niger. The root showed different minimum inhibitory concentration from Kem, the extract has 25 mg/ml for bacteria and 50 mg/ml for fungi. On the other hand, the extract from Yola has 50 mg/ml for bacteria and 100 mg/ml for fungi. Finally, the limit of detection for both plants collected from two different geographical areas for inhibitory effect has been measured successfully.

    Opis:
    The study was carried out to evaluate the phytochemical constituents, antioxidant activity and the content of total phenolic and flavonoid in the methanolic extract from stem bark, root, and leaves of Rhizophora mucronata from Karangsong, Indramayu Regency, West Java, Indonesia. The antioxidant activity was evaluated using 2,2-diphenyl-1-picrilhydrazyl (DPPH) assay. Total phenolic and flavonoid contents were determined according respectively to Folin-Ciocalteau method, and aluminium trichloride method. The methanol extract from stem bark of R. mucronata contained secondary metabolite such as phenolic, flavonoid, tannin and saponin. The stem bark of R. mucronata showed the highest phenolic and flavonoid content and possessed a higher antioxidant activity (IC50 84.80 µg·m/L) than that of root (IC50 166.95 µg·m/L) and leaves (IC50 90.51 µgmL1). Total phenolic and flavonoid content in the stem bark of R. mucronata were 131.91 ±1.7 mg gallic acid equivalents/g and 902 ±0.7 mg quercetin equivalents/g, respectively.
