In the present work, we report the phytosynthesis of AgNPs mediated by leaf and seed extracts of Synsepalum dulcificum. The extracts catalyzed the formation of brown colloidal AgNPs, which stabilized in 10 min. The leaf and seed AgNPs yielded surface plasmon resonance at andThese showed the involvement of phenolic compounds and proteins in the phytosynthesis.

The particles were fairly spherical and crystalline in nature having size of 4—26 nm, with prominence of silver in the colloidal solutions. The particles inhibited the growth of drug-resistant strains of Pseudomonas aeruginosa and Klebsiella granulomatis with zone of inhibition of 11—24 mm. Also, the phytosynthesized AgNPs completely inhibited the growth of Aspergillus flavus and Aspergillus niger.

Similarly, the particles displayed blood anticoagulant activities as well as achieved thrombolysis.The AgNPs can be explored for biomedical and catalytic applications.

The report is the first on the eco-friendly synthesis of nanoparticles by S. The fabrication of nanoparticles through green route has attracted special attention of scientists in the growing area of nanotechnology because of the simplicity of procedure, the nonuse of hazardous chemicals or techniques, the low consumption of energy, and the increased level of biocompatibility for applications in the living systems.

In addition, the large-scale production of nanoparticles can be easily achieved through this means, whereas the abundance of biomolecules that can serve as bioreductants in the green synthesis of nanoparticles in diverse living things also contributes enormously to the growing trend in green nanotechnology.

In this regard, biomolecules obtained from bacteria [ 1 ], [ 2 ], [ 3 ], fungi [ 4 ], [ 5 ], [ 6 ], macro- and microalgae [ 7 ], [ 8 ], [ 9 ], [ 10 ], arthropods [ 11 ], [ 12 ], and different parts of green plants [ 13 ], [ 14 ], [ 15 ], [ 16 ], [ 17 ] have been used to synthesize a wide range of nanoparticles under ambient conditions.

We have documented the use of microbial enzymes [ 18 ], [ 19 ], Cola nitida seeds, seed shell and pod [ 20 ], [ 21 ], cocoa pod husk [ 22 ], spider cobweb [ 23 ], and culture supernatant of Bacillus safensis [ 24 ] to synthesize AgNPs. These particles have shown tremendous biomedical properties.

Among diverse metallic nanoparticles that have been studied, AgNPs occupy prime position because of several applications alluded to them. Their optical, electronic, catalytic, antimicrobial, and electrochemical attributes have greatly influenced their relevance in diverse areas such as in food, health care, agriculture, biomedical, environmental, textile, and catalytic applications [ 25 ]. Suffice to say that the list of applications of AgNPs seems endless as new areas of relevance emerge very often.

The green synthesis of AgNPs also contributes to the upsurge in the applications of AgNPs, as the improved compatibility with biological systems through the avoidance of hazardous procedures is achieved. Therefore, newer sources of biomolecules from diverse living entities are continually sought to catalyze the biological synthesis of nanoparticles for various applications in different areas of human endeavors.

An important emerging area of application of biosynthesized AgNPs is in the management of blood coagulation disorders, whereby nanoparticles can be used to prevent aggregation of platelets [ 26 ] to inhibit blood coagulation.

Similarly, nanoparticles can be used alone or as carriers of active drugs for the efficient and timely dissolution of blood clots, thereby preventing the untold outcome of the formation of blood clot thrombus , which may include ischemia or stroke arising from blood coagulation and cardiovascular disorders.

Miracle fruit plant Synsepalum dulcificum is a shrub tree native to the rain forest zone of Africa and popularly known for the production of a glycoprotein sweetener miraculin in its fruit.

The fruit as the source of miraculin can be used for the control of diabetes, whereas several other active principles, including pigment and phytochemicals, can be formulated into pharmaceutical products [ 27 ]. Owing to richness in biologically active phytochemicals, different parts of the plant have been used in folklore medicine. The leaves have been reportedly used to treat diabetes, malaria, hyperthermia, hemorrhoids, and enuresis, and the seeds can be used for the treatment of stomach ache, anemia, and obesity [ 28 ], [ 29 ].

Similarly, the roots of the plant have been used in the treatment of cough and tuberculosis, and the bark is used to manage prostate problems [ 28 ]. In this work, the usefulness of leaf and seed extracts of S. To the best of our knowledge, this work is the first to report the utilization of S.

Fresh leaves and berries of S. The powdered samples were kept at room temperature for further use. The powdered samples were extracted with NaOH, by dissolving 0. The mixtures were cooled to room temperature, followed by centrifugation at rpm for 30 min. The hydrolysates obtained were used without further purification.

Extracts obtained from the leaf and seeds of S. The timely development and stabilization of color as function of the formation of AgNPs were monitored. Both leaf and seed-mediated AgNPs were investigated for their antimicrobial activities using some established cultures in our laboratory. In the antifungal assay, the method of Khatami et al. Thereafter, fungal plugs of 6-mm diameter h-old cultures of Aspergillus flavus , Aspergillus niger , and Aspergillus fumigatus were used to inoculate PDA plates at the center.

The control plates that were not exposed to AgNPs and those exposed to the extracts were also set up. The percentage growth inhibition was obtained; thus,. Mixtures of the dye and extracts alone were set up as control samples. The mixtures were kept on rotary shaker at rpm for up to 24 h. At periodic intervals, samples were taken, and absorbance readings were obtained. The degradation of malachite green was determined; thus,. AgNPs were investigated for their anticoagulant properties using the blood sample freely given by a healthy donor.

A series of control experiments were set up, and these included a collection of blood into an ethylenediaminetetraacetic acid EDTA container positive control and an ordinary clean bottle negative control. Microscopic investigation of the samples was undertaken by smearing blood samples on clean, grease-free slides and observed under the Olympus microscope. The determination of thrombolytic activities of AgNPs was conducted as previously described [ 31 ] by treating preformed blood clots with 0.

Similarly, control samples were set up by treating blood clots with the extracts of S.Microscopic images of the contents were also obtained. Both leaf and seed extracts of S. The color stabilized in 10 min, with more intense color recorded in leaf AgNPs.

The change in color of metallic salt solutions is a manifestation of the formation of nanoparticles. The formations of different shades of color, including light yellow and yellow brown to dark brown colloidal AgNPs, are widely reported in literature [ 1 ], [ 18 ], [ 20 ], [ 23 ], [ 24 ], [ 32 ], [ 33 ].

The nature of bioreductant molecules largely influences the excitation of reduced particles, thereby leading to the development of different shades of color. Schematic view of the biosynthesis of AgNPs using leaf and seed extracts of S. The nanoparticles absorbed maximally at wavelengths of andThe broadness of the spectra may be indicative of fair incidence of polydispersed particles.

The absorbance values are within the range of , ,The reddish brown colloidal AgNPs produced by the leaf extract of pineapple also yielded maximum absorption between and nm [ 32 ].

The higher absorbance readings obtained for leaf AgNPs clearly indicated the formation of more nanoparticles than in the seed AgNPs, and this may be attributed to the abundance of bioreductant molecules in the leaf of S. All these indicate that the hydroxyl group of phenolic compounds and proteins in the extracts might have formed layers on the particles as capping molecules to prevent aggregation of the AgNPs.

Leaves of S. It is evident from the foregoing that the leaves and seeds of S. The leaf AgNPs Figure 4A 1 were well dispersed, whereas little agglomeration was noticed in seed AgNPs Figure 4B 1 , which might be as a result of sedimentation at the latter stage of synthesis as similarly observed by Ahmad et al. The agglomeration brought about few incidences of nonspherical and bigger particles. The AgNPs inhibited the growth of P.

However, the plant extracts were not active against the drug-resistant isolates.The antibacterial activity of AgNPs is well established in literature [ 7 ], [ 18 ], [ 20 ], [ 21 ], [ 23 ], [ 24 ], [ 32 ], [ 41 ] as obtained in this study. However, it is worth mentioning that AgNPs produced in this work acted against resistant bacteria, indicating that the particles may have biomedical importance to combat drug-resistant bacteria in the environment.

The scourge of resistant bacteria is appalling as previously established in some of our investigations [ 43 ], [ 44 ], [ 45 ], [ 46 ]. There was no inhibition of growth in control experiments. These results are in agreement with those earlier established [ 21 ], [ 30 ], [ 33 ]. Results of the present work showed that AgNPs can serve as potent antifungal agents. The antifungal activities can be a result of cell wall attack and destruction of spores, which promote the outflow of intracellular constituents and, consequently, death.

Antifungal activities of the biosynthesized AgNPs using leaf and seed extracts of S. The degradation was steady and concentration dependent in both leaf and seed AgNPs, whereas exposure to extracts alone did not lead to degradation of malachite green data not shown. The use of nanoparticles as obtained in this study for the degradation of dyes is reported in literature [ 47 ], [ 48 ], [ 49 ], with some advantages over conventional techniques of absorption, adsorption, coagulation, flocculation, ultrafiltration, reverse osmosis, and membrane technologies that only involve concentration or transferring of organic compounds from one form to another [ 50 ].

However, in the present study, the catalytic degradation of malachite green was achieved without the use of NaBH 4 and exposure to light.Within 3 h, the degradation of malachite green atThe underlying mechanism of dye degradation of dyes by nanoparticles had been captured in an electron relay effect [ 51 ], whereby nanoparticles mediate in transferring electron between biomolecules borne on nanoparticles and the dye for the catalytic degradation of dye.

Results obtained in this work have further shown the practicability of the applications of biosynthesized AgNPs for the catalytic degradation of malachite green. Degradation of malachite green by biosynthesized AgNPs using leaf and seed extracts of S.

Both leaf and seed AgNPs displayed excellent blood anticoagulant activities Figure 8 , which prevented the blood samples from clotting.

The microscopic examination revealed the presence of well-dispersed red blood cells, which are comparable with those obtained using the conventional EDTA blood anticoagulant. The observed structural change of red blood cells in blood treated with AgNPs as against the biconcave forms in EDTA-treated blood may be attributed to the nature of the biosynthesized AgNPs, particularly the concentration used and the pH level of the colloidal solution.

We are currently focusing on the optimization of these parameters to produce combinations that can prevent blood coagulation and maintain the morphology of blood cells and biochemical attributes of the blood. The essence of blood coagulation system in the maintenance of steady blood flow, the prevention of bleeding, and the prevention of the spread of infectious agents [ 52 ] by assisting the innate immune system is well established.

However, the system can also portend some troubles as the blood clots arising from infections are capable of destroying tissues, which may ultimately affects organs [ 53 ]. This can be seen in cardiovascular diseases, immunological disorders, wounds, and onset of tumor [ 54 ], [ 55 ].

Also, developed cancer cells can initiate the formation of blood clot by stimulating proinflammatory cytokines, the production of procoagulants, and the interaction with blood platelets [ 56 ], [ 57 ]. These problems have shown the necessity to control blood coagulation disorders, which can be achieved through nanotechnology. In a previous study, Shrivastava et al.

The study also established that AgNPs were not toxic to the blood platelets. Therefore, the nontoxic nature of AgNPs to platelets and its established actions against microbes can represent a paradigm shift in preventing blood coagulation. Most recently, Kim et al.

The heparin AuNPs produced aThe potential of AgNPs as a potential anticoagulant is further established in the present study.

Fruit Plants

Soil Soil for miracle fruit is a very simple mix of equal parts peat and perlite. Don't substitute perlite with vermiculite because vermiculite retains too much moisture. Pot Use plastic or peat pots only, clay pots leech clay into the soil which raises the pH. It is also not recommended to plant miracle fruit plants in the ground because it makes them more susceptible to pests. They like soils that have a pH of about 5. To attain this pH you can water them with acidic water or add suffer granules into the soil.The secret for watering is to make sure that the pH of the water and soil are both around 5. By adding an acidifier to the water of the miracle fruit plants you can lower their pH without using sulfur granules.

The Saffron Plum is not yellow or a plum, that is, it is not in the genus Prunus.And I learned it as a Bumelia , but sometime between and it became a Sideroxylon …Ya just got to love botanists and their penchants for changing plant names. Note the thorns on the Saffron Plum, Sideroxylon celastrina. In all fairness, Bumelia is not accurate for the species. Sideroxylon is better but not without issue.
