“…For the genus Mimusops , different pharmacological properties have been indicated including antioxidant (Gillani & Shahwar, 2017), anti-inflammatory (Konuku et al, 2017), antimicrobial activities (Kiran Kumar et al, 2014) and hypoglycemic activity (Saradha et al, 2014). Mimusops coriacea is an important medicinal species in Ecuador; however, little is known about the morphological and anatomical characteristics of leaves, stems and seeds; as well as the molecular barcode.…”

Background Mimusops coriacea (A.DC.) Miq., (Sapotaceae), originated from Africa, were introduced to coastal areas in Ecuador where it is not extensively used as a traditional medicine to treat various human diseases. Different therapeutically uses of the species include: analgesic, antimicrobial, hypoglycemic, inflammation and pain relieve associated with bone and articulation-related diseases. Furthermore, Mimusops coriacea could be used as anti-oxidant agent. However, botanical, chemical or molecular barcode information related to this much used species is not available from Ecuador. In this study, morphological characterization was performed from leaves, stem and seeds. Furthermore, genetic characterization was performed using molecular barcodes for rbcL, matk, ITS1 and ITS2 using DNA extracted from leaves. Methods Macro-morphological description was performed on fresh leaves, stem and seeds. For anatomical evaluation, tissues were embedded in paraffin and transversal dissections were done following incubation with sodium hypochlorite and safranin for coloration and fixated later in glycerinated gelatin. DNA extraction was performed using a modified CTAB protocol from leaf tissues, while amplification by PCR was accomplished for the molecular barcodes rbcL, matK, ITS1 and ITS2. Sequence analysis was performed using blast in the GenBank. Phylogenetic analysis was performed with accessions queried in the GenBank belonging to the subfamily Sapotoideae. Results Leaf size was 13.56 ± 1.46 × 7.49 ± 0.65 cm; where is a macro-morphological description of the stem (see Methods). The peel of the seeds is dark brown. Sequence analysis revealed that amplicons were generated using the four barcodes selected. Phylogenetic analysis indicated that the barcodes rbcL and matK, were not discriminated between species within the same genus of the subfamily Sapotoideae. On the other hand, the ITS1 and ITS2 were discriminative at the level of genus and species of the Sapotoideae.

“…It has the potential to be biologically useful as an antimicrobial (bacterial and fungal), antioxidant, anticancer, wound healer, and anti-diabetic [11][12]. ZnO nanoparticles are commonly found in cosmetics [13] rubber and textiles [14][15][16] and electronics [17]. The present study revealed for synthesis and characterization of ZnO and MgO nanoparticles using geranium leaf extract.…”

The present work focus on the synthesis and structural characterization of ZnO and MgO Nanoparticles using geranium leaves extract as reducing agent through green approach. The prepared ZnO and MgO Nanoparticles were characterized using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM).The elemental composition of ZnO and MgO Nanoparticles were investigated using Energy Dispersive X-ray analysis (EDAX). Based on the XRD data, the ZnO and MgO particles were measured to be 64 and 42 nanometers in size, respectively. The DPPH method was used to further test the antioxidant property of the synthesized Nanoparticles. MgO and ZnO were both found to be excellent free radical scavengers, as measured by their DPPH scavenging activities. The antioxidant property of MgO is enhanced when compared to ZnO nanoparticles.

“…Another possibility is the surface generation of electron–hole pairs in high quantity on ZnO NPs. This process leads to the creation of hydroxyl and hydrogen radicals through water splitting through the generation of high redox potential, which finally leads to the formation of a stable DPPH molecule (Sun et al 2011 ; Kiran Kumar et al 2014 ). All these results show the synthesized ZnO NPs possess a good extent of antioxidant activity.…”

Nanostructured Zinc oxide (ZnO) materials have attained exciting research interests among various metal oxide nanoparticles due to their unique features. Thus, the scope of applications for ZnO nanoparticles (ZnO NPs) is vast and efficient. The current study demonstrates a simple and environmental-friendly approach for the synthesis of ZnO NPs using the extract of the Scoparia Dulcis . Scoparia Dulcis is a common medicinal plant in Kerala (India) that is traditionally used for its medicinal properties. Morphological characterizations of the as-synthesized ZnO NPs were evaluated using X-ray diffraction, Fourier transform infrared spectroscopy (FTIR), and field-emission scanning electron microscopy (FESEM). The results revealed that ZnO NPs showed pebble-like morphology and possessed an average particle size of ~ 20 nm. Further, antibacterial and antifungal activities of as-prepared ZnO NPs were investigated against E. coli, Staphylococcus aureus , as well as Candida albicans, and Aspergillus niger, respectively, using the agar-well diffusion method. The results revealed that the prepared ZnO NPs shows excellent antimicrobial activity against the examined microorganisms. Moreover, the antioxidant activity of the as-synthesized ZnO NPs was evaluated using the DPPH assay, which indicated an excellent IC 50 value of 1.78 μg/mL that shows high antioxidant activity. All these results proved that the S. dulcis plant extract-mediated synthesis method is a simple, low-cost, eco-friendly procedure for preparing efficient ZnO NPs for biomedical applications.
