The Use of Salvia macrosiphon and Lepidium sativum Linn. Seed Gums in Nanoencapsulation Processes: Improving Antioxidant Activity of Potato Skin Extract

In the present study, the effect of Salvia macrosiphon Seed Gum (SMSG) and Lepidium sativum Linn. Seed Gum (LSSG) as a coating agent on the properties of nanoencapsulated potato skin extract was studied. Moreover, the antioxidant effect of nanoencapsulated extract at a concentration of 1000 ppm incorporated into soybean oil was evaluated. The Z-average size of the emulsions stabilized by SMSG; LSSG; and a complex (1 : 1) of SMSG and LSSG (CSL) was estimated as 160.2, 144.3, and 115.2 nm. The encapsulation efficiency of phenolic extracts in the powders formed by SMSG, LSSG, and CSL was 82.39, 81.67, and 93.6% which declined to 45.28, 48.22, and 62.67% after storage for 40 days at 30°C. The results indicated that the use of coating agents for encapsulation enhanced their antioxidant effect and compared with TBHQ and free extract that nanoencapsulated extract by CSL had the highest antioxidant activity followed by LSSG nanoencapsulated extract and SMSG nanoencapsulated extract.

In order to reduce the usage amount of pesticide fertilizers and protect the natural environment, seed coating agents are receiving increased wide concern. In this study, the active constituent (pesticide) and inactive components (surfactants and film former) of the seed coating agents were screened and optimized by the wet sand processing superfine grinding method. The fungal inhibition test of pesticides showed that thifluzamide, fludioxonil, pyraclostrobin, and difenoconazole have an obvious fungal inhibitory effect on wheat sharp eyespot, take-all, and root rot. LAE-9 and polyacrylamide + carboxymethyl cellulose (CMC) is recommended for the safe surfactant and film former, respectively, based on the seed germination test. Moreover, 6% difenoconazole · fludioxonil flowable concentrate for seed coating (FSC) stimulates the seedling growth of wheat, advances the growth of root, and improves biomass in the field trial, meanwhile, the control efficiency reached above 80%. Thus, we suggested it can be used as an effective seed coating agent for the control of soil-borne diseases in wheat. The seed coating agent has the characteristics of disease prevention, increasing crop yield, and safety of environment, which is of significance in practical application.

Phenolic Composition

The genus Cephalaria, belonging to the Caprifoliaceae family, is a rich source of interesting secondary metabolites, including mainly saponins which display a variety of biological activities, such as immunomodulatory, antimicrobial and hemolytic effects. Besides these compounds, flavonoids and phenolic acids were identified in Cephalaria species. Cephalaria is employed in traditional medicine e.g., to cure cardiac and lung diseases, rheumatism, and regulate menstruation. In this review we focus on the phenolic compound composition and antioxidative activity of Cephalaria species. The antioxidant effect can be explained by flavonoids present in all parts of these plants. However, future efforts should concentrate more on in vitro and in vivo studies and also on clinical trials in order to confirm the possibility of using these plants as natural antioxidants for the pharmacology, food or cosmetic industries.

Peel Extract

Cocoa pod extract ((Theobroma cacao L.) has antioxidant and antimicrobial activity that has the potential as a natural food preservative. However, in its use the cocoa fruit skin extract has a disadvantage because the short shelf time and its application to food are limited, efforts are needed to prevent damage and extend shelf life, one of the efforts that can be done is by encapsulating the extract.This study aims to determine the antibacterial activity and antioxidant encapsulation of cocoa peel extract, this study begins with the extraction of cocoa pods with ethanol solvent by comparing cocoa pods : solvent 1: 4 The skin of cacao cocoa fruit used is yellow harvested cocoa fruit, then chopped and dried to form flour.The sample is extracted by maceration with ethanol solvent Antioxidant test is done by DPPH method, while antibacterial test is carried out by the well diffusion method. This study used a completely randomized design method (CRD) with 5 treatments using a maltodextrin concentration of 20% (M1); 30% (M2); 40% (M3); 50% (M4) and 60% (M5). The results showed that the treatment gave the highest yield in the treatment of 60% maltodextrin concentration (M5), while the highest antioxidant activity was obtained in the treatment of 20% maltodextrin (M1) with IC50 75.98 µg / mL and the treatment with the lowest antioxidant activity was obtained at treatment of 60% maltodextrin concentration (M5) with IC50 value 114.89 µg / mL. While for the antimicrobial activity also obtained with the same results, namely treatment of 20% (M1) obtained a higher inhibition diameter compared to treatment at 30%; 40%; 50% and 60% for all types of bacteria. The inhibition diameter in the treatment of the concentration of maltodextrin 20% (M1) for E. coli bacteria is between 4.12 mm - 10.95 mm, Salmonella sp is 2.85 mm - 8 , 25 mm and for Staphylococcusaureus of 5.15 mm - 13.90 mm and the lowest inhibition diameter was obtained in the treatment of 60% maltodextrin concentration (M5) for E. coli bacteria of between 2.0 mm - 4.79 mm, Salmonella sp of 1.15 mm - 4.35 mm and for Staphylococcusaureusat 2.76 mm - 5.17 mm.This study concluded that the encapsulation of cocoa peel extract using 20% maltodextrin had the highest antioxidant and antimicrobial activity when compared with other treatments namely 30% concentration; 40%; 50% and 60% but for the treatment of 20% and 30% there is no difference. Ethanol extract of cocoa pods can be made in the form of encapsulates which are very likely to be used as natural preservatives.

Coating Agents

In recent years, the intrinsic magnetic properties of magnetic nanoparticles (MNPs) have made them one of the most promising candidates for magnetic resonance imaging (MRI). This study aims to evaluate the effect of different coating agents (with and without targeting agents) on the magnetic property of MNPs. In detail, iron oxide nanoparticles (IONPs) were prepared by the polyol method. The nanoparticles were then divided into two groups, one of which was coated with silica (SiO2) and hyperbranched polyglycerol (HPG) (SPION@SiO2@HPG); the other was covered by HPG alone (SPION@HPG). In the following section, folic acid (FA), as a targeting agent, was attached on the surface of nanoparticles. Physicochemical properties of nanostructures were characterized using Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), and a vibrating sample magnetometer (VSM). TEM results showed that SPION@HPG was monodispersed with the average size of about 20 nm, while SPION@SiO2@HPG had a size of about 25 nm. Moreover, HPG coated nanoparticles had much lower magnetic saturation than the silica coated ones. The MR signal intensity of the nanostructures showed a relation between increasing the nanoparticle concentrations inside the MCF-7 cells and decreasing the signal related to the T2 relaxation time. The comparison of coating showed that SPION@SiO2@HPG (with/without a targeting agent) had significantly higher r2 value in comparison to Fe3O4@HPG. Based on the results of this study, the Fe3O4@SiO2@HPG-FA nanoparticles have shown the best magnetic properties, and can be considered promising contrast agents for magnetic resonance imaging applications.

Atractylodes Macrocephala

The Atractylodes macrocephala polysaccharide (AMP) was extracted by water extracting-alcohol precipitating method and further purified by DEAE column. After that, the polysaccharides were modified by nitric acid-sodium selenite method, and nine kinds of selenizing AMPs (sAMPs) were obtained, namely, from sAMP1 to sAMP9. AMP and sAMP were characterized using FTIR spectrometry. Then their antioxidant activities in vitro were measured by free radical-scavenging test. Among these, sAMP6 presented the strongest antioxidant effect. For the test in vivo, the chickens at day 14 vaccinated with ND vaccine were repeatedly vaccinated at day 28. The chickens in sAMP and AMP were injected respectively with 1 mg of sAMP6 and AMP and, in vaccination control (VC) and BC groups, injected with equal volume of normal saline. Respectively, after the first vaccine, on days 7, 14, 21, and 28, the serum GSH-Px and SOD activities and MDA content were determined. The results suggested that sAMP6 could significantly promote GSH-Px and SOD activities and decrease MDA content. All these results indicated that selenylation modification could significantly enhance the antioxidant activity of AMP.
