In order to investigate the effect of magnetic field on the antibacterial substances from black pepper, we used shaking and ultrasonic-assisted ethanol extraction with Escherichia coli, Staphylococcus aureus, Bacillus anthracis and Aspergillus niger as indicator bacteria respectively. Meanwhile, extraction rate and diameter of inhibition zone were regarded as the activity monitoring parameters. The results showed the existence of magnetic field can make a difference. It weakened the antibacterial activity of black pepper by shaking extraction. However, the antibacterial activity of substances to Aspergillus niger was proportional to the intensity of the applied magnetic field by ultrasonic-assisted ethanol extraction.

Abstract Leaves of selected species of the Cornaceae family (Swida alba, Swida australis, Swida controversa, Swida coreana, Swida baileyi, Cornus kousa, Cornus mas) were investigated in this study. These shrubs or small trees with hard wood are cultivated in Slovakia (Tesarske Mlyňany Arboretum). Some species (C. mas and C. kousa) have edible fruits. Cornels find broad ethnopharmacological use, for example, in Traditional Chinese Medicine (TCM), where fruits of C. officinalis are used for the treatment of several disorders, such as organ hypersecretion or diabetes. They are also used as tonics and for astringent effects. Leaves and fruits of C. kousa have been reported to possess antioxidative, anti-inflammatory and antidiabetic properties. The aim of our study is to compare the content of selected secondary metabolites groups in the leaves of above-mentioned species. The plant material was collected in the Tesarske Mlyňany Arboretum, Slovakia, in September 2010. Modified spectrophotometric methods of the European Pharmacopoeia, 8th edition (Ph. Eur. 8) were used for all assays. Results show that the total hydroxycinnamic derivatives (THD) content varied from 1.14 (S. alba) to 2.86% (S. coreana) when expressed as rosmarinic acid, and from 1.01 (S. alba) to 2.55% (S. coreana) when expressed as caffeic acid. The flavonoids content ranged from 0.21 (C. mas) to 1.37% (S. coreana), total polyphenols content from 9.6 (C. kousa) to 7.27% (S. coreana), and tannins content from 7.17 (C. kousa) to 4.04% (S. coreana). Leaves of Korean dogwood (S. coreana) were observed to show the highest content of THD expressed as rosmarinic acid (2.86%) and caffeic acid (2.55%), as well as of flavonoids (1.37%). Kousa dogwood (C. kousa) contained the highest amounts of tannins (7.17%) and total polyphenols (9.6%) on the other hand.

Phytochemical Profile

Thymus marschallianus Willd. is a Lamiaceae species spread in a large variety of habitats worldwide. The aim of the present research was to analyse two different samples belonging to this species, one obtained from the spontaneous flora and one from culture. The total polyphenols, flavonoids, and phenolic acid contents were spectrophotometrically determined. Qualitative and quantitative analysis of polyphenols was performed by an HPLC-DAD-ESI (+)-MS method. For the antibacterial assay, the well-diffusion and the broth microdilution methods were used. Analysis of polyphenols revealed for both samples the presence of flavonoids like luteolin, quercetin, apigenin and their derivatives, but also of rosmarinic acid and methyl-rosmarinate. Differences regarding the amount of these compounds were emphasized. Significantly larger amounts of flavonoids were found for the sample harvested in the spontaneous flora, while for the rosmarinic acid, larger amounts were found for the cultured sample. Both samples displayed promising antibacterial activity, particularly towards Gram positive organisms. T. marschallianus represents, therefore, a rich source of polyphenolic compounds that prove its promising potential as a medicinal species.

Consumer demand for fresh and functional horticultural products is on the rise. Perilla frutescens, L. Britt (Lamiaceae) is a potential specialty/niche crop for consumption and therapeutic uses with high contents of phenolic and volatile compounds. Plant growth, mineral composition, polyphenol profile and aroma volatile components of two perilla genotypes in response to salinity (non-salt control, 10, 20 or 30 mM NaCl) applied as chemical eustressor were assessed. Salinity suppressed growth and yield of both genotypes, although the red-pigmented genotype was less sensitive than the green-pigmented one. Mild (10 mM NaCl) and moderate (20 and 30 mM NaCl) salinity suppressed foliar potassium, magnesium, nitrate and chlorophyll a concentrations of both genotypes and increased the levels of rosmarinic acid, total polyphenols and target aroma volatile components. Green perilla showed higher yield and biomass production and higher content of protein, dry matter, calcium, magnesium, perilla ketone and cis-jasmone, whereas red perilla exhibited higher content of potassium, chlorophyll a, rosmarinic acid, total polyphenols, perilla aldehyde and benzaldehyde. Our findings support that chemical eustressors such as mild to moderate salinity offer valuable means to manipulate phytochemical and aroma profiles.

Manililla is a mango variety whose residues contain bioactive compounds such as polyphenols and flavonoids, with high added value. The use of environmentally friendly extraction technology would be of great relevance; hence, this study aimed to evaluate the effect of solvent relation, sonication time and amplitude on the ultrasound-assisted extraction of total polyphenols in Manililla mango residues (peel, endocarp and kernel) and antioxidant activity. An experimental design 23 with a central point was used to evaluate the curvature behavior of the process variables. Conventional maceration was used as a control. The better conditions were obtained at the central point using 50% ethanol in water, 60% amplitude and 20 min of sonication time. We obtained values of up to 1814 mg GAE/100 g, 469 mg GAE/100 g and 672 mg GAE/100 g of total polyphenols and 1228 mg QE/100 g, 653 mg QE/100 g and 880 mg QE/100 g of total flavonoids for peel, endocarp and kernel, respectively. Mangiferin was quantified in ultrasound-assisted extraction at 150 mg/g in peel and 0.025 mg/g in the kernel, but it was not detectable in maceration. An antioxidant capacity of 87%, 14% and 83% inhibition for peel, endocarp and kernel, respectively, were obtained. Peel and kernel were the residues with higher potential as extraction material, while endocarp was not.

Taking plateau red soil as research object, using the ultrasonic-assisted organic acid extraction the heavy metal zinc in it, and analyze the form of zinc. Results showed that the extraction rate can reach 68%, with the increase of time, the extraction effect of zinc is obviously enhanced in this method. Ultrasonic-assisted citric acid extraction soil can increase the extraction rate of exchangeable, bound to carbonates and bound to iron and manganese oxides relatively.
