Opis:: Dokonano przeglądu potencjalnego wpływu wybranych składników żywności na aktywność umysłową oraz ryzyko wystąpienia dysforii, demencji i depresji. Przedstawiono dowody na kluczową rolę m.in. witamin z grupy B i witamin przeciwutleniających w ochronie przed niekorzystnymi zmianami w naczyniach krwionośnych, aterosklerozą i demencją. Wskazano równie na udział choliny, alkoholu i kofeiny w funkcjonowaniu centralnego układu nerwowego oraz diety na syntezę neuroaktywnego składnika – β-endorfiny.
In the paper presented, the authors review the potential impact of selected nutrients on mental activity, as well as the risk of dysphoria, dementia, and depression to occur in people. Evidence was provided that the B-complex and antioxidant vitamins play an important role in the protection against unfavorable changes in blood-vessels, as well as against arteriosclerosis and dementia diseases. It was demonstrated that such substances as choline, alcohol, and caffeine are significantly involved in the functioning of the central nerve system, and that a diet influences the synthesis of ß-endorphin, which is a neuro-active substance.

Opis:: Processing tomato production represents an important part of the total production of processed vegetables in the world. The quality characteristics of processing tomato, important for the food industry, are soluble solids content and antioxidant content (such as lycopene and polyphenols) of the fruit. Analytical quantification of these components is destructive, time and labour consuming. That is why researchers try to develop a non-destructive and rapid method to assess those quality parameters. The present study reports the suitability of a portable handheld visible near infrared spectrometer to predict soluble solids, lycopene and polyphenol content of tomato fruit puree. Spectral ranges of 500-1000 nm were directly acquired on fruit puree of five different tomato varieties using a FieldSpec HandHeld 2™ Portable Spectroradiometer. Immediately after spectral measurement, each fruit sample was analysed to determine soluble solids, lycopene and polyphenol content. Partial least square regressions were carried out to create models of prediction between spectral data and the values obtained from the analytical results. The accuracy of the predictions was analysed according to the coefficient of determination value (R2), the root mean square error of calibration/cross-validation.

Opis:: Toxicity and physiological alterations were determined in Pseudococcus viburni nymphs treated with Artemisia annua methanolic extract. The leaf dipping bioassay showed LC50 values of 0.287% and 0.194% 24 and 48 hours post-exposure. Activities of general esterases were significantly higher in the control nymphs than in those which had been treated except for the 48 h time interval using α-naphtyl acetate. The activity of glutathione S-transferase using CDNB (1-chloro-2,4-dinitrobenzene) in the control nymphs, was significantly higher than in the control at both time intervals while no significant difference was observed after 24 h in addition to the higher enzymatic activity in the treated nymphs after 48 h. All three aminotransferases were significantly more active in the control nymphs except for time intervals of 24 h for γ-glutamyl transferase and 48 h for alanine aminotransferase. Higher activities of lactate dehydrogenase, acid- and alkaline phosphatase were found in the control nymphs than in treated nymphs for all time intervals. Activities of the enzymes involved in the antioxidant system including catalase, peroxidase, superoxide dismutase, ascorbate peroxidase and glucose-6-phosphate dehydrogenase was increased in the treated nymphs compared to the control. Results of the current study demonstrated toxic effects of A. annua methanolic extract on P. viburni nymphs causing mortality and physiological turbulences.

Opis:: Introduction: In order to prevent increased bacterial resistance, it is important to use herbal medicines with less side effects. Objective: In this study, the chemical composition, antimicrobial, antioxidant activities and SEM images of Lavandula officinalis and Origanum onites oils obtained in two different ways were determined. Methods: The antimicrobial activity of the oils was determined against reference and multiple strains of foodborne and pathogenic bacteria. The each essential oil sample were analyzed by GC–MS. Antioxidant activities of the samples were examined through DPPH• and ABTS•+ radical scavenging and FRAP assays. Results: The results indicate that the oils of obtained from Origanum onites and Lavandula officinalis exhibited relatively strong antibacterial and antifungal activity. In addition, the antioxidant activities detected were remarkable. Morphological changes in bacterial cells treated with essential oil samples were demonstrated with SEM images. In addition, the chemical components of the oil samples obtained by both water steam and cold press were revealed by GC-MS analysis and compared. Conclusion: When all the obtained results are evaluated together; these plants could be suitable for using as antimicrobial and antioxidative agents in several industries such as food, cosmetic, etc.

Opis:: In Poland, the genus Rubus comprises 95 species. Given the commercial production of the fruits as well as their medicinal properties and apicultural and ornamental importance, raspberries are commonly cultivated plants of great economic value. Rubi idaei folium exhibits a wide spectrum of pharmacological activities. The aim of the present study was to determine the content of some bioactive compounds and compare the antioxidant activity in R. ideaus leaves. The highest and lowest content of chlorophyll was found in the ‘Laszka’ and ‘Glen Ample’ varieties, respectively. The content of total fat, carbohydrate, and total protein was 2.1%, 6.2%, and 20%, respectively. Saturated fatty acids were dominated by palmitic, arachidonic, tetracosanoic, and stearic acids. Omega 3, omega 6, and omega 9 acids were mainly represented by α-linolenic acid, linolenic acid, and oleic acid, respectively. The highest antioxidant activity was determined in the leaves of the ‘Radziejowa’ variety, and the lowest level was found for the ‘Glen Ample’ variety. The high antioxidant activity and the content of bioactive compounds indicate that raspberry leaves can be used as drinkable infusions or extracts applied as additives to some food products.
