Opis:
The interest in the properties of hydroxycinnamic acids with health-promoting properties is constantly increasing. That is why more and more research is being conducted to better understand these properties. Ferulic acid, FA (4-hydroxy-3-methoxycinnamic acid) is a derivative of hydroxycinnamic acid found in the plant tissue. It is possible to find him among others in bran cereal, popcorn bamboo shoots, and coffee. According to available literature data ferulic acid has a lot of biological properties, particularly appreciated in medicine. Its bioactive properties effectively contribute to the fight against diseases described as a civilization, including neurodegenerative diseases that increase the incidence. As reported the World Alzheimer Report, the number of people with dementia progression in 2016 exceeded 47.5 million, of which 33.5 million were diagnosed with Alzheimer's disease. According to the WHO estimates, this number will triple by 2050. The manuscript presents health-promoting properties of FA on the example of its antioxidant, antidiabetic, hepatoprotective, anti-atherosclerotic, neuroprotective, antineoplastic and antibacterial properties. In addition, the reaction of its synthesis in plants and in-vivo metabolization have been explained. The collected data suggest that bioactive FA molecules can effectively reduce the risk of civilization diseases and significantly reduce the level of oxidative stress contributing to the formation of neurodegenerative diseases.

Opis:
So far only little data have been available concerning the eliciting capacity of well defined glycan molecules isolated from plant pathogens. This study brings new information about changes in plant cells caused by fungal pathogens. Sugar fractions derived from glycoproteins isolated from the fungus Fusarium sp. M7-1 have been tested here as signaling molecules. The ability of three O-glycan fractions (named in this work inducer I, II, III) to trigger responses in Rubus protoplasts has been examined. It was found that inducer III was the most efficient as it elicited changes in the levels of phenylpropanoid pathway intermediates in relation to phenylalanine-ammonia lyase (PAL) activation.

Opis:
Natural phenolic acids are commonly present in plants consumed in the diet. Recently we have observed that different natural phenolic acids exert differential effects on the body mass gain in ovariectomized and non-ovariectomized female rats. The aim of the present study was to investigate the effects of ferulic, caffeic, p-coumaric and chlorogenic acids on serum estradiol and total cholesterol levels in ovariectomized and non-ovariectomized rats. The experiments were carried out on 3-month old female Wistar Cmd:(WI)WU rats, divided into following groups (n=8 in each group): non-ovariectomized control rats and non-ovariectomized rats receiving ferulic, caffeic, p-coumaric or chlorogenic acids, sham-operated control rats, ovariectomized control rats and ovariectomized rats receiving the same phenolic acids. The phenolic acids were administered at a dose of 10 mg/kg p.o. daily for 4 weeks. Serum estradiol and total cholesterol levels on the next day after the last administration of the phenolic acids were examined. The phenolic acids did not affect serum estradiol or total cholesterol levels in non-ovariectomized rats. In ovariectomized rats, caffeic acid and to a lesser extent p-coumaric acid increased serum estradiol level, which effect correlated with a decreased body mass gain. All the phenolic acids decreased serum cholesterol level in ovariectomized rats. Concluding, the anti-obesity activity of some phenolic acids may be, at least partially, connected with estrogenic pathways.

Opis:
We examined whether allelochemical stress leads to increased lipoxygenase activity in roots of sweet maize (Zea mays L. ssp. saccharata), pea (Pisum sativum L.) and radish (Raphanus sativum L. var. radicula). The lipoxygenase activity of soluble and membrane-bound fractions was assessed in roots after exposure to ferulic and p-coumaric acids. Lipid peroxidation and membrane injury were determined as indicators of stress. Increased lipoxygenase activity of both studied fractions was followed by lipid peroxidation and plasma membrane injury. The results suggest the key role of lipoxygenase in plasma membrane injury during allelochemical stress caused by administration of hydroxycinnamic acids.

Opis:
This paper describes the examination of raw flax fibres in terms of their antioxidant activity. Fibres originating from five varieties of flax plants cultivated in Poland: Artemida, Modran, Sara, Nike and Luna were extracted with the application of different methods: dew retting and water retting. The extraction method has an influence on the fibre chemical composition, resulting in different levels of fibre antioxidant properties. The antioxidant activity of flax fibres was evaluated with the application of ferric ion reducing antioxidant power (FRAP). The results of the study indicated differences in the bioactivity of flax fibres linked with the method of their extraction applied as well as the lignin and phenolic acid content in the fibre chemical composition.
W artykule opisano badania włókien lnianych w zakresie ich aktywności antyoksydacyjnej. Badano włókna pochodzące z pięciu odmian lnu włóknistego uprawianego w Polsce: Artemida, Modran, Sara, Nike oraz Luna, które wydobyto ze słomy z wykorzystaniem dwóch metod: roszenia wodnego oraz metody słania. W pracy wykazano związek między zastosowaną metodą roszenia, a składem chemicznym włókna oraz jego aktywnością antyoksydacyjną. Właściwości antyoksydacyjne włókna określone zostały na podstawie badania ich zdolności do redukowania jonów żelaza (Ferric Ion Reducing Antioxidant Power, FRAP). Rezultaty badań dowiodły, że poziom aktywności biologicznej włókna lnianego jest ściśle związany z zawartością lignin oraz obecnością kwasów fenolowych we włóknie, które są ściśle związane z zastosowaną metodą roszenia oraz odmianą lnu włóknistego.
