Opis:
Aerial parts and roots of Crithmum maritimum L. fertilized with Tytanit were investigated on the presence of phenolic acids (PhAs). Cinnamic and benzoic acid derivatives were quantified by use of validated RP-HPLC/DAD method. The amount of PhAs in fertilized plants (T) was higher than in control (C) plants (in the aerial parts: 2.16 mg/g and 1.28 mg/g dry weight, respectively, and in roots: 4.05 mg/g and 2.78 mg/g dry weight, respectively). The predominant PhA was the caffeic acid (83.2–94.2% of the total PhAs). After Tytanit treatment, amount of the caffeic acid rose from 667.41 μg/g in C to 1463.83 μg/g dry weight in the aerial parts of T, and in roots from 2251.74 μg/g in C to 3451.86 μg/g dry weight in T. Tytanit had also influence on the qualitative composition of PhAs; in extracts from aerial parts, some of PhAs (ferulic, chlorogenic, and syringic acids), absent in control, appeared after fertilization.

Opis:
Qualitative and quantitative analysis of phenolic acids present as free and liberated from their conjunction with sugars and alcohols after hydrolysis in Salsola kali L was done, together with comparison of their content in roots and herb. Analysis was conducted by 2D-TLC and HPLC methods. Eleven phenolic acids were identified such as: protocatechuic, caffeic, gentisic, p-coumaric, p-hydroxybenzoic, p-hydroxyphenylacetic, syryngic, vanillic, ferulic, α- and ß-resorcylic. Differences in composition of fraction of free phenolic acids and those liberated after hydrolysis were noticed. The amount of individual compounds were in the range between 0.10±0.04 mg/100 g of dry weight for p-OH-benzoic acid and 6.40±1.75 mg/100 g of dry weight for ferulic acid.

Opis:
The analysis of the fractions of free and bound, liberated by hydrolysis, phenolic acids in the inflorescences and rhizomes with roots of Hieracium pilosella L. was conducted by 2D-TLC and RP-HPLC methods. In the inflorescences fourteen phenolic acids were found: chlorogenic, gallic, protocatechuic, homoprotocatechuic, caffeic, gentisic, p-hydroxyphenylacetic, p-hydroxybenzoic, m-hydroxybenzoic, p-coumaric, syringic, vanillic, ferulic and salicylic. In the rhizomes with roots nine phenolic acids were identified: chlorogenic, gallic, homoprotocatechuic, caffeic, gentisic, p- hydroxyphenylacetic, p-hydroxybenzoic, syringic and vanillic. By means of the RP-HPLC method the contents of major acids were estimated which ranged from 0.01 mg% up to 139.50 mg%. Caffeic acid is the remarkably dominating constituent of both plant materials. Phenolic compounds may contribute to invasiveness and medicinal properties of this species.

Opis:
In this work the phenolic acids in the methanol extract from the flowering herbs of Cirsium vulgare (Savi) Ten. growing in Poland were isolated and identified. The samples containing free phenolic acids and those released after acid and alkaline hydrolyses were investigated by 2D TLC on cellulose. After purification by SPE, samples were also analyzed by RP-HPLC. Six phenolic acids such as gallic, protokatechuic, gentisic, hydrobenzoic, vanillic and caffeic acids were detected in the fraction of free phenolic acids of the methanol extract, irrespectively of the method used.

Opis:
In three species of Rheum L. genus growing in Poland the composition of phenolic acids was determined. By 2D-TLC method the following acids were identified: ellagic, chlorogenic, gallic, protocatechuic, homoprotocatechuic, caffeic, α-resorcilic, p-hydroxyphenylacetic, p-hydroxybenzoic, p-coumaric, syringic, vanillic and ferulic. There are no substantial qualitative differences among the complex of phenolic acids in the investigated species. The RP-HPLC method was used for quanitative determination of phenolic acids. The amount of individual phenolic acids ranged between 2.2 µg/g and 147.8 µg/g in air-dry rhizome. The content of ferulic acid is the highest in all the examined cases. The total amount of the tested phenolic acids in Rheum undulatum L., R. palmatum L., and R. raponticum L. was respectively 346.4 µg/g, 229.8 µg/g, and 195 µg/g.

Opis:
The effect of methyl jasmonate (JA-Me) and phenolic acids: trans-cinnamic acid (t-CA), p-coumaric acid (p-CA), salicylic acid (SA) as well as naringenine (NAR) on growth of seedlings and accumulation of anthocyanins in common buckwheat (Fagopyrum esculentum Moench) were studied. JA-Me and phenolics were applied to growth medium of 4-days etiolated buckwheat seedlings before their exposition to day/night (16h/8h) conditions. The increase of primary roots and hypocotyls length were measured after 3 days of seedling growth in such conditions. At the end of experiment the total anthocyanins contents were measured as well. Methyl jasmonate (JA-Me) and trans-cinnamic acid (t-CA) inhibited growth of the primary root in young buckwheat seedlings, while naringenine (NAR) had a stimulatory influence, and p-coumaric acid had no effect at all. None of investigated phenolics or JA-Me had an effect on the growth of buckwheat hypocotyls, except the mixture of JA-Me and p-coumarcic acid. JA-Me significantly decreased the anthocyanins level in buckwheat hypocototyls, but not in cotyledons. trans-Cinnamic acid, p-coumaric acid and naringenine had no significant influence on the anthocyanin level in hypocotyls and cotyledons of buckwheat seedlings. Simultaneous treatment of buckwheat seedlings with JA-Me and t-CA or p-CA did not change the inhibition of anthocyanins accumulation in buckwheat hypocotyls by JA-Me. In the hypocotyls of buckwheat treated with a mixture of JA-Me and NAR, or SA, a synergistic reduction of anthocyanins was observed.
Badano wpływ jasmonianu metylu (JA-Me) i kwasów fenolowych: trans-cynamonowego (t-CA), p-kumarowego (p-CA), salicylowego (SA) oraz naryngeniny (NAR) na wzrost siewek i akumulację antocyjanów w gryce zwyczajnej (Fagopyrum esculentum Moench). JA-Me i związki fenolowe zastosowano na 4-dniowe siewki wyrosłe w ciemności przed ich wystawieniem na warunki dnia/nocy (16h/8h). Badano także przyrost długości korzeni głównych oraz hypokotyli po 3-dniowym okresie wegetacji w takich warunkach. Wówczas też oznaczono sumaryczne zawartości antocyjanów. JA-Me i t-CA hamowały, podczas gdy NAR stymulowała wzrost korzeni głównych, zaś p-CA nie miał wpływu na ich wzrost. Badane związki fenolowe i JA-Me nie wpływały na wzrost hipokotyli siewek gryki zwyczajnej, za wyjątkiem jednocześnie zastosowanych JA-Me i kwasu p-kumarowego, które działały hamująco. JA-Me istotnie obniżał poziom antocyjanów w hipokotylach gryki, ale nie wpływał na ich zawartość w liścieniach. Kwas trans-cynamonowy, p-kumarowy i naryngenina nie miały wpływu na zawartość antocyjanów w hypokotylach i liścieniach siewek gryki. Jednoczesne zastosowanie JA-Me i t-CA lub p-CA nie wpłynęło na akumulację, podczas gdy użycie JA-Me wraz NAR lub SA spowodowało synergistyczne obniżenie zawartości antocyjanów w hipokotylach siewek gryki zwyczajnej.
