“…Those results are in agreement with the highest values of total phenolic compounds (obtained after chromatographic analysis of individual compounds) also found for this sample in the present study. Until now there was no information about phenolic composition of coriander fruits and in vitro samples, although there are a few reports on coriander leaves from Brazil (Meloa et al, 2005), Denmark (Justesen & Knuthsen, 2001) and India (Nambiar et al, 2010), but the authors used different methodologies of extraction and detection, which do not allow a proper comparison of the results. Coriander leaves from India (Nambiar et al, 2010) seemed to be a rich source in quercetin, and the Danish sample (Justesen & Knuthsen, 2001) only presented this compound.…”

Phenolic profiles of in vivo and in vitro grown Coriandrum sativum L.

Coriandrum sativum L. is a source of a variety of polyphenols and other phytochemicals, related to its high antioxidant activity and to its use for indigestion, rheumatism, and prevention of lipid peroxidation damage. Plant cell cultures are a means to study or to produce some active metabolites such as polyphenols. This technique was applied to the investigation of coriander, and a detailed analysis of individual polyphenols in vivo and in vitro grown samples was performed. The in vivo vegetative parts showed quercetin derivatives as the main flavonoids and quercetin-3-Orutinoside (3296 mg/kg dw) was the main polyphenol found in this part of coriander.The fruits revealed only phenolic acids and derivatives, being caffeoyl N-tryptophan hexoside (45.33 mg/kg dw) the most abundant phenolic derivative. In vitro samples also gave a high diversity of polyphenols, being C-glycosylated apigenin (2983 mg/kg dw) the main compound. Anthocyanins were only found in clone A, which was certainly related to its purple pigmentation, and peonidin-3-O-feruloylglucoside-5-O-glucoside was the major anthocyanin found (1.70 µg/kg dw). In vitro culture can be used to explore new industrial, pharmaceutical and medicinal potentialities, such as the production of secondary metabolites like flavonoids.

“…Furthermore, according to different authors, this species is also a source of a variety of phenolic compounds (Justesen & Knuthsen, 2001;Meloa, Filho, & Guerra, 2005;Nambiar, Daniel, & Guin, 2010). In a previous study we compared the antioxidant potential of in vivo and in vitro grown coriander (Dias et al, 2011).…”

“…The extraction of quercetin and chlorogenic acid from bilberry was adapted from the work done by Justesen and Knuthsen (2001), but with some modification. 5 g fresh material put into 50 mL tubes, pour 10 mL 2M HCl in 50 % methanol, 10 min.…”

The bioactive substances such as total polyphenols, anthocyanins, quercetin, chlorogen acid, pterostilbene and antioxidant activity in samples of bilberry (Vaccinium myrtillus L.) from different natural localities of the Slovak Republic -Oščadnica and Liesek (northwestern Slovakia), Poprad, Kežmarok, Stará Ľubovňa (northeastern Slovakia) and one sample of blueberry (Vaccinium corymbosum L.) from local supermarket was determined. The total of polyphenols ranged from 33772.5 ± 737.99 mg*kg -1 dw (Kežmarok) to 9685.0 ± 958.63 mg*kg -1 dw (supermarket). The content of total antocyanins was detected in a range from 5578.0 mg*kg -1 dw in a sample from the supermarket to 2887.75 mg*kg -1 dw from Kežmarok locality. The highest quercetin content was detected in the sample from Liesek locality (6.79 ± 0.36 mg*kg -1 dw), then in Stará Ľubovňa (6.03 ± 0.31 mg*kg dw. Higher amounts were detected in samples harvested from Poprad locality and the order follows: Poprad > Kežmarok > Stará Ľubovňa > Oščadnica > supermarket > Liesek. The content of pterostilben varied between 2.162 ± 0.217 mg*g -1 dw in the sample from the supermarket and 1.274 ± 0.312 mg*g -1 dw in the sample from Stará Ľubovňa. The highest values of antiradical activity were found in the sample from Kežmarok (81.180 ± 2.020 % inhibition). Based on these measures a conclusion is that geographical location of bilberry harvest was functional in relation to levels of bioactive substances, plus other factors such as weather, ripeness and harvest technique may have a contributory role. From these results, it can be determined, that bilberry contains a significant 1210Journal of Central European Agriculture, 2013, 14(3), p.1210-1219 DOI: 10.5513/JCEA01/14.3.1328 volume of bioactive substances -highly effective during preventive and supportive therapy of chronic diseases such as cardiovascular diseases, hypercholesterolemia, diabetes mellitus and others.Keywords: antioxidant activity, anthocyanins, bilberry (Vaccinium myrtillus L.), chlorogen acid, locality, pterostilbene, quercetin, Slovak Republic, total polyphenols Abstrakt Práca prináša výsledky hodnotenia antioxidačnej aktivity a obsahu bioaktívnych látok ako sú celkové polyfenoly, antokyaníny, kyselina chlorogénová, quercetin a pterostilben vo vzorkách čučoriedky obyčajnej (Vaccinium myrtillus L.). Hodnotené vzorky boli zhromaždené z vybraných prírodných lokalít severného Slovenska (Oščadnica, Liesek, Poprad, Kežmarok a Stará Ľubovňa), jedna vzorka bola z ponuky miestnych supermarketov, krajina pôvodu Uruguaj. Na základe získaných meraní a výsledkov možno konštatovať, že na obsah bioaktívnych látok mala vplyv lokalita pôvodu (rastu) čučoriedky, pričom sa prejavil aj vplyv ďalších faktorov ako sú poveternostné podmienky, stupeň zrelosti a spôsob zberu plodov. Získané výsledky možno interpretovať ako potvrdenie toho, že čučoriedky obsahujú významné množstvo bioaktívnych látok, ktorých vplyv možno hodnotiť ako vysoko efektívny v prevencii a tiež aj v podpornej liečbe chronických ochorení neinfekčného pôvodu,...
