“…The low value Abs 440 /Abs max for peaks 1 and 3 (Table 2) suggests that the attachment of the sugar was at the same time in positions C-3 and C-5. For comparison, in the tests conducted by Mikanagi et al [29] in the taxa of section Rosa, the ratio of Abs 440 /Abs max was for the peonidin 3-O-glucoside, peonidin 3,5-di-O-glucoside, and cyanidin 3,5-di-O-glucoside, respectively, 28, 13, and 16%.…”

Rosa rugosa petals are a rich source of phenolic compounds, which determined their antioxidant properties. The aim of this study was to determine the polyphenolic composition of not processed petals of Rosa rugosa collected from the commodity crops and to determine the variability of the contained therein polyphenols between harvesting seasons. Twenty polyphenols were identified by UPLC-ESI-MS. The main fraction of polyphenols was ellagitannins, which are 69 to 74% of the total polyphenols of the petals. In the petals of Rosa rugosa, four anthocyanins have been identified: cyanidin 3,5-di-O-glucoside, peonidin 3-O-sophoroside, peonidin 3,5-di-O-glucoside, and peonidin 3-O-glucoside, of which the predominant peonidin 3,5-di-O-glucoside represented approx. 85% of all the determined anthocyanin compounds. It was found that the petals of Rosa rugosa are a valuable source of bioactive compounds and can be considered as a healthy valuable resource.

The oil content and fatty acids profile of a number of Polish wild species of rose fruits were examined by GC. The total fatty acid contents ranged from 6.5% to 12.9% of dry mass in fruits. The composition of oils was similar in the investigated species.17 components were identified. An average composition was estimated as follows: linoleic acid (44.4-55.7%), =-linolenic acid (18.6-31.4%), oleic acid (13.5-20.3%), palmitic acid (2.3-3.3%), stearic acid (1-2.5%), octadecenoic acid (0.38-0.72%), eicosenoic acid (0.3-0.7%), eicosadienoic acid (0-0.16%), erucic acid (0.03-0.17%) and minor fatty acids.The results indicate that rose fruits are a rich source of unsaturated fatty acids, especially in R. rubiginosa, R. rugosa and R. dumalis.There were statistically significant (p<0.05) differences in fatty acid compositions of some species. Fatty acids were suggested to have a potential chemotaxonomic value in this genus.KEY WORDS: Fatty acids composition, Rosa L. fruits, GC analysis. MATERIAL AND METHODS Plant materialRose hips were collected from bushes widely growing in Kazimierz Dolny near Lublin in Poland in September 2002 and authenticated by Prof. Dr T. Krzaczek. Names of species are those by Zieliñski (1985Zieliñski ( , 1987 and varieties by Popek (1996). A voucher specimens have been deposited in the herbarium of Department of Pharmaceutical Botany, Medical University, in Lublin. The examined species are given in Table 1. 230 Nowak R.

“…Roses, carnations, and chrysanthemums account for half of the cut flower market, and they are economically important floricultural crops. Although there has been intensive hybridization breeding to increase flower color varieties, which are based on anthocyanidins, roses (Mikanagi et al 2000;Mikanagi et al 1995) and carnations (Nakayama et al 2000) can only produce those derived from pelargonidin and cyanidin, while chrysanthemums produce cyanidin based anthocyanins (Nakayama et al 1997) but not delphinidin, while they rarely accumulate methylated anthocyanins. The expression of the flavonoid 3′,5′-hydroxylase (F3′5′H) gene (Figure 1) in these crops successfully generated delphinidin in the petals and novel flowers with blue hues were obtained, which is not possible by hybridization breeding (Tanaka and Brugliera 2013;Tanaka and Brugliera 2014).…”

We isolated a cDNA encoding S-adenosylmethionine: anthocyanin 3′,5′-O-methyltransferase (A3′5′OMT) from a cDNA library derived from Torenia hybrida petals that mainly accumulated malvidin type anthocyanins using the petunia A3′OMT cDNA as a probe. The torenia A3′5′OMT shared 52-72% amino acid sequence identity with previously reported AOMTs and belongs to the Group A1 methyltransferase family that also include caffeoyl CoA O-methyltransferase. The recombinant A3′5′OMT produced by Escherichia coli efficiently catalyzed methylation of the 3-glucoside and 3,5-diglucoside of delphinidin and cyanidin, but it did not catalyze the methylation of anthocyanidins, flavonols, or flavones. The torenia A3′5′OMT gene was expressed in Nierembergia sp., the petals of which naturally accumulate anthocyanins derived from delphinidin. The resultant transgenic petals produced methylated anthocyanins, based on malvidin and petunidin, in addition to delphinidin, which indicated that the torenia A3′5′OMT gene was functional in a heterologous plant. Rose petals rarely contain methylated anthocyanins. Transgenic rose petals expressing both a pansy flavonoid 3′,5′-hydroxylase (F3′5′H) and the torenia A3′5′OMT genes accumulated methylated anthocyanins based upon malvidin, petunidin, and peonidin, which comprised up to 88% of the total anthocyanidins, and their magenta color was more brilliant than that of the petals that accumulated delphinidin type anthocyanins by expressing the F3′5′H gene alone. These results indicate that the torenia A3′5′OMT gene is a useful molecular tool for altering and diversifying flower color.
