“…In in vitro cultures of this plant species, higher amounts of catechin, epicatechin, and epicatechin gallate have been estimated in in vitro cultivated biomass than in tested comparative plant material [22]. Additionally, Fagopyrum esculentum and Quercus acutissima in vitro cultures are also indicated as rich sources of different catechins [23,24].…”

In vitro cultures of Cistus ×incanus (pink rock-rose) were maintained on two variants of Murashige and Skoog (MS) medium differing in terms of composition of plant growth regulators (PGRs): 6-benzyl adenine (BA) and 1-naphthaleneacetic acid (NAA) at the following concentrations: 3 mg/L and 0, 3 mg/L and 1 mg/L, respectively, and on a variant without PGRs -a control. Cultures were maintained in a form of agar and agitated shoot cultures. The qualitative and quantitative analyzes of three groups of phenolic compounds (catechins, flavonoids, and free phenolic acids) were performed by using the HPLC-DAD technique in methanolic extracts of in vitro biomasses and of commercial plant raw material. In analyzed extracts from in vitro cultures, the presence of catechin [max. 197.80 mg / 100 g dry weight (DW)], epicatechin gallate (max. 30.74 mg / 100 g DW), gallic acid (max. 83.23 mg / 100 g DW), quercetin (max. 10.15 mg / 100 g DW), and quercitrin (max. 72.89 mg / 100 g DW) was confirmed. The quantities of accumulated compounds varied and depended on the type of in vitro culture and the concentration of PGRs in media. The highest amounts of all estimated compounds were obtained in biomasses from agar cultures cultivated on medium without PGRs in vitro. In extracts obtained from commercial raw material, gallic acid (max. 261.80 mg / 100 g DW) and quercetin (max. 255.96 mg / 100 g DW) were detected as being the dominant compounds.

“…However, content analysis showed that rutin and o-coumaric acid were two-fold higher in Coker 312, and catechin, caffeic acid, ferulic acid and salicylic acid were threefold higher (Table III). This suggests that the amounts of certain phenolic compounds play a significant role in the induction of callogenesis, as mentioned by others (Hoffmann et al, 1985;Moumou et al, 1992;Baaziz et al, 1994;El Hadrami & Baaziz, 1995;Karimdzhanov et al, 1997;Luczkiewicz & Glod, 2003;El Bellaj & El Hadrami, 1998;Kouakou et al, 2004a, b). The high amounts of rutin, catechin, o-coumaric acid, caffeic acid, ferulic acid and salicylic acid could be considered as indicators of efficient callogenesis, which could evolve into the induction of embryogenic structures.…”

“…However, the possible roles of these compounds during the induction of callogenesis has been examined only in a few plants such as Crataegus monogyna, Fagopyrum esculentum, Fragaria xananassa, Medicago sativa and Phoenix dactylifera (Moumou et al, 1992;Ishimaru et al, 1993;Bahorun et al, 1994;Baaziz et al, 1994;Lozovaya et al, 1996). In cotton, we previously found that metabolites produced during callus cultures were different between Coker 312, an embryogenic cultivar, and ISA 205N, which is not (Kouakou, 2003).…”

Abstract.-We study the production of polyphenols by callus cultures from two cultivars of cotton (Gossypium hirsutum L.). Coker 312 produces the best calli and has embryogenic potential contrary to that of R405-2000, which is nonembryogenic. There is a relationship between the level of phenolic compounds and the callus cultures. Callogenesis in Coker 312 is highly correlated to a higher content of catechin, caffeic acid, ferulic acid, rutin, o-coumaric acid and salicylic acid. On the other hand, the cinnamic acid derivates (trans-cinnamic, cis and trans-methoxycinnamic acids) found in high amounts in R405-2000 calli could have a negative influence on the induction of cotton callogenesis. Key wordsRésumé.-Nous avons étudié la production en polyphénols de cultures en cal de deux variétés de cotonnier (Gossypium hirsutum L.). La variété Coker 312 produit les meilleurs cals et possède des potentialités embryogènes, contrairement à la variété R405-200 qui est non embryogène. Nous avons mis en évi-dence une relation entre les teneurs en composés polyphénoliques et les cals cultivés. La callogénèse chez Coker 312 est fortement corrélée avec une plus forte teneur en catéchine, acide caféique, acide ferulique, rutine, acide orthocoumarique et acide salicylique. Par contre, les dérivés de l'acide cinnamique (acides trans-cinnamique, cis and trans-methoxycinnamique), présents en grande quantité dans les cals de R405-2000, pourraient avoir une influence négative sur l'induction de la callogénèse chez le cotonnier.
