Phenolic compounds in strawberry (Fragaria x ananassa Duch.) microshoots

Abstract

The HPLC method was used to study the composition and contents of phenolic compounds in the microshoots of Fragaria × ananassa Duch. plantlets during the multiplication and in vitro rooting stages in comparison with field-grown plants. Phenolic compounds of the microshoots are predominantly represented by ellagic acid and its derivatives, as well as hydroxycinnamic and hydroxybenzoic acids, in contrast to the leaves of field-grown plants with a high level of flavonoids. The increased contents of individual hydroxybenzoic and hydroxycinnamic acids in the microshoots compared with the leaves of field-grown strawberry plants indicates a possible role of phenolic acids in plant adaptation under in vitro conditions.

Transformation of Strawberry Plants’ Phenolic Profile after Treatment with a Mechanocomposite Based on Silicon Chelates in the Course of Development under In Vitro, Ex Vitro, and In Vivo Conditions

“…In strawberry leaves, phenolic compounds from several classes have been identified: hydroxybenzoic and hydroxycinnamic acids, ellagic acid derivatives (including ellagitannins), catechins, and flavonols [20,21]. Previously, we investigated the phenolic profile of strawberry leaves and its changes throughout plant development in tissue culture, including under the influence of a silicon-based biostimulant; we revealed upregulation of some phenolic acids and ellagic acid derivatives [22,23].…”
