Phenolic acids in Crithmum maritimum L. (Apiaceae) after Tytanit fertilization

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.
