Determination of free and bound phenolic acids in leaves and fruitsof Pyracantha coccinea (L.) Roem. (Rosaceae)
Abstract
The analysis of the fractions of free and liberated by hydrolysis phenolic acids in the fruits and the leaves of Pyracantha coccinea was conducted by TLC and RP-HPLC methods. In the fruits eight and in the leaves thirteen phenolic acids were identified. By means of the RP-HPLC method the content of major acids was estimated, which ranges from 0.002 up to 17.38 mg/100 g of the dry material. Protocatechuic acid is a remarkably dominating constituent of both plant materials.
