[Analysis of phenolic acids in cultured cells and in Penstemon Serrulatus Menz].

Qualitative and quantitative content of aromatic acids in callus tissues, cells in suspension cultures and intact plants of Penstemon serrulatus was determined by paper and gas chromatography. It has been observed that these acids occur in the investigated material mainly in bounded form. The largest quantities of phenolic acids were produced by callus tissues grown on Schenk and Hildebrandt's medium. The total content of aromatic acids found in the cells from suspension cultures was similar to the content of these compounds in intact plants, but twice lower than in callus tissue grown on the same medium.
