The aim of the present work was to recognize the reasons for differences in the photodynamic action of dyes against various bacterial strains. It is expected that a better understanding of this problem may help in design of new photosen-sitizers. The sensitivity of 6 various bacterial strains to the photodynamic action of 5 photosensitizers was determined. The hydrophobicity of cell surface and susceptibility of bacteria to the natural defense mechanism of human serum, were estimated. The differences in the photodynamic efficiency of dyes could be contributed to various affinities of cell membrane to dyes, to known details of membrane architecture as well as to different mechanisms of photosensitization.

Eight accessions of St. John's wort (Hypericum perforatum L.) originating from natural sites in Lithuania were investigated ex situ. The content and composition of flavonoids and phenolic acids, as well as the contents of hypericin and pseudohypericin in the herb were determined. The total contents of flavonoids and phenolic acids ranged from 2.42% to 3.10% and from 1.16% to 3.17%, respectively. The dominant flavonoid compounds were rutin, hyperoside and isorhamnetin-3-rutinoside. The presence of two phenolic acids (chlo- rogenic and 4-hydroxyphenylacetic one) was also stated. The content of hypericin and pseudohypericin ranged from 37.01 to 99.12 mg/100g.
