THE TREATMENT OF GALII HERBA WITH FASCICLES OF IONIZING RADIATIONS AND ITS INFLUENCE ON SOME SECONDARY METABOLITES, THERAPEUTICALLY IMPORTANT
Journal Title: Analele Stiintifice ale Universitatii Alexandru Ioan Cuza din Iasi, Serie noua, Sectiunea II a. Biologie vegetala - Year 2009, Vol 55, Issue 1
Abstract
The aim of the paper is to evaluate the influence on the Galii herba product of some irradiation doses (accelerated electron fascicles) used for its microbial decontamination. The vegetal material constituted by the control and 9 samples of the same raw material was treated with irradiation doses between 0.001-5.0 kGy in the Laboratory of Accelerated Electrons from INFLRP-Magurele Bucuresti. The phytochemical determinations were achieved on a methanol exhaust prepared from Galii herba, irradiated and non-irradiated, using TLC, HPLC and spectrophotometric determinations. We quantitatively and qualitatively evaluated the content of flavonoids, polyphenolic acids, iridoids triterpens of the phytosterolic type and pentacyclic triterpenic acids. Applying a decontamination treatment with up to 2.5 kGy does not substantially diminish the content of active principles of the analyzed vegetal material.
