Effect of ecological factors on the accumulation of phenolic compounds in Iris species from Latvia, Lithuania and Ukraine.

Introduction: It is important to conduct studies on the influence of environmental factors on the accumulation of secondary metabolites in plants, as well as the cultivation of plants and harvesting of their raw material.

Objective: In this study, we examined the influence of habitat types, soil composition, climatic factors and altitude on the content of phenolic compounds in Iris species from different populations in Latvia, Lithuania and Ukraine.

Methodology: According to high-performance liquid chromatography (HPLC) analysis, 25 compounds (flavonoids, isoflavonoids, isoflavonoid glucosides, xanthones, phenolcarboxylic acids) were identified in the methanol extracts of 16 samples of Iris rhizomes.

Biologically active compounds and pharmacological activities of species of the genus Crocus: A review.

The present article is the first comprehensive review on the chemical composition and pharmacological activities of the raw materials of Crocus species. In the present review, data on chemical constituents and pharmacological profile of Crocus sativus stigmas, as well as of other plant parts (perianth, stamens, leaves, corms) of different Crocus spp. are given.
