The plants of angelica Archangelica officinalis may be colonized by various species of fungi including Phoma species. The paper concerns the fungus Phoma complanata, isolated from above-ground and underground parts of angelica in 2009–2011. Pathogenicity tests according to Koch’s postulates were carried out on angelica plants using various methods of inoculation. Observations of the infection process were made using the scanning electron microscope (SEM). Three our own isoletes and reference isolate of P. complanata were used in the study. P. complanata was found to be a facultative pathogen of angelica, which enters to the plant through stomata and wounds without creating appressoria in the top part of the germination hyphae.

The aim of this work was the analysis of essential oil from fruits of Archangelica officinalis received from Central Station of Seed Production in Bydgoszcz, and essential oil compounds occurring in fruits extracts. Essential oil was obtained as a result of steam water distillation and solvent extraction was done with hexane and methylene chloride. Analysis of essential oil compounds was done by using GC/MS method. The major components of essential oil are monocyclic terpenes (a- and ß-phellandrene, a-pinene and p-cymene) and sesquiterpenes (a-humulene, germacrene D, a-zingiberene, ß-farnezene). The most important compound of extracts from angelica fruits is ß-phellandrene. The percentage content of ß-phellandrene in essential oil fraction occurring in hexane extract was 64.3%, and in methylene chloride extract 38.0%. The aim of this work was also chromatographic analysis of fatty acids. GC analysis showed, that the major compound was oleic acid (18:1).
