| Abstract (English): |
Epilobium species have garnered attention for their potential use in benign prostatic hyperplasia; however, their polyphenolic composition has been primarily investigated. This study aimed to perform a comparative qualitative analysis and relative comparison based on gas chromatography-mass spectrometry (GC-MS) peak area percentages of the volatile pro file in three Epilobium species growing in Estonia. The volatile profiles of E. angustifolium, E. hirsutum, and E. parviflorum were obtained by hydrodistillation. The yield of the volatile frac tion in the studied Epilobium species ranged from 0.24 to 0.78 mL/kg. Qualitative and semi-quantitative analyses of the volatile profile by GC-MS revealed the presence of 98 components, with a range of 87.12% to 92.93%. The most significant proportion of the volatile profile was made up of aliphatic hydrocarbons, 40.75%-43.09% for E. angustifolium and 34.29%-45.04% for E. hirsutum, and aliphatic acids, 15.79%-29.29% for E. angustifolium and 7.44%-22.45% for E. hirsutum. E. hirsutum also had a significant content of aldehydes and ketones, 7.08%-9.03%. Within the volatile profile, monoterpenoids in E. parviflorum accounted for 51.92%, aliphatic acids for 19.43%, and sesquiterpenes for 6.76%. Thus, aliphatic hydro carbons and fatty acids generally prevailed in E. angustifolium and E. hirsutum, while mono terpenoids predominated in E. parviflorum. Numerous volatile profiles (22-50) were identified for the first time in the investigated species. Although the yield of volatile profiles in Epilobium species is low, due to their biological activity, they may have a beneficial effect in benign prostatic hyperplasia, which requires further investigation.

| Abstract (Estonian): |
Pajulillede (Epilobium) liigid on pälvinud tähelepanu nende võimaliku kasutuse tõttu eesnäärme healoomulise suurenemise korral, kuid seni on neid uuritud peamiselt polüfenoolsete ühendite koostise seisukohast. Käesoleva töö eesmärk oli Eestis kasvavate kolme Epilobium'i liigi lenduvate ühendite kvalitatiivne ja suhtelisel sisaldusel põhinev võrdlev analüüs. Liikide E. angustifolium, E. hirsutum ja E. parviflorum lenduv fraktsioon eraldati taimede maapealsetest osadest destillatsiooni teel. Uuritud pajulilleliikide lenduvate fraktsioonide saagis jäi vahemikku 0,24-0,78 mL/kg. Lenduvate ühendite kvalitatiivne ja kvantitatiivne analüüs GC-MS-mee - todil näitas 98 komponendi esinemist, mille osakaal moodustas 87,12-92,93% destillaadist. Suurima osa lenduvast fraktsioonist moodustasid alifaatsed süsivesinikud -- E. angustifolium'is 40,75-43,09% ja E. hirsutum'is 34,29-45,04% -- ning alifaatsed happed -- E. angustifolium'is 15,79-29,29% ja E. hirsutum'is 7,44--22,45%. Lisaks iseloomustas E. hirsutum'it märkimisväärne aldehüüdide ja ketoonide sisaldus (7,08-9,03%). E. parviflorum'i lenduvas fraktsioonis domineerisid monoterpenoidid (51,92%), millele järgnesid alifaatsed happed (19,43%) ja seskviterpeenid (6,76%). Seega domineerivad E. angustifolium'i ja E. hirsutum'i lenduvas fraktsioonis peamiselt alifaatsed süsivesinikud ja rasvhapped, samas kui E. parviflorum'is on ülekaalus monoterpenoidid. Arvukalt lenduvaid ühendeid (22-50) identifitseeriti nendes taimeliikides esmakordselt. Kuigi Epilobium'i liikide lenduva fraktsiooni saagis on väike, võivad need ühendid tulenevalt oma bioloogilisest aktiivsusest kaasa aidata pajulillede toimele eesnäärme healoomulise suurenemise korral ning see teema vajab edasist uurimist.
