Significant seasonal differences were found in the amounts of lichen secondary metabolites analysed by HPTLC and HPLC-PDA between summer and winter collected thalli in sandy grassland area in Hungary. The concentrations of usnic acid varied between 7.34 and 15.52 mg/g in summer collected samples and 13.90 and 21.61 mg/g in winter collected ones. A comparable amount (11.61±0.29 mg/g) was measured in pulverised samples. The concentrations of fumarprotocetraric acid varied between 0.60 and 3.01 mg/g in summer collected samples and 2.26 and 5.81 mg/g in winter collected thalli. A comparable amount (2.45±0.21 mg/g) was found in pulverised samples. The range of concentration values is comparable with data known from lichens. A higher amount of usnic acid is produced in winter probably to ensure sufficient protection also for summer. The fumarprotocetraric acid content of the medulla might contribute to the solar irradiation reflecting role of the pale lower surface lobes turning upwards in dry condition. true true 2020 false true true false true false GOLD 2025-11-13 true https://doi.org/10.1556/034.62.2020.1-2.4 18 0 18 11 5 17 18 16 17 18 18 11 11 11 7 0 18 11 18 11 0 7 7 Folyóiratcikk Journal Article 24 17 Könyvrészlet Chapter in Book 25 1 Könyv Book 23 0 Egyéb konferenciaközlemény Conference paper 31 0 Egyéb konferenciakötet Conference proceedings 32 0 Oltalmi formák Protection forms 26 0 Disszertáció Thesis 28 0 Egyéb Miscellaneous 29 0 Alkotás Achievement 22 0 Kutatási adat Research data 33 0 Folyóiratcikk Journal Article 24 0 0 0 Könyvrészlet Chapter in Book 25 0 0 0 Könyv Book 23 0 0 0 Egyéb konferenciaközlemény Conference paper 31 0 0 0 Egyéb konferenciakötet Conference proceedings 32 0 0 0 Oltalmi formák Protection forms 26 0 0 0 Disszertáció Thesis 28 0 0 0 Egyéb Miscellaneous 29 0 0 0 Alkotás Achievement 22 0 0 0 Kutatási adat Research data 33 0 0 0 2020 0 1 0 1 0 2021 0 5 4 5 4 2022 0 4 2 4 2 2023 0 4 4 4 4 2024 0 3 0 3 0 2025 0 1 1 1 1 Q2 A false 10003979 false false false 2020-08-03T06:32:11.767+0000 Acta Botanica Hungarica szerkesztősége (Kiadók / MTA KFB); Ökológiai és Botanikai Intézet (HUN-REN ÖK) 5 29 2 6 0 false Language 10002 /api/language/10002 Angol English true 2 true PersonAuthorship 92247922 /api/authorship/92247922 1 0.16666667 true false false Author 10003979 /api/author/10003979 Farkas Edit true 10003979 true Farkas E. true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 92247923 /api/authorship/92247923 2 0.16666667 false false false Author 10046470 /api/author/10046470 Biró Bernadett true 10046470 true Biró B. true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 92247924 /api/authorship/92247924 3 0.16666667 false false false Szabó K. true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 92247925 /api/authorship/92247925 4 0.16666667 false false false Author 10019799 /api/author/10019799 Veres Katalin true 10019799 true Veres K. true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 92247926 /api/authorship/92247926 5 0.16666667 false false false Author 10001543 /api/author/10001543 Csintalan Zsolt true 10001543 true Csintalan Zs. true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true PersonAuthorship 92247927 /api/authorship/92247927 6 0.16666667 false true false Author 10016378 /api/author/10016378 Engel Rita true 10016378 true Engel R. true false false AuthorshipType 1 /api/authorshiptype/1 0 true 0 true false true Institute 22369 /api/institute/22369 0 false false true Acta Botanica Hungarica szerkesztősége Editorial Office of the Acta Botanica Hungarica true true PublicationIdentifier 17093960 /api/publicationidentifier/17093960 PlainSource 6 /api/publicationsource/6 PublicationSourceType 10001 /api/publicationsourcetype/10001 true true true DOI DOI https://doi.org/@@@ true true 6 true GOLD true IDENTICAL 10.1556/034.62.2020.1-2.4 https://doi.org/10.1556/034.62.2020.1-2.4 false true PublicationIdentifier 21195775 /api/publicationidentifier/21195775 SwordSource 36 /api/publicationsource/36 PublicationSourceType 10007 /api/publicationsourcetype/10007 true true true REAL REAL http://real.mtak.hu/@@@ true true 36 true GREEN true 143229 http://real.mtak.hu/143229 true true PublicationIdentifier 17855420 /api/publicationidentifier/17855420 PlainSource 3 /api/publicationsource/3 PublicationSourceType 10003 /api/publicationsourcetype/10003 false true true Scopus Scopus http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-@@@ true true 3 true IDENTICAL 85090094164 http://www.scopus.com/record/display.url?origin=inward&eid=2-s2.0-85090094164 true true MtaRating 10485611 /api/mtarating/10485611 RatingType 10003 /api/ratingtype/10003 IV.
