    Serratula quinquefolia
    Opis:
    Genus Serratula is known for the presence of steroid compounds which belong to the group of ecdysones. Former phytochemical works from the late sixties and early seventies indicate, in some Serratula species, the occurrence of a phenolic glycoside-arbutin. This has been confirmed in the present work through finding an α,β-arbutin anomer in Serratula quinquefolia M.B. New botanical data concerning the classification of genus Serratula suggest that the species in question should be regarded as belonging to genus Klasea (currently a section of genus Serratula). There has been an attempt to find a key to the chemical division within the taxons.

    Opis:
    The occurrence of syringin in eight out of ten investigated plant species of the subtribe Centaureinae (Asteraceae) was reported. The compound was isolated from aerial parts of the plants by silica gel column chromatography of methanol extracts. Contents of syringin varied from 0.001 to 0.1% of the dried plant material. Centaurea bella Trautv. appeared to be the best source of this compound (0.1% dry wt.). Syringin has been reported for the first time from these plant species.

    Opis:
    Parmelia serrana A. Crespo, M.C. Molina & D. Hawksw. is reported here for the first time from Poland. The species has been recorded from more than 20 localities and exclusively on the bark of trees. Its general distribution, habitat requirements, morphology, secondary chemistry are provided and the differences between this species and similar taxa, especially P. saxatilis and P. ernstiae, are discussed.

    Opis:
    Nine known sesquiterpene lactones, including four lactucin-type guaianolides, four costuslactone-type guaianolides and one germacranolide, were isolated from roots of Lactuca sibirica (Asteraceae), six of which were glycoside derivatives. The chemosystematic significance of the compounds is discussed in the context of sesquiterpenoids present in roots of the closely related species Lactuca tatarica. A comparison of sesquiterpene lactone profiles indicate that the species can be differentiated on the basis of their germacranolide glycoside compositions.

    Opis:
    We analysed the essential oils of cultivated material of Thymus xtoletanus Ladero and its parents, Th. mastichina (L.) L. and Th. villosus subsp. lusitanicus (Boiss.) Coutinho, with seeds from the same locality in the centre of the Iberian Peninsula. The essential oil of Th. xtoletanus, which had not been analyzed previously, presented 1,8-cineole as the major component (25.5%), as was also the case for Th. mastichina (76.1%). Other components with a major presence in Th. xtoletanus and Th. villosus subsp. lusitanicus were [(Z)-β-ocimene (8.1%); camphor (4.5%); sabinene (3.2%); α-pinene (2.8%)], and [(Z)-β-ocimene (4.1%), camphor (9.8%), sabinene (2.8%), α-pinene (7.1%)], respectively. However, in the hybrid the components β-phelandrene (14.5%), limonene (6.9%), (E)-γ-bisabolene (3.5%), and viridiflorol (3.3%) stood out, inter alia, whereas their presence in the parents was limited. The study confirms the hybrid origin of Th. xtoletanus as intermediate between Th. mastichina and Th. villosus subsp. lusitanicus.

    Opis:
    From plantlets of Byblis liniflora Salisb. (Byblidaceae), propagated by in vitro culture, four phenylethanoid glycosides - acteoside, isoacteoside, desrhamnosylacteoside and desrhamnosylisoacteoside were isolated. The presence of acteoside substantially supports a placement of the family Byblidaceae in order Scrophulariales and subclass Asteridae. Moreover, the genera containing acteoside are listed; almost all of them appear to belong to the order Scrophulariales.

    Opis:
    In a study of the genus Cetrelia in Poland, four taxa have been identified, two of which, C. chicitae and C. monachorum, are reported for the first time from the country. All taxa differ in chemistry and subtle morphological characters. Cetrelia monachorum is the commonest member of the genus in Poland (237 records), whereas C. chicitae is known only from 6 records. All taxa are endangered, and three, C. cetrarioides, C. chicitae and C. olivetorum, appear to be critically so, thus deserving the category CR; although C. monachorum is the most frequent, it is not common and should be treated as endangered (EN). The distribution of all taxa, their habitat requirements, as well as morphology and secondary chemistry, are discussed.

    Opis:
    The paper presents the results of studies of Xanthoparmelia pulla group in Poland. The morphological and chemical analysis of herbarium materials confirmed the presence of four species of this group reported from Poland before. The study however, revealed considerable changes it the partiuclular species distribution. X. verruculifera, so far considered the most endangered species in the country, turned out to be the most frequent taxon. X. loxodes, regarded as common, has much less known localities than previously thought. This species was usually confused with X. verruculifera. Xanthoparmelia pulla is the rarest species and should be considered critically endangered in Poland. Most specimens of X. pulla collected in the country belong to X. delisei, which so far had only two historical records in Poland. All these taxa are characterized in terms of morphology, the content of secondary metabolites, ecology and distribution.
