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.

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.

The presence of poly-ci's-prenols of chain length 20-60 isoprene units or longer in leaves of plants belonging to Combretaceae family was shown to be a common feature in this group of plants. The polyprenols of this type were found in half of the 20 species studied. In most cases the polyprenols occurred in the form of fatty acid esters. Only in one species — Combretum molle, the polyprenols were found in the form of free alcohols. The amount of long-chain polyprenols varied with the plant species; the richest source was C. molle (about 4% of dry mass of leaves). Polyprenol groups characteristic of other systematic families of plants were not found in the Combretaceae studied

The occurrence of long-chain polyprenols in leaves of plants of Lauraceae, Tiliaceae and Magnoliaceae families was studied. Separation of groups of polyprenols differing in the size of molecules was performed by thin-layer chromatography. In all studied species long-chain polyprenols were detected. The total polyprenol content in leaves reached values as high as 3% of their dry weight. In the studied species belonging to Lauraceae family a fraction of polyprenols composed of 10-14 isoprene units was present. In species of Tiliaceae and Magnoliaceae polyprenols composed of 9-12 and 10-12 isoprene units were present, respectively. Differences in polyprenol profile characteristic for each family studied were observed. These results were confirmed by HPLC. The structure of these polyprenols was examined by NMR spectrometry and in representative species studied polyprenols exibited the typical poly-cis structure. The effect of insolation on the rate of accumulation of polyprenols was documented.

The paper presents results of study on two morphologically very similar lichens in Poland, P. multipuncta (Turner) Nyl. and P. ophthalmiza (Nyl.) Nyl. (Pertusariales, Ascomycota). Previously, specimens were determined using only thallus characters and spot test reaction, with no data on lichen substances. This led to several misidentifications. After the revision of all available material of P. multipuncta from Poland it appeared to be reported correctly only from one locality in Gorce Mts. Most of other specimens belong to P. ophthalmiza, which has not been recorded in Polish lichenological literature until 2008.

The occurrence of polyprenols in leaves of over 340 species of dendroflora in natural habitats in the regions of Hanoi and Hue in Vietnam was studied. Plant material was collected in the late autumn (October/November) during the end of a vegetation season. Leaves of about 200 plant species did not contain detectable amounts of polyprenols in contrast to few systematic families, e.g. Moraceae,Euphorbiaceae, where polyprenols were highly abundant and their pattern could be used as a chemotaxonomic criterion. Most often dominating polyprenols were prenol-11 and prenol-12. In several angiosperm species prenol-13 and detectable amounts of prenol-14 were also found. The incidence of prenol-13 and -14 was not restricted to a specific taxonomic group since species exhibiting domination of such longer chain polyprenols belonged to various systematic families. In some plants (e.g. Ceiba pentandra) α-cispolyprenols were accompanied by α-transcounterparts. This report describes several new plant species that may serve as natural sources of long chain polyprenols

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.

The plant family Pinaceae is known to produce a set of unusual fatty acids in the seed oils. In Turkey it has been less studied in respect to the fatty acid and tocochromanol (tocopherols and tocotrienols) composition of the seed oils, particularly in terms of chemotaxonomy. This study examined the fatty acid, tocopherol, tocotrienol and plastochromanol-8 content of Pinus L. taxa naturally growing in Turkey (Pinus nigra subsp. pallasiana, P. nigra subsp. pallasiana var. pyramidata, P. halepensis, P. sylvestris, P. pinea, P. brutia, P. radiata, P. pinaster). The fatty acids (oleic, linoleic, α-linolenic, ∆5-taxoleic, pinolenic and coniferonic acid) and tocochromanols are valuable components of Pinus seed oils, in the family Pinaceae. Unsaturated fatty acid comprises ~90% of the seed oil. While γ-tocopherol was found to be the largest component of all Pinus seed oil, β-tocotrienol was not found at all. Total tocopherols in the studied taxa was much higher than total tocotrienols. The distribution of fatty acid and tocochromanol patterns in the genus Pinus is discussed, and in particular the presence of ∆5-UPIFA acids such as taxoleic and pinolenic acids, as well as common and distinguishing features that may contribute to knowledge about the taxonomy and phylogeny of pines.

From the aerial parts of Zoegea leptaurea subsp. mesopotamica (Czerep.) Rech. (syn Zoegea mesopotamica Czerep.), 9α-hydroxyparthenolide was isolated. This compound was identified by spectral methods (1H NMR and 13C NMR). This research confirmed earlier indications about the presence of 4,5-epoxygermacranolides in the Zoegea L. genus. Thus, distinctive chemistry feature of plants in this taxon has chemotaxonomic implications.

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.

Var i ous spe cies and cultivars of Ericaceae fam ily were checked for the pres ence of long-chain polyprenols in their leaves. In the ge nus Rhododendron no polyprenols were found in the ever-green spe cies, while they were pres ent in the de cid u ous type. The polyprenols were of chain-length of 14-20 isoprene res i dues and they oc curred in the form of acetic acid esters. The polyprenol accu mu la tion is dis cussed with respect to se nes cence of leaves.

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.

Lipopolysaccharides of seven Bradyrhizobium strains and three whole-cell fatty acid preparations from bacteria isolated from nodules of Sarothamnus scoparius (Common Broom) were studied for the presence of very long chain (ω-1)-hydroxy fatty acids. Several such fatty acids were identified. Among them, straight-chain as well as mono- and dimethyl branched acids with chains in the range from 26 to 34 carbon atoms were found. Pyrrolidides and 4,4-dimethyloxazoline derivatives were used to determine the branching position. Carbons at the (ω-10) and/or (ω-11) positions in alkyl chains were points of attachment of methyl groups. These data complete the structure of bradyrhizobial lipid A with important details. The obtained results can be applied in the chemotaxonomy of Bradyrhizobium.
