Opis:
Seasonal studies on size-fractionated phytoplankton productivity (biomass and primary production), marker pigments, and species composition and abundance were carried out in the Cochin estuary (CE), located on the southwest coast of India, to identify the critical environmental factors that control the consistent preponderance of diatoms. The overall results of the study showed a significant contribution of small-sized phytoplankton, specifically nanophytoplankton (2—20 μm), to the total chlorophyll a and primary production in the estuary, regardless of seasons. Diatoms constituted the major phytoplankton taxa, showed an exceptional seasonal scale increase in numerical abundance during the post-southwest monsoon. The relative increase in fucoxanthin (biomarker of diatoms) over other marker pigments substantiated the numerical dominance of diatoms throughout the sampling periods. This is the first study in the CE in which phytoplankton marker pigments have been detected and elucidated the seasonality of functional groups based on HPLC/chemotaxonomy analytical approaches. The prevalence of high DiatDP and diatom chlorophyll a equivalent (estimated by CHEMTAX), further confirmed the preponderance of diatoms in the CE, despite the intermittent dominance of cyanophytes and cryptophytes (monsoon period). The consistent increase in SPM levels (> 25 mg L—1), established at all sampling stations, indicated that the water column turbidity might be one of the significant environmental factors hindering the growth of large-sized phytoplankton (ca. >20 μm) in the CE even if the system invariably holds high inorganic nutrients, irrespective of seasons

Opis:
Hydro-ethanolic extracts of flowers from four Verbascum species were evaluated for the phenolic content, composition, and antioxidant activity using Folin-Ciocalteu assay, HPLC-DAD analysis, and DPPH assay, respectively. The highest flavonoid content was detected in V. sinuatum extract from Khoramabad (19.91 mg RE/g DW). The extract of V. pseudo-digitalis from Maymand yielded the highest amount of total phenols, together with the highest apigenin and luteolin levels (55.62 mg GAE/g DW, 12.18 and 88.13 μg/mg DW, respectively), while that of V. songaricum from Ardekan showed the highest naringin content (12.44 μg/mg DW). The extract of V. songaricum from Shirmard exhibited the highest quercetin and rutin levels (1.0 and 24.24 μg/mg DW, respectively), whereas that of V. sinuatum from Ardekan had the highest caffeic acid content (7.78 μg/mg DW). The antioxidant activity of Verbascum samples showed IC50 values from 45.12 to 226.62 μg/mL

Opis:
The medicinal and culinary properties of Angelica archangelica L. have been known and valued since the Middle Ages. Ingredients of essential oil and coumarins found in this plant are to a large degree responsible for its pharmacological activity. This study is a review of the literature of the most important biologically active compounds present in herbal raw materials: root (rhizome with roots) and angelica fruits. Research shows that the content of individual compounds of the essential oil and coumarin fraction is variable, which may point to a large intraspecific variation. Therefore, these compounds may be good markers for identifying taxa or chemotypes in chemotaxonomic research valuable for the herbal medicine and pharmaceutical industry.

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.

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.

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.

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:
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.
Jak dotąd, rozpoznano w Polsce 40 gatunków z rodzaju Pertusaria DC. (por. Hanko 1983; Fałtynowicz 2003; Kossowska 2008). Na podstawie budowy morfologicznej i składu wtórnych metabolitów porostowych analizie poddano dwa gatunki z tego rodzaju, P. multipuncta (Turner) Nyl. i P. ophthalmiza (Nyl.) Nyl., które charakteryzują się podobną morfologią plech, ale różnią się chemizmem. P. multipuncta, podobnie jak P. ophthalmiza, cechuje się najczęściej cienką, gładką, niekiedy spękaną, biało-szarą plechą. Owocniki, zwykle pojedyncze, są zagłębione w brodawkach plechy przypominających soralia, a tarczki są płaskie lub lekko wypukłe i przyprószone ziarenkowatymi sorediami. Worki są jednozarodnikowe. Gatunki te różnią się chemicznie. P. multipuncta reaguje na czerwono z PD i zawiera kwas fysodalowy (często także protocetrariowy), natomiast P. ophthalmiza nie reaguje z PD i zawiera kwasy tłuszczowe (Hanko 1983; Chambers et al. 2009). Dotychczas z terenu Polski częściej notowana była P. multipuncta (Fałtynowicz 2003), P. ophthalmiza zaś była podana tylko raz przez Hanko (1983). Gatunek ten jednak nie został ujęty na liście porostów Polski, a pierwsze dane o jego występowaniu na terenie kraju w polskiej literaturze lichenologicznej pojawiły się w pracy Kukwy et al. (2008). Przeprowadzone badania wykazały, że większość notowań P. multipuncta z Polski należy do P. ophthalmiza lub do innych gatunków porostów. P. multipuncta została potwierdzona na terenie naszego kraju tylko z jednego stanowiska w Gorcach. Rozmieszczenie obu gatunków w Polsce przedstawia rycina 1.

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.

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:
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-cis polyprenols were accompanied by α-trans counterparts. This report describes several new plant species that may serve as natural sources of long chain polyprenols.

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.
