Salvia glutinosa L. na terenie Poznania

75%
The paper describes a new locality of the mountain apophyte Salvia glutinosa recorded in Poznan. Three patches of this species were found by the roadside near an alder forest, close to the Lake Rusałka. This is the first record of this species in the Wielkopolska region.
Szałwia hiszpańska (Salvia hispanico) nazywana chią, to gatunek rośliny należącej do rodziny jasnotowanych (Lamiaceae). W przemyśle spożywczym coraz częściej wykorzystuje się nasiona szałwii hiszpańskiej do produkcji żywności. Są one dodawane m.in. do pieczywa, batonów, musli, a nawet masła. Surowiec ten jest popularny ze względu na wysoką zawartość błonnika pokarmowego oraz kwasów tłuszczowych omega-3. Badania naukowe wskazują na wysoki potencjał prozdrowotny nasion chia. Wymienia się tu przede wszystkim działanie hipoglikemiczne i hipolipemiczne. Nasiona chia charakteryzują się również wysoką aktywnością przeciwutleniającą.
The moldavian dragonhead (Dracocephalum moldavica L., Lamiaceae) is an annual plant native in Central Asia and naturalized in Eastern and Central Europe where it is used in folk medicine as antiseptic and stimulating remedy. We carried out qualitative and quantitative phytochemical investigations on moldavian dragonhead herb and on its extracts (tincture and infusion). Plant samples were gathered in different stages of the ontogenesis from cultures in Hungary and Romania (Transylvania). In herb gathered during the reproductive stage of the ontogenesis we measured 0.83% (v/m) of essential oil, in which we identified by GC analysis five main components: geranyl acetate: 33.1%; geranial: 28.2%; neral: 19.8 %; geraniol: 8.2% and neryl acetate: 2.4%. In the essential oil distilled from tincture the geranyl acetate (58.2%) was the main component while in the volatile oil distilled from infusion, the major compound was geraniol (60.1%). A methanolic extract of the herb was investigated by HPLC. Following on-line analysis of spectra, five components were classified as flavonoids; rosmarinic acid was identified by addition of authentic standard. The amount of two phenol carboxylic acids (caffeic and rosmarinic acid) was measured by TLC-densitometry. High values of phenolic compounds were measured in samples gathered during the vegetative stage of the ontogenesis, such as: rosmarinic acid: 2.84 g%; caffeic acid: 50.3 mg%; total flavonoids: 0,58 g%; tannins: 12.9 g%.
Scutelaria altissima L. is a very rare alien anthrophytic species in Poland. It is found in the western laceland forest where it goes through its full life cycle, including developing fruits and seeds. Every year, it extends its territory due to favorable natural conditions. For the first time, the species has been included in the geographic-historical group of holoagriophytes.
There are some taxonomic uncertainties within the Turkish members of Satureja. It is extremely difficult to distinguish some Satureja species because of their great morphological similarity. Satureja species are used as herbal teas and spices, and for this reason they are important commercial and medicinal plants. In this study, the leaf anatomy and hair features of species were examined by LM and SEM. The investigated species can be divided into two main groups, as bifacial and equifacial leaves according to mesophyll structure. They can be secondarily divided into two types based on the midrib region in cross section, as projecting or nonprojecting. Thirdly, two main vascular bundle types can be identified in transverse section according to the presence or absence of sclerenchyma. All species have glandular, peltate and capitate, and nonglandular hairs and diacytic stomata, but the covering hairs differ between species. The leaves of fifteen Satureja L. species were studied in order to assess anatomical variations that may serve as distinguishing characters, and to evaluate their significance for the taxonomy of the genus.
New or rare synanthropic plants in Poland. 2. Agastache urticifolia (Lamiaceae). Fragmenta Floristica et Geobotanica Polonica 10: 57–65. Kraków. PL ISSN 1640 629X. ABSTRACT: The authors report a spontaneous occurrence of Agastache urticifolia (Benth.) Kuntze, which is a new genus and species of Polish flora. Several dozen of its specimens were discovered on an inactive sediment tank at the Cracow Soda Factory in Kraków Jugowice in July of 2002. Most likely, the plant was brought here with the soil used for recultivation of the sediment tanks. The paper contains a detailed description of the species, its general distribution, and the characteristic properties of the A. urticifolia habitat in Kraków. The authors could not establish the exact way in which this plant has come to Poland.
