Plantas medicinais do SUS: espécies comuns da região de Bauru-SP

This work deals with present and discuss mainly the chemical composition and pharmacological activities of each species of the National List of Medicinal plants of interest to SUS (RENISUS) contained in scientific articles that are found in the Bauru-SP region. Such information compiled in this study may help in the advancement of scientific research, promoting the speed in bibliographic queries these species. In the present work was carried out consultation papers and described in the form of literature review, published information of the species listed in Renisus specific to the Bauru-SP region are: Aloe spp* (A. vera or A. barbadensis), Schinus terebinthifolius = mastic Schinus, trimera Baccharis, Mikania spp* (M. glomerata and M. laevigata), Vernonia condensata, Tabebuia avellanedeae, Chenopodium ambrosioides, Momordica charantia, Phyllanthus spp* (P. amarus, P. niruri, P. tenellus and P. urinaria), Stryphnodendron adstringens = Stryphnodendron barbatimam, pulegium Mentha, Mentha spp* (M. crispa, M. piperita or M. villosa), Plectranthus barbatus = Coleus barbatus, Persea spp* (gratissima or P. americana P.), Bauhinia spp* (B. affinis, B. forficata or B. variegata), Copaifera spp*, Morus sp*, Eugenia uniflora or brasiliana Myrtus*, Psidium guajava, Syzygium spp* (S. jambolanum or S. cumini), Passiflora spp* (P. alata, P. edulis or P. incarnata), Punica granatum and Casearia sylvestris. Studies have shown that the use of plants as alternatives treatment and sustainable use of Brazilian biodiversity has a breakthrough in research regarding the chemical composition of each species of RENISUS relationship. Many phytochemical studies are reported compiled with possible pharmacological indications of each species. Thus enabling the use and production of herbal medicines in SUS

Controle de qualidade e obtenção de extratos de espécies vegetais do cerrado brasileiro com potencial etnofarmacológico

ANVISA (National Health Surveillance Agency) has published in recent years, laws that regulate the stages of the control of plants derivatives, including tests of macro and microscopic botanical identification, phytochemical determination, tests of authenticity and purity, microbiological testing, among other parameters. All the analytical procedures of plant drugs control required by law must be based on the Brazilian Pharmacopoeia, other Pharmacopoeias recognized by ANVISA or quality control guides of plant species published by the World Health Organization (WHO). This study aimed to evaluate some pharmacognostic, phytochemical screening and microbiological control of plant species of the Brazilian cerrado, which have indicated ethnopharmacological: Byrsonima intermedia (Bi), Bauhinia holophylla (Bh) and Myrcia bella (Mb). In addition, certain parameters were determined for obtaining extracts from plants sprayed and dried. These data are important to obtain new scientific information from Brazilian plants with therapeutic potential.

Eine tragfähige Datenbrücke – Phänologische Beobachtungen im Amtsblatt des Kantons Schaffhausen 1876–1950

The international standardisation of national meteorological networks in the late nineteenth century excluded biotic and abiotic observations from the objects to be henceforth published in the yearbooks. Skilled amateurs being in charge of three meteorological stations in Canton Schaffhausen (Switzerland) and their successors managed to continuously publish phenological observations gathered in the station environment alongside with meteorological data in the official gazette of this Canton from 1876 to 1950, i.e. up to the onset of phenological network observations in Switzerland. At least ten observations are available for 51 plant and animal phenological phases. Long series were assembled (N → = 30) for 14 plant phenological observations, among them for the first flowering of snowdrop (Galanthus nivalis), of hazel (Corylus avellana), of horse chestnut (Aesculus hippocastanum), of winter rye (Secale cereale) and of grape vine (Vitis vinifera) as well as the beginning of hay, winter rye and grape harvesting. Only the bare data were published without any metadata. The quality of 10 long series (N →=60) was checked by investigating the biographical and biological background of key observers and submitting their evidence to graphical (meteorological plausibility check of outliers) and statistical verification. The long term observers, mostly schoolteachers and high school professors, had a good knowledge of botany and the quality of their observations – disregarding obvious printing errors – is surprisingly good. A number of long series (seven) was completed with applicable data from the Swiss Phenological Network up to 2011. Besides anthropogenic shifts (beginning of hay and grape harvest) there is a contrast between a global warming-related earlier flowering of snowdrop and hazel and a later occurrence of grape vine flowering.

Palynological record and radiocarbon dates for sediment core T89-16, Congo River mouth

We present a high-resolution reconstruction of tropical palaeoenvironmental changes for the last deglacial transition (18 to 9 cal. kyr BP) based on integrated oceanic and terrestrial proxies from a Congo fan core. Pollen, grass cuticle, Pediastrum and dinoflagellate cyst fluxes, sedimentation rates and planktonic foraminiferal d18O ratios, uK37 sea-surface temperature and alkane/alkenone ratio data highlight a series of abrupt changes in Congo River palaeodischarge. A major discharge pulse is registered at around 13.0 cal. kyr BP which we attribute to latitudinal migration of the Intertropical Convergence Zone (ITCZ) during deglaciation. The data indicate abrupt and short-lived changes in the equatorial precipitation regime within a system of monsoonal dynamics forced by precessional cycles. The phases of enhanced Congo discharge stimulated river-induced upwelling and enhanced productivity in the adjacent ocean.

AMS radiocarbon dates and pollen analysis of ODP Hole 175-1078C

ODP Site 1078 situated under the coast of Angola provides the first record of the vegetation history for Angola. The upper 11 m of the core covers the past 30 thousand years, which has been analysed palynologically in decadal to centennial resolution. Alkenone sea surface temperature estimates were analysed in centennial resolution. We studied sea surface temperatures and vegetation development during full glacial, deglacial, and interglacial conditions. During the glacial the vegetation in Angola was very open consisting of grass and heath lands, deserts and semi-deserts, which suggests a cool and dry climate. A change to warmer and more humid conditions is indicated by forest expansion starting in step with the earliest temperature rise in Antarctica, 22 thousand years ago. We infer that around the period of Heinrich Event 1, a northward excursion of the Angola Benguela Front and the Congo Air Boundary resulted in cool sea surface temperatures but rain forest remained present in the northern lowlands of Angola. Rain forest and dry forest area increase 15 thousand years ago. During the Holocene, dry forests and Miombo woodlands expanded. Also in Angola globally recognised climate changes at 8 thousand and 4 thousand years ago had an impact on the vegetation. During the past 2 thousand years, savannah vegetation became dominant.
