This flowering behavior may be associated to the avoidance of competition by pollinators, as pointed out by Gentry (1974a, 1974b) in relation to bignon species that share pollinators. Despite these limitations, the present study gives valuable information on the potential use of I. horsfalliae flower extracts. Dr., Departamento de Botânica, IBB/UNESP, Caixa Postal 510, 18618-000 Botucatu-SP. In: BURLEY, J.; STYLES, B. T. For each Ipomoea, visitor relative abundance (RA) was calculated based on the total number of recorded visits. Rev. These two species were previously misidentified in Brazil as Ipomoea aristolochiaefolia and Ipomoea acuminata, respectively (Kissman & Groth, 1992; Lorenzi, 2000). New York: John Wiley & Sons, 1988. Caffeic acid protects the cells from the cytotoxic effect caused by UV-C; its photoprotective activity was evidenced in fibroblasts and epidermoid carcinoma cells. The visitors were collected and identified. Pollination mechanisms are greatly diverse in Angiosperms.Different pollination systems are found among weeds such as anemophily, entomophily, and autogamy. The mixture was filtered, and the residue was extracted twice more. https://doi.org/10.1080/14786419.2017.1335726, Radice M, Manfredini S, Ziosi P, Dissette V, Buso P, Fallacara A, Vertuani S (2016) Herbal extracts, lichens and biomolecules as natural photo-protection alternatives to synthetic UV filters. Anthesis started around 05:00h and lasted mostly until afternoon (Table 2), when the corollas wilted and fell off. Eur J Pahrmacol 555:218–25. 1). Jaboticabal climate is humid, subtropical with dry winter or Koeppen's Cwa (Aloisi & Demattê, 1974). See more ideas about flower seeds, seeds, flowers. Photochem Photobiol 86:1318–1326. This procedure was repeated three times, every 24 h. All mice were sacrificed by asphyxia in a CO2 chamber, 48 h after receiving their last radiation dose. Voucher specimen (COL 587134) was deposited at the Colombian National Herbarium, National University of Colombia. Sweetpotato (Ipomoea batatas) plays a critical role in food security and is the most important root crop worldwide following potatoes and cassava. The Scarlett O'Hara is a prolific climber spreading quickly. Ipomoea horsfalliae Hook., Convolvulaceae, flowers were collected from an experimental plot at CENIVAM (N 07° 08,422′ W 073° 06,960′) in March 2017. The non-specificity of these three weeds in relation to pollination is advantageous, considering that, at ruderal environments, pollinator availability is unpredictable (Baker, 1965; 1974); this adaptation is frequently associated to plants living in anthropic, disturbed environments (Valentine, 1978), such as the sites studied in this work. The production of interleukin (IL)-8 by stimulated THP-1 cells is used as a biomarker of sensitizing effect (Takahashi et al. 2003). [ Links ], BROWN, B. J.; MITCHELL, R. J.; GRAHAM, S. Competition for pollination between an invasive species (purple loosestrife) and a native congener. The sample units with the highest similarity were clustered (UPGMA), forming dendrograms in which the clusters were hierarchically arranged, with scales indicating similarity level. CC50 values were higher than 200 μg/ml for cells derived from hepatocellular carcinoma (HepG-2, 270 ± 80 μg/ml), monocytic leukemia (THP-1 > 500 μg/ml), normal kidney (HEK-293, 340 ± 110 μg/ml), and normal lung (MRC-5, 250 ± 50 μg/ml). Photoprotective Activity of Ipomoea horsfalliae Flower Extract. Ipomoea genus comprises ca. Darwiniana, v. 40, p. 25-32, 2002. 04:30h) to afternoon (approx. Some compounds isolated from plants are used as sunscreens because they are antioxidants and absorb UV radiation (Radice et al. The procedure was performed with 20 BALB/c mice, from 4 to 6 weeks of age, and a weight of 16 ± 2 g. The mice were depilated with Nair™ sensitive skin cream (Church and Dwight, Princeton, USA) 24 h before starting the experiments. LJS drafted the manuscript. Am. Am. 2011); their potential as primary sources of chemicals with protective effect against UV has not been studied yet. J. Dicaffeoylquinic acid, chlorogenic acid, … Levels of significance were calculated by one-way analysis of variance (ANOVA) followed by Tukey’s post-hoc and Student’s t tests. [ Links ], CARVALHO, W.
