Ipomoea cairica is a perennial herb with vegetative and sexual reproduction whose pollination biology was studied at Jaboticabal, São Paulo, in southeastern Brazil (21º15'22" S, 48º18'58" W, 575 m altitude) by Maimoni-Rodella et al. Jena: Fischer, 1954. In Botucatu, poor occurrence of pollinators may be due to the fact that the study sites were located near natural forests, which may retain the flower visitors more hardly. Biol., v. 47, p. 425-436, 1987. Consequently, IHFE might be a good candidate for research on natural products for human health. Samples were placed on cassettes for histology and suspended in a p-formaldehyde solution (500 ml, 2% w/v in phosphate buffer, 0.1 M, pH 7.2) for 24 h. They were washed with water (3 h), dehydrated in ethanol solutions (500 ml, 70, 80, 96, or 100% v/v) for 2 h, and included in paraffin. It has been proposed that extracts with CC50 > 90 μg/ml could be classified as non-cytotoxic, while extracts with CC50 < 90 μg/ml as moderately or highly cytotoxic according to the WHO (2019). The study sites are shown in Table 1. J.

Their phenolic compounds can scavenge reactive oxygen species, reduce skin alterations caused by UV exposure, and prevent aging (Estrella-Parra et al. Photochem Photobiol 86:1318–1326. New York: Harper & Row, 1974. Keywords: Ipomoea cairica (L.) Sweet leaves; natural deep eutectic solvents; static headspace gas chromatography … I. horsfalliae ethanolic extracts were analyzed by ultra-high efficiency liquid chromatography–high-resolution mass spectrometry. For I. cairica, the "cornucopia" pattern seems to be associated with the "steady state" pattern, following Gentry (1974a), since there was a constant production of few flowers all round the year, and one period of several weeks when the flower production was more intense. A.; REYNOLDS, J. F. Statistical ecology. Measurements of floral parts were based on ten flowers from five individuals. All species are pantropical climbers that occur spontaneously on cultivated land, roadsides and other areas often disturbed by human activity. 2011); in the present study, the protocol described by Parise et al. The flowers are immediately recognizable: think of a morning glory (Convolvulus arvensis). [ Links ], STUCKY, J. M.; BECKMANN, R. L.

IHFE toxicity and skin sensitization potentials need to be investigated using accurate and relevant tests, and the mechanistic explanation of the photoprotective effect should be provided.

Finally, the opportunistic pollination feature of the three Ipomoea studied was emphasized since the highest similarities were observed among different species occurring in the same site. 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. A. ; ESPÍNDOLA, C.
