For each visitor, abundance was registered considering the number of recorded visits. The promiscuous and opportunistic features of the flowers were shown, with such type of adaptation to pollination being advantageous to weeds since pollinator availability is unpredictable at ruderal environments. Plant in moist, humus rich, well drained soil and keep a regular watering schedule throughout the year.

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.

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.

Dicaffeoylquinic acid, chlorogenic acid, scopoletin, glycosylated cyanidin, pelargonidin, and kaempferol were identified as major components of I. horsfalliae flower extract. IHFE seems not to have the potential to kill the cancerous cells tested in this study since it showed CC50 values > 250 μg/ml.

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. In Table 1, the experimental exact masses of M+ and [M + H]+ identified in IHFE are shown together with the criteria used for compound identification, and with the main ion-fragments obtained at the HCD under different collisional energies.

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.
