“…HE extracts of P. lusitanica fruits harvested in the three different locations (PL1, PL2, and PL3) were used. Cells were incubated, for 24 h or 48 h, with different concentrations of extracts (25,50,100,200, 500, and 750 µg/mL) as depicted in Figure 1, and the results were compared with the respective positive control cells (nonexposed cells). As observed, 24 h exposure of Caco-2 cells with P. lusitanica fruit HE extracts did not produce a cytotoxic effect as cell viability was close to 100% of the control, at all tested concentrations (Figure 1A-C: gray bars), with no statistical difference (p > 0.05).…”

“…Among the unexplored plants, Prunus lusitanica L., belonging to the Prunus L. genus of the Rosaceae family (Prunaceae or Amygdaloideae subfamily), is an example. This plant, considered a relict tree from the Tertiary, is distributed mainly in the Iberian Peninsula, Northern Morocco, and Macaronesia [25]; it is also known as laurel cherry, cherry bay, or Portuguese laurel [26]. P. lusitanica is an evergreen shrub with alternate and oval leaves, resembling those of bay laurel, whose small flowers (10-15 mm diameter) are produced on erect or spreading racemes in late spring, and whose fruits, consisting of small cherry-like drupes (8-13 mm in diameter), ripen in late summer or early autumn and are of dark purple or black color [27].…”

Prunus lusitanica L. is a shrub belonging to the genus Prunus L. (Rosaceae family) that produces small fruits with none known application. Thus, the aim of this study was to determine the phenolic profile and some health-promoting activities of hydroethanolic (HE) extracts obtained from P. lusitanica fruits, harvested from three different locations. Qualitative and quantitative analysis of extracts was performed using HPLC/DAD-ESI-MS and antioxidant activity was assessed by in vitro methods. Antiproliferative/cytotoxic activity was determined on Caco-2, HepG2, and RAW 264.7 cells, anti-inflammatory activity was assessed using lipopolysaccharide (LPS)-stimulated RAW 264.7 cells, and the antidiabetic, antiaging, and neurobiological action of extracts was determined in vitro by assessing their inhibitory effect against the activity of α-amylase, α-glucosidase, elastase, tyrosinase, and acetylcholinesterase (AChE). Results showed that P. lusitanica fruit HE extracts from the three different locations showed identical phytochemical profile and bioactivities, although small differences were observed regarding the quantities of some compounds. Extracts of P. lusitanica fruits contain high levels in total phenolic compounds, namely, hydroxycinnamic acids, as well as flavan-3-ols and anthocyanins, primarily cyanidin-3-(6-trans-p-coumaroyl)glucoside. P. lusitanica fruit extracts have a low cytotoxic/antiproliferative effect, with the lowest IC50 value obtained in HepG2 cells (352.6 ± 10.0 μg/mL, at 48 h exposure), but high anti-inflammatory activity (50–60% NO release inhibition, at 100 μg/mL extract) and neuroprotective potential (35–39% AChE inhibition, at 1 mg/mL), and moderate antiaging (9–15% tyrosinase inhibition, at 1 mg/mL) and antidiabetic (9–15% α-glucosidase inhibition, at 1 mg/mL) effects. The bioactive molecules present in the fruits of P. lusitanica deserve to be further explored for the development of new drugs of interest to the pharmaceutical and cosmetic industry.

Background. The study of the geographical distribution of species is very useful for understanding the patterns and processes that explain biodiversity and are raw materials for conservation planning based on the generation of maps identifying areas with a high probability of occurrence. Objective. To determine the potential distribution (PD) of C. dodecandra and land use variations in the Yucatan Peninsula (YP). Methodology. A Species Distribution Model (MDE) was used to find areas with suitable environmental conditions for wild populations of Cordia dodecandra, fifteen environmental variables were used to model the optimal conditions for the species and to create the model for PD using the MaxEnt 3.3.3k program, the georeferenced presence records available from herbaria and the data collected in the field were used to map the Known Distribution (DC) of C. dodecandra. The corrected PD (DPC) was calculated by incorporating the land use data obtained from INEGI into the model. Results. The PD of C. dodecandra in the YP was 2,501,938 hectares. The main environmental variables that affect the PD of the species were the type of climate, the precipitation of the wettest month, the precipitation of the wettest quarter and the annual precipitation. CPD decreased by 2 per cent (265,439 hectares) compared to PD. Implications. The analysis identifies areas with a high probability of finding the species, which would help to initiate projects for the development of this species aimed at its conservation. Conclusion. The areas of potential distribution with the greatest probability of presence of Siricote in the Yucatan Peninsula are: the Calakmul Biosphere Reserve, the southern and central part of the state of Yucatan and the central area of the municipality of Felipe Carrillo Puerto (Quintana Roo).

“…Relict and rare tree species represent evolutionary heritage for plant conservation (Pardo et al, 2018; Tang et al, 2017). Often taxonomically isolated, they provide a unique opportunity to understand both past and recent biogeographical and evolutionary process (Kozlowski et al, 2012), as for millions of years these plants have been able to cope under changing environments on earth (Garfì et al, 2011; Tang et al, 2011).…”

Background and Research aims The extinction of relict and rare tree species is accelerated by habitat loss and climate change. Pleodendron costaricense is a critically endangered tree, with only four mature individuals known in Southern Pacific Costa Rica. With the discovery of three additional trees, we set out to learn more about P. costaricense’s natural history and attempt the first successful germination. Methods We collected fruits from two trees and carried out preliminary germination trials in a nursery at the study site. We also used camera traps in one of the fruiting mother-trees to understand natural dispersal mechanisms of the species. Results Although plagued by excessive levels of invertebrate predation, we were able to germinate and produce 59 saplings ready for restoration planting. Five mammal species were detected on the camera traps feeding on the fruits, along with one primate potentially using the fruits as a topical medicine. Conclusion P. costaricense can be propagated ex-situ, potentially with greater success using stimulating hormones. To improve production rates, future efforts should focus on the protection of germinating seeds and saplings from seed predators. We also identified numerous potential natural mammalian seed dispersers, mostly in the family Procyonidae. Implications for Conservation Given the propagation knowledge we have developed, the active restoration efforts of the saplings by Osa Conservation to help increase population numbers, and the strict protection of the two fruiting mother trees, there is now the possibility to attain a positive conservation outcome for this critically endangered species.
