“…In fact, references to this plant from Spanish and Northwest African researchers are scarce (Bremner et al, 2009;Pardo-de-Santayana et al, 2007). Even so, only in the last decade the chemical characterization and evaluation of its therapeutic efficacy have been described (Bremner et al, 2009;Grosso et al, 2007;Luı´s, Domingues, Gil, & Duarte, 2009;Paulo et al, 2008;Vitor et al, 2004).…”

Pterospartum tridentatum Willk. (prickled broom) is an autochthonous plant, common in Portuguese territory. The yellow flowers are used in traditional medicine, as a potential cure for all body illnesses, mainly to treat throat irritations or for diabetes, hypertension and hypercholesterolemia therapy. Despite its traditional use, no toxicological assessment has been performed to our knowledge. A high antioxidant activity of P. tridentatum flower water extract was found, in good agreement with its electrospray ionisation-mass spectroscopy (ESI-MS) spectrum which revealed the presence of several flavonoids, such as luteolin-O-(O-acetyl)-glucuronide, luteolin-Oglucuronide or isorhamnetin-O-hexoside. Mitocondrial respiratory rates (state 4, state 3 and FCCP-stimulated respiration) and respiratory indexes (respiratory control and P/O ratios) showed no consistent decrease of respiratory and phosphorylative efficiencies for the concentrations tested (up to 500 mg.mL 71 ). Cytotoxicity evaluation, using MTT assay, was in agreement with the previous results. In conclusion, for the concentration range commonly used, P. tridentatum flower usage can be regarded as harmless and credible.Keywords: antioxidant capacity; cytotoxicity; oxidative phosphorylation; phytotherapy; Pterospartum tridentatum (L.); Willk.; toxicologic evaluation Pterospartum tridentatum Willk. es una planta auto´ctona comu´n en el territorio portugue´s.

“…Wild fruits and vegetables have been reported to be rich in micronutrients such as vitamin A and iron (Acipa et al., 2013; Oryema, 2014). Nevertheless, it is important to appreciate that information available on the utilization of wild fruits and vegetables for household nutrition among rural communities is largely qualitative (Bharucha & Pretty, 2010; Loki & Ndyomugyenyi, 2016a,b; Pardo‐de‐santayana et al., 2007). However, the actual contribution of those wild food resources in terms of the Recommended Dietary Allowance (RDA) for critical nutrients such as vitamin A and iron has largely remained unknown.…”

Nutritional knowledge and attitude of a population greatly affect intake of essential micronutrients. Much of the understanding on the impact of nutritional knowledge and attitude on nutrient intake has been derived from studies conducted among affluent societies using commercial food products. However, information on the link between status of nutritional knowledge and attitude on intake of essential nutrients from wild fruits and vegetables among rural communities is largely lacking. This study examined the status of nutritional knowledge and attitude associated with intake of vitamin A and iron from wild fruits and vegetables among rural households in Acholi subregion of northern Uganda. A cross‐sectional study design making use of individual household questionnaire and proximate dietary recall of a calendar year consumption period involving 248 randomly selected rural households was applied. Results showed that households had good nutritional attitude but poor nutritional knowledge. Status of knowledge was dependent on nutrition training (p = 0.028; coefficient, β = 0.710) and age of the respondent (p = 0.044; β = −0.023), whereas status of attitude was predicted by age of the respondent (p = 0.014; β = 0.048). Consumption of wild fruits and vegetables contributed adequately to the dietary vitamin A and iron requirements of the households. The results have demonstrated that intake of vitamin A and iron from wild fruits and vegetables among rural households is associated with good nutritional attitude but poor nutritional knowledge. A concerted effort is necessary to improve household nutritional knowledge for better utilization of wild fruits and vegetables.

“…Asian gastronomy also uses a strong aromatic component; herbs, leaves, and seeds of wild species are key ingredients used to make vegetal oils or flavor food (Bortolotto et al 2015;Ju et al 2013;Li et al 2015;Rajasab & Isaq 2004). All over the world, leaves, flowers, and fruits of wild native plants have been used for flavor (steeping in water) and to prepare beverages (fermenting and distilling) that were used in rituals or events with cultural and religious significance (Bortolloto et al 2015;Estrada-Castillón et al 2014;Hong et al 2015;Pardo de Santayana et al 2007;Sõukand et al 2013).…”

“…Furthermore, in the Mediterranean region seasoning is a very important practice, primarily for the taste and aroma it imparts to food but also for the nutritional value of the main species consumed (Barros et al 2011b;Pardo de Santayana et al 2007), as well as for its role in preservating sauces, sausages, meat, and fish (Póvoa et al 2006).
