“…The results of our analysis are not in accordance with the Ferrara et al (2011), the study which found that the phenolic content of A. acutifolius (41.97±1.95 mg/100 g) was higher compared to A. officinalis (27.62±1.11 mg/100 g). From the foregoing, it can be concluded that the phenolic profile of populations from different geographical areas varies considerably (Poljuha et al, 2015).…”

SUMMARYAsparagus is an interesting vegetable as a part of a healthy diet and has been widely studied due to the high nutritional value and potential positive effects on human health. Wild asparagus (Asparagus acutifolius L.) grows along the Adriatic coast and islands, while the cultivated asparagus (A. officinalis L.) is mostly grown in the eastern region of Croatia. The aim of this study was to determine total polyphenol content (measured spectrophotometrically) and antioxidant activity (DPPH) in wild and cultivated asparagus. No significant differences in total polyphenol content were found between wild and cultivated asparagus. The highest content of polyphenols in wild asparagus was 6. [mg GAE/g fresh weight] and 49.60 [mg GAE/g dry weight], and in cultivated asparagus it was 4.52 [mg GAE/g fresh weight] and 50.93 [mg GAE/g dry weight]. Antioxidant activity measured using DPPH (2,2-diphenyl-1-picrylhydrazyl) method showed statistically significant difference. Higher antioxidant activity was measured in cultivated than in wild asparagus. The results also indicate that increased polyphenol content leads to higher antioxidant activity, but more so in the cultivated asparagus. Based on the results, the cultivated asparagus is an excellent alternative to wild asparagus that should be protected from over-harvesting, thus preventing devastation of plant diversity of islands and coast.

“…The supernatants were lyophilized, treated with 3% sulfosalicylic acid (500 µL) to precipitate any protein fraction still present, and centrifuged again (Iriti et al, 2009). For the analysis of total (free and protein) amino acids, ~10 mg of seeds flour were hydrolysed with 0.5 mL of 6 N HCl containing 0.05% thioglycolic acid and nor-Leu as an internal standard at 110°C for 20 h and treated as previously reported (Ferrara et al, 2011). Aliquots of hydrolysed and nonhydrolysed samples were directly analysed by using a Biochrom30 amino acid analyser (Biochrom, Cambridge, U.K.).…”

Background. 'Gallo Matese' beans are known as a typical legume of Southern Italy and continue to be consumed as a traditional food preserving the diversity of this region. Nonetheless, no information about the nutritional values of this legume is available. The objective of the present investigation was to determine the nutritional value and metabolic profile of 'Gallo Matese' beans. Results. 'Gallo Matese' beans contain high levels of proteins (22.64 g/100 g) and essential amino acids (8.3 g/100 g). Furthermore, different unsaturated fatty acids contribute to the total amount of lipids (0.97 g/100 g); among them, the essential PUFA α-linolenic (0.48 g/100 g) and linoleic (0.39 g/100 g) acids are the most abundant. The total phenol content was revealed and ABTS and ORAC-fluorescein methods were applied to determine the radical scavenging capabilities of the extract with and without boiled treatment. Finally, a decrease in trypsin and chymotrypsin inhibitory activities was estimated before and after the boiling procedure. Conclusion. The data obtained show that 'Gallo Matese' beans are a functional food with healthy qualities. Overall, these results are useful to promote their cultivation and consumption, thus preserving Italian beans biodiversity due to consumer interest in choosing a healthy diet, such as the Mediterranean diet.

“…Harvesting impacts could also vary depending on harvesting practices. The spears of A. acutifolius are traditionally cut above ground level, when they are tall and lignified at the base (Ferrara et al, 2011). In this way, plants continue growing through the lateral buds which remain in the lower part of the stem.…”

“…According to nutritional studies, the spears of A. acutifolius are rich in flavonoids and vitamin C, showing a high antioxidant activity even when examined after boiling (FuentesAlventosa et al, 2007;Martins et al, 2010;Morales et al, 2011). Specifically, their content of ascorbic acid is more than fivefold higher than that from the cultivated asparagus, A. officinalis L. (Ferrara et al, 2011).…”

In the Mediterranean region, some wild edible species such as Asparagus acutifolius L. are still harvested and even marketed. Considering the great interest of this species, including its recreational, commercial and agronomic uses, we aimed to study its natural supply and its current scale of harvesting. Nearly 50 plants were monitored in two sites of Central Spain. An experimental harvest of 100% of spears was conducted during spring 2008-2009 to estimate spear production per plant and per hectare. Plants were also monitored but not harvested in 2010-2011 at Site 1 to document real gathering practices and its influence on yield. Spear production ranged from 5.0 to 12.8 g per plant and from 4.0 to 8.9 kg ha -1 , reaching the top-ranked values in May (30-60% of total yield). Between-site variations on yield were mainly related to spear number rather than to spear weight, whereas weather conditions influenced annual yields. The percentage of plants harvested by local foragers varied from 26 to 47%. A slight but not significant trend for collecting the largest spears was recorded. According to spear number in harvested (1.8-2.5 spears) and non-harvested plants (1.3-1.5 spears), gathering seemed to promote the growth of new spears, although further research is needed to assess its influence in the long term. Results suggest that foraging is a time-consuming practice, thus social and cultural factors may explain its high appreciation in present times.Additional key words: applied ethnobotany; gathering; non timber forest products; spear yield; wild edible plants. ResumenPotencial de las plantas silvestres comestibles en la región mediterránea: producción y presión recolectora del espárrago triguero (Asparagus acutifolius L.)En la región mediterránea, especies como el espárrago triguero (Asparagus acutifolius L.) siguen siendo recolectadas y a veces incluso vendidas en mercados locales. Dado el interés de esta especie, tanto recreativo como agronómi-co o comercial, en este trabajo se estima su producción natural y su presión recolectora en la actualidad. Para ello se realizó el seguimiento de casi 50 esparragueras silvestres en dos localidades del centro de España. En la primavera de 2008 y 2009 se recolectaron el 100% de los espárragos para estimar el número y peso de espárragos por planta y por hectárea. La presión recolectora se ha estudiado durante los años 2010-2011 en las mismas plantas de una de las dos poblaciones. La producción estimada fue de 5,0-12,8 g por planta y 4,0-8,9 kg ha -1 , alcanzando los valores más altos en mayo (30-60% del rendimiento total). Entre localidades aparecieron mayores diferencias en el número de espárra-gos que en el peso de los mismos. Las condiciones meteorológicas influyeron en los rendimientos anuales. Se observó que el 26-47% de las esparragueras fueron cosechadas por recolectores locales. Se detectó una ligera pero no significativa tendencia a recolectar los espárragos de mayor tamaño. Basándonos en el número de espárragos de las plantas recolectadas (1,8-2,5 espárrag...
