“…Asparagus species are considered as plants with antioxidant and immunostimulant properties (Negi, Singh, Joshi, Rawat, & Bisht, ). Besides steroidal saponins, as the major bioactive compounds, A. acutifolius contains flavonoids such as kaempferol, quercetin, and rutin (Poljuha et al, ) that contribute to the aforementioned biological effects. Results from our previous work (Poljuha et al, ), presented in Table , showed three major phenolic components of A. acutifolius : quercetin‐3‐ O ‐rutinoside (247.90 µg/ml), isorhamnetin‐3‐ O ‐rutinoside (156.10 µg/ml), and kaempferol‐3‐ O ‐rutinoside (12.40 µg/ml).…”

“…According to the available data, A. acutifolius L. is very popular in other Mediterranean countries as well, like Italy (Salvatore et al, ), Spain (Garcia‐Herrera, Sanchez‐Mata, Camara, Tardio, & Olmedilla‐Alonso, ; Molina et al, ), France (Schulp, Thuiller, & Verburg, ), Cyprus (Della, Paraskeva‐Hadjichambi, & Hadjichambis, ), and Greece (Spanos, Raftoyannis, Panagiotis, & Xanthooulou, ). This species is a rich source of various phenolics such as quercetin and kaempferol, as well as ascorbic acid (Barros, Duenas, Ferreira, Carvalho, & Santos‐Buelga, ; Poljuha et al, ; Salvatore et al, ). It is a rich source of steroidal saponins as well, that have antifungal activity against the human pathogenic yeasts— Candida albicans , C. glabrata , C. tropicalis (Sautour et al, ).…”

The aim of this study was to determine the phenolic profile, antiproliferative, and pro‐apoptotic activities of Asparagus acutifolius, Tamus communis, and Ruscus aculeatus aqueous extracts against human bladder (T24) and lung cancer (A549) cell lines. Antiproliferative activity of the extracts at the concentration range from 0.5 to 4 mg/ml was measured by MTT test, after the incubation period of 4, 24, 48, or 72 hr. Pro‐apoptotic activity of selected plant extracts against T24 and A549 cells was analyzed by flow cytometry at the concentrations of 0.5, 1, and 2 mg/ml. The highest antiproliferative activity against both cancer cell lines was detected by T. communis aqueous extract. The highest pro‐apoptotic effect was achieved by A. acutifolius aqueous extract and its effect was similar against A549 and T24 cells. Practical applications Wild edible plants, such as wild asparagus, black bryony, and butcher’s broom represent important aspect of the Mediterranean diet. They are rich source of various natural bioactive compounds which express different biological activities (antioxidative, antiproliferative, antibacterial, anti‐inflammatory…). The current trend for natural and healthy diet, such as the Mediterranean diet, is in relation to the rapidly growing problem of chronic diseases in a modern society. Wild edible plants have a high direct‐use value using them in dishes containing mixed vegetables, in soup preparation, as natural additives in fermented natural products containing cheese or fish, in water infusions (natural drinks).

“…Sun et al (2007) found that the total phenol content of asparagus (A. officinalis) in acetone, methanol and aqueous extract, was 5.0±0.5, 4.9±0.7, and 4.9±0.9 [mg catehin equivalent/g dry weight], respectively. The investigation of Istrian wild asparagus showed that the results for the 40% EtOH and 96% EtOH extract of wild asparagus were 793±33 mg GAE/100g DW and 181±26 mg GAE/100 g DW, respectively (Poljuha et al, 2015).

Total Polyphenol Content and Antioxidant Activity of Wild and Cultivated Asparagus in Croatia

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 recent interest in wild edible plants is associated to their health benefits, which are mainly due to their richness in antioxidant compounds, particularly phenolics. Nevertheless, some of these compounds are metabolized after ingestion, being transformed into metabolites frequently with lower antioxidant activity. The aim of the present study was to evaluate the influence of the digestive process on the total phenolic contents and antioxidant activity of extracts from four wild edible plants used in the Mediterranean diet (Beta maritima L., Plantago major L., Oxalis pes-caprae L. and Scolymus hispanicus L.). HPLC-DAD analysis revealed that S. hispanicus is characterized by the presence of caffeoylquinic acids, dicaffeoylquinic acids and flavonol derivatives, P. major by high amounts of verbascoside, B. maritima possesses 2,4-dihydroxybenzoic acid, 5-O-caffeoylquinic acid, quercetin derivatives and kaempferol-3-O-rutinoside and O. pes-caprae extract contains hydroxycinnamic acids and flavone derivatives. Total phenolic contents were determined by Folin-Ciocalteu assay, and antioxidant activity by the ABTS, DPPH, ORAC and FRAP assays. Phenolic contents of P. major and S. hispanicus extracts were not affected by digestion, but they significantly decreased in B. maritima after both phases of digestion process and in O. pes-caprae after the gastric phase. The antioxidant activity results varied with the extract and the method used to evaluate the activity. Results showed that P. major extract has the highest total phenolic contents and antioxidant activity, with considerable values even after digestion, reinforcing the health benefits of this species.
