“…It is a species closely related to leek ( Allium porrum L.) and is customarily supposed as its wild progenitor [ 1 ]. A. ampeloprasum contains a broad series of compounds, among which polyphenols, with antioxidant properties [ 2 , 3 ] and recently an extract obtained from the leaves was used to synthetize silver nanoparticles used in catalytic reduction of 4-nitrophenol with antioxidant activity [ 4 ]. Allium ampeloprasum var.…”

The present study was carried out to determine some biochemical characteristics, in particular the total polyphenol content and the free radical scavenging activity, of the extracts recovered from bulbs and aerial parts (these last often considered as by-products) of two landraces of A. ampeloprasum var. holmense cultivated in Southern Italy. For the first time, the capacity of the extracts of these landraces to inhibit the formation of biofilm of different Gram-negative and Gram-positive bacteria and to affect the metabolism of the cells present within the bacterial biofilm was evaluated. All extracts exhibited an amount of total polyphenols not lower than 2.86 mg/g of dried product and revealed a noteworthy antioxidant activity, with EC50 values not exceeding 4.95 mg. In both cases, the aerial parts extracts were more effective than the bulb extracts, which also showed a minor amount of total polyphenols. The extracts inhibited mainly the adhesive capability of Pseudomonas aeruginosa and Staphylococcus aureus, by 95.78% and 85.01%, respectively. The extracts demonstrated to inhibit also the metabolism of the bacterial cells reaching levels up to 90%. Finally, as assessed by the assays performed on the 24-h preformed biofilms, all the extracts were also capable to cause a reduction in bacterial biomass and to affect their metabolism.

Stomach ache is one of the most chronic and debilitating abdominal pains. Medicinal plants are one of the most accessible sources for treating diseases like gastrointestinal disorders. In this review, we investigate and report the most important medicinal plants recommended by Persian medicine for treating stomach aches and comparing them with their proven effects in modern medicine. Gastric pain was probed in Persian medicine reliable textbooks such as Cannon of Medicine (Ibn Sina), Tibbe-Akbari (Muhammad Akbar Arzaani), The Complete Art of Medicine (Kitab Kamil as-Sinaa at-tibbiyya) (Haly Abbas), Explanation of insults and signs (Kermani) Tohfeh Al-Mo'menin (Seyed Mohammad Momen Tonekaboni), and some notes were taken. The results showed that Panicum miliaceum, Punica granatum, Solanum nigrum, Calicotome spinosa, Tamarindus indica, Cuminum cyminum, Prunus domestica, Matricaria recutita, Viola odorata, Plantago psyllium, Berberis vulgaris, Pyrus communis, Linum usitatissimum, Vitis vinifera were the most important plant sources used in treating the stomach ache according to Persian medicine. The findings of this study showed that the useful effects of many recommended plants in Persian medicine are confirmed by recent scientific researches and are reliable.

“…The IC 50 value is the concentration that caused half maximal inhibition of the radical. Researchers have proposed that extracts with IC 50 less than 50 µg/ml are regarded as very strong antioxidants, 50-100 µg/ml; strong antioxidants, 101-150 µg/ml; moderate antioxidants, and those above 150 µg/ml weak antioxidants [39,40]. The IC 50 of the extract was found to be 40.91 ± 0.19 µg/ml indicating that the extract is a very strong antioxidant.…”

Plant extracts that have antioxidant activities show promising effect in the management of many diseases initiated by oxidative stress. The present study evaluates the phytochemical composition and in vitro antioxidant potentials of methanol extract of Duranta erecta leaves. The extract was subjected to phytochemical screening, DPPH inhibition, ferric reducing antioxidant power (FRAP), nitric oxide determination, antioxidant vitamins and minerals composition analysis. All analyses were carried out using standard biochemical methods. The phytochemical evaluation of the plant extract showed the presence of flavonoids (24.20 ± 0.14 mg QE/g), Alkaloids (15.87 ± 1.71 mg/g), total phenol (12.73 ± 0.61 mg GAE/g), tannins (9.24 ± 0.03 mg TAE/g), terpenoids (8.90 ± 0.96 mg/g), steroids (2.65 ± 0.55 mg/g) and saponins (5.55 ± 0.76 mg/g). The in vitro antioxidant determination showed that the extract had antioxidant properties in a concentration dependent manner. The antioxidant property of the sample was compared to that of ascorbic acid (for DPPH and nitric oxide determination) and gallic acid (for FRAP) as standards. The antioxidant mineral composition of the extract revealed the presence of zinc (1.82 ± 0.03 mg/100g) and selenium (0.59 ± 0.04 mg/100g). The antioxidant vitamins composition of the extract showed moderate concentrations of vitamin C (0.35 ± 0.01 mg/100 g) and vitamin E (0.68 ± 0.07 mg/100g). The result of this study revealed that methanol extract of Duranta erecta leaves could be a good source of antioxidants.
