Abstract

The leaves of three edible wild plants, Bunias erucago L. (Corn rocket), Lactuca perennis L. (Mountain lettuce) and Papaver rhoaes L. (Poppy) were analysed for their proximate composition, some nutraceutical components and total antioxidant capacity. The protein levels ranged from 2.7 to 4.1 g/100 g of the edible portion. The range of dietary fibre content was 3.8 to 6.4 g/100 g of the edible portion. The amount of ash, carbohydrate and lipid ranged from 1.7 to 1.9, 3.3 to 4.4 and 0.22to 0.45 g/100 g of the edible portion, respectively. Lipids consisted mainly of polyunsaturated fatty acids with the highest value for the Bunias erucago L. (71.8 % of total fatty acids) and Lactuca perennis L. (70.0 %). Potassium (374.0-521.0 mg/100 g) and calcium (204.8-331.8 mg/100 g) were the most representative macro-elements in the species studied. The values of vitamin E, b-carotene and total vitamin C are included in the range from 0.91 to 2.61 mg/100 g, from 1,957 to 2,631 mg/100 g and from 19.2 to 31.0 mg/100 g, respectively. Our results showed that the total antioxidant capacity performed by the Oxygen Radical Absorbance Capacity (ORAC) method, which ranges from 27.2 to 63.7 μmol TE/g, is highly justifiable by the high content of phenolic compounds (159-246 mg GAE/100 g)., Journal of Applied Botany and Food Quality, Vol 88 (2015), 115-119

Abstract

These days edible wild plants (EWPs) play a fundamental role in the Mediterranean diet, thanks to their content of mineral elements and bioactive compounds with proven benefits for human health. The present study aims to document ethnobotanical knowledge and uses of EWPs in Central Italy so that this knowledge will not be lost. During various nature fairs and exhibitions in Umbria three hundred subjects were interviewed face-to-face between March and May 2013-2015. The participants provided information on local plant names, where and when the plants were collected, part(s) used, categories used, folk medicinal uses, taste perception and other uses. The results were analyzed using two ethnobotanical indices: the Relative Frequency of Citation (RFC) and Relative Importance Index (RII). The 100 EWPs mentioned by the respondents belonged to 23 families, Asteraceae (33%), Brassicaceae (17%) and Lamiaceae (11%) being the most dominant. The part(s) used were leaves (49%), shoots (17%), flowers and inflorescences (10%). Fourteen food use categories were cited, of which boiled 31%, 28% raw, 12% in vegetable soups, 11% fried in fat, without or with beaten eggs. Twenty-seven plant species were also mentioned as having folk medicinal uses. [ABSTRACT FROM AUTHOR]
