Human beings have used wild edible plants (WEPs) for food since ancient times. The poor and underprivileged people of the district of Malakand, Pakistan, also depend on wild edible plants (WEPs) to fulfill their food and nutrition needs. Wild edible plants (WEPs) are a potential solution for overcoming food shortages for families living in rural areas. The current study evaluated the ethnobotanical, nutritional, and elemental potential of some wild edible plants (WEPs) commonly used by local people in the district of Malakand, Pakistan. Ethnobotanical information was collected from local people through a semi-structured questionnaire. The ethnobotanical information collected about wild edible plants revealed that two wild edible species belong to the family Fabaceae, two plant species belong to the family Polygonaceae, and one plant species belongs to each family Amaranthaceae, Brassicaceae, Chenopodiaceae, Malvaceae, Oxalidaceae, and Portulaceae. The plants collected were all herbs, and the parts used as edible parts were mostly leaves and young shoots. All the collected plants were predominantly used as vegetables by local people. The proximate nutritional analysis was carried out according to the official methods of AOAC (from 2016). The proximate nutritional analysis revealed that the selected WEPs are a good source of important nutrients like carbohydrates, proteins, fibers, fats, and caloric energy. The proximate nutritional analysis of selected WEPs revealed that the highest (%) moisture content was calculated in Nasturtium officinale W.T. Aiton (90.45 ± 0.3); the highest dry matter (%) was present in Oxalis corniculata L. (21.60 ± 0.2); the highest ash (%) in Chenopodium album L. (17.80 ± 0.3); the highest crude fibers (%) in Meliolotus indicus (L.) All (16.45 ± 0.5); the highest crude protein (%) in Meliolotus indicus (L.) All (14.40 ± 0.1%); the highest crude fats (%) in Rumex hastatus Don. (3.80 ± 0.04); the highest percentage of carbohydrates in Portulaca oleracea L. (65.38 ± 0.6); and the maximum energy value was calculated for Portulaca oleracea L. (321.38 ± 0.4 Kcal/100 g). The elemental analysis of wild edible plants (WEPs) was carried out through energy-dispersive X-ray analysis (EDX). The EDX analysis showed that these WEPs consist of crucial and imperative elements such as C, O, N, P, Mg, K, S, Ca, Al, Si, Cl, Fe, Cu, Na, and Zn, which are integral parts of the human diet. Following the results of the EDX elemental analysis, Portulaca oleracea accounted for the highest concentration (%) of carbon, Oxalis corniculata accounted for the highest concentration (%) of oxygen, and Nasturtium officinale accounted for the maximum concentration of nitrogen (9.70%). The current study revealed that the research area is rich in diversity of wild edible plants (WEPs), a cheap and economical food source for locals. The study also showed that these wild edible plants (WEPs) possess all the crucial nutrients and elements imperative for human food and health. These wild edible plants (WEPs) will play a key role in a sustainable food system in the future.

Alternanthera philoxeroides and Hypophthalmichthys molitrix offer significant nutritional benefits. This study evaluates the proximate composition, amino acid profile, GC-MS analysis, FT-IR spectroscopy, SEM and EDX, and color values of edible paper sheets (EPSs) derived from Alternanthera philoxeroides incorporating different levels of Hypophthalmichthys molitrix flesh. The protein content in the EPSs varied based on fish flesh incorporation, peaking at 52.66% in Ap100/Hm300 (Non-boil). Protein and carbohydrate contents showed an inverse correlation across EPSs, with the highest carbohydrate content of 60.89% in sample Ap400/Hm0 (Boil). Lipid content was also found to correlate with H. molitrix flesh content in EPSs, ranging from 1.59% to 18.41%. Amino acid analysis identified 11 types, with methionine as the most prevalent, followed by leucine, phenylalanine, and lysine. GC-MS analysis revealed 51 bioactive compounds, including carbonic acid, hentriacontane, and various fatty acids. FT-IR analysis showed characteristic bonds, while color analysis displayed L* values ranging from 24.37 to 30.97. SEM analyses depicted the microstructure, surface view, and elemental composition of the EPSs, and EDX showed an abundance of Ca, N, K, O, C, Mg, Na, P, Cl, Mn, and Fe. Therefore, EPSs prepared from A. philoxeroides and H. molitrix could offer a promising approach for effectively utilizing aquatic biomass and providing both plant and animal nutrients to consumers.
