view. Thus, the influence of the cultivation conditions of two undervalued food plants inherent to the spring- summer period in Mediterranean conditions was studied: purslane ( Portulaca oleracea L.) and quirquiña ( Porophyllum ruderale (Jacq.) Cass). According to the previous ethnobotanical review, these two species have been rooted in the traditional gastronomy of the Valencian coast (Spain).As objectives of this research, it was established to compare in organic farming conditions and in wild conditions:1) the nutritional characteristics of two species; 2) the bioactive components present. Since wild species are well adapted to local environmental conditions, they can ensure constant production under adverse environmental conditions and could be considered as vegetables for the local productive structure, as well as a beneficial source for health. II. M aterials/ M éthods a) Plant material and sample preparation The harvest was carried out in the spring- summer season of 2020 under two growing conditions: 1) organic farming conditions; 2) wild conditions in the same area of the Valencian coast within latitudes N 39º45'13'' and longitudes W 0º12'21''.The wild plants were collected in the areas close to the cultivation area and their brief description is summarized in Table 1. Table 1: Description of studied plants P. oleracea is a widespread edible and medicinal plant with expanding interest as some previous research indicates that its shoots are a rich source of bioprotective nutrients (Spina et al ., 2008; Yang et al ., 2009; Franco et al ., 2011; Iranshahy et al ., 2017; Li et al ., 2019). P. ruderale has also been used in traditional medicine (Conde-Hernández y Guerrero-Beltrán, 2014),although the review work by Marques et al. (2020) highlights the lack of scientific work on this plant, except for some research on the chemical characterization of its essential oil (Fonsceca et al ., 2006; Santos et al ., 2016). The phytochemical constituents of the studied plants have some bioactive properties that are summarized in Figure 1. © 2022 Global Journals 1 Year 2022 34 Global Journal of Science Frontier Research Volume XXII Issue ersion I VI ( D ) Influence of Cultivation Conditions on the Nutritional Composition and Bioactive Components of Two Undervalued Edible Plants ( Porophyllum Ruderale and Portulaca Oleracea )
