Background
Oxalis pes-caprae L. is a plant considered within the group of so-called Wild Edible Plants (WEPs). The particularity of these plants is that they grow only with the natural resources at their disposal. Unfortunately, these types of plants are undervalued, being regularly uprooted from the fields. (2)
Conclusions
Therefore, this research provides new information that reaffirms the capacity of Oxalis pes-caprae L. (WEP) to be a plant with great future progression due to its nutritional quality since it could be used in the food, nutritional, or pharmaceutical fields. Further research must be conducted to assay the biomass production and the costs of recommending farmers not to destroy this plant in their fields.
Methods
Therefore, this study aimed to valorize the Oxalis pes-caprae plant, analyzing the proximate composition (sugars, organic acids, minerals, amino acids profile, fatty acids content, and volatile profile) of the plant shoots (flower, leaves, and stem) to demonstrate the full potential of this WEP. (3)
Results
The results showed that Oxalis pes-caprae can be considered a natural source of minerals; furthermore, 19 essential and non-essential amino acids were found. Regarding the fatty acid profile, flowers are an important source of linoleic acid, and leaves present a high amount of α-linolenic acid. (4) Conclusions: Therefore, this research provides new information that reaffirms the capacity of Oxalis pes-caprae L. (WEP) to be a plant with great future progression due to its nutritional quality since it could be used in the food, nutritional, or pharmaceutical fields. Further research must be conducted to assay the biomass production and the costs of recommending farmers not to destroy this plant in their fields.
