Composition of Anthocyanins, Specific Sugars, and Organic Acids in Wild Edible Aromatic and Medicinal Vegetables

Abstract

This study investigates the bioactive compound profiles of 12 wild edible plant species from the Amaranthaceae, Apiaceae, Asteraceae, Brassicaceae, Caryophyllaceae, Lamiaceae, Malvaceae, Polygonaceae, and Urticaceae families, consumed as aromatic and medicinal vegetables by local communities and forming part of the natural vegetation of Mount Ergan. The plants were collected and analyzed for their anthocyanin, organic acid, and sugar contents, using advanced liquid chromatography techniques. Statistically significant differences were observed between species for each compound analyzed, highlighting their diverse phytochemical profiles. Malva neglecta, Brassica nigra, and Taraxacum phaleratum exhibited the highest anthocyanin contents, suggesting their strong potential as natural antioxidant sources. Organic acid levels were notably elevated in Polygonum cognatum, T. phaleratum, Urtica dioica, and M. neglecta, which positions these species as promising candidates for use as natural acid regulators in food and pharmaceutical formulations. In terms of sugar content, Chenopodium album, Mentha longifolia, and T. phaleratum had the lowest levels, while M. neglecta, Cirsium arvense, P. cognatum, and Tragopogon buphthalmoides showed significantly higher concentrations, indicating potential applications in the development of natural sweeteners. This study's findings provide valuable insights into the phytochemical diversity of these wild plant species, emphasizing their potential utility in health nutrition, pharmaceuticals, and cosmetics. This study emphasizes the significance of investigating underexploited plant species for their bioactive chemicals and illustrates their potential contribution to the development of sustainable, natural product-based solutions for diverse industrial uses.
