Does above sea level elevation affect phytochemical profile of wild garlic?

Allium ursinum L., otherwise known as wild garlic, is a wild relative of onion and garlic along with many other species of the numerous Allium genus. Wild garlic is a wild edible plant which usually grows in forests, preferably in shade and sometimes in vicinity of water streams. It is prevalent throughout Europe and western Asia, from lowlands to highlands. Being described as a wild plant, the plant itself has adapted to various environmental conditions. In the past, wild garlic was used as a remedy which refers to wild garlic having compounds that promote good health. Those properties are mostly attributed to the organosulfur compounds and antioxidants produced in plants as a secondary metabolites. Allium species are characterized by an abundance of organosulfur compounds which are directly responsible for the distinct flavor and pungent odor, while polyphenols represent a group of numerous compounds that possess antioxidant properties. The aim of this study was to investigate the differences in phytochemical profiles between bulbs and leaves of wild garlic originating from 8 different locations, namely differences in antioxidant capacities, total polyphenol contents, volatile profiles, and amino acid. Moreover, effect of above sea elevation on antioxidant capacities, total polyphenol contents, volatile profiles, and amino acid levels in bulbs and leaves of wild garlic was investigated as well. Antioxidant capacities and total polyphenol contents were determined by spectrometric methods (DPPH, FRAP, ORAC, TPC) while volatile profile and amino acid levels were determined using GC-MS and HPLC, respectively. In total, 23 volatile compounds were determined in leaf samples, while in bulb samples 28 volatile compounds were determined. Also, 12 amino acids were quantified in leaf samples, while in bulb samples 14 amino acids were quantified. Furthermore, statistical analysis (factorial ANOVA) showed how the quantity of investigated compounds is not only dependent on the plant’s organ, but on above sea level elevation as well. Therefore, significant interaction between plant organ and elevation was established in 56.5% of determined compounds. In leaves of wild garlic, the effect of elevation was not significant in most of the investigated compounds, while in bulb samples that grew on lower elevation, higher antioxidant capacity and amino acid content was observed. Meanwhile, bulbs from higher elevation exhibited higher level of volatile compounds compared to bulbs from lower elevation.
