Worldwide, there is a growing interest in the consumption of wild edible plants that possess high nutritional value and health-promoting bioactive compounds. Asparagus stands out among these plants due to its cultivated varieties as well as its wild forms. In Türkiye, asparagus consumption has increased more than tenfold over the past 5 years, and it is estimated that nearly half of the consumed asparagus comes from wild species obtained from local markets. Wild asparagus from the Iğdır Plain is in high demand locally and exported to nearby regions. This study was conducted to determine the biochemical composition and evaluate the antioxidant capacities of wild edible asparagus naturally distributed in the Iğdır Plain. A total of 35 wild asparagus spear samples were collected from different regions and analyzed for specific phenolic acids, flavonols, free amino acids, ascorbic acid, total saponin content, and antioxidant activities using DPPH and ABTS methods. According to the results, the wild asparagus samples collected from the Iğdır Plain exhibited higher levels of total phenolic acids, flavonols, amino acids, ascorbic acid, and saponins compared to the commercial cultivated variety. However, when evaluated in terms of antioxidant capacity, the wild samples showed lower activity than the commercial variety in both DPPH and ABTS assays. Statistical analyses revealed a significant level of variation among the wild asparagus genotypes in the region. Notably, samples collected from Iğdır city center, as well as regions A1, A15, A22, A24, and A27, were found to be particularly rich in nutritional and health-related compounds. This study presents the first scientific data on the biochemical composition and antioxidant capacity of wild edible asparagus naturally growing in the Iğdır region. Furthermore, it is suggested that collecting seeds from promising regions and cultivating these genotypes could help prevent the extinction of these valuable wild species due to overharvesting.
在全球范围内，人们对食用具有高营养价值和促进健康生物活性化合物的野生可食用植物的兴趣日益浓厚。芦笋因其栽培品种和野生形态在这些植物中脱颖而出。在土耳其，过去5年里芦笋的消费量增长了十多倍，据估计，消费的芦笋近一半来自从当地市场获取的野生品种。来自伊兹密尔平原的野生芦笋在当地需求量很大，并出口到附近地区。本研究旨在确定自然分布于伊兹密尔平原的野生可食用芦笋的生化成分，并评估其抗氧化能力。从不同地区共采集了35个野生芦笋嫩茎样本，采用DPPH和ABTS法分析其特定酚酸、黄酮醇、游离氨基酸、抗坏血酸、总皂苷含量及抗氧化活性。结果表明，与商业栽培品种相比，从伊兹密尔平原采集的野生芦笋样本中总酚酸、黄酮醇、氨基酸、抗坏血酸和皂苷的含量更高。然而，在抗氧化能力方面进行评估时，野生样本在DPPH和ABTS试验中的活性均低于商业品种。统计分析显示该地区野生芦笋基因型之间存在显著差异。值得注意的是，从伊兹密尔市中心以及A1、A15、A22、A24和A27地区采集的样本被发现富含营养和与健康相关的化合物。本研究提供了关于自然生长在伊兹密尔地区的野生可食用芦笋生化成分和抗氧化能力的首批科学数据。此外，建议从有前景的地区收集种子并培育这些基因型，这有助于防止这些珍贵的野生物种因过度采摘而灭绝。
