This study was focused on investigation of phenolic compounds, total phenolic contents and antioxidant activities of some
wild onions (Crocus chrysanthus (SDA1), Hyacinthella campanıslata (SDA2), Muscari armaniacum (SDA3), Ornithogalum
armeniacum (SDA4), Gagea granatelli (SDA5), Hyacinthella heldreichii (SDA6), Muscari neglectum (SDA7), Ornithogalum
lanceolatum (SDA-8). SDA-3 had the maximum total phenolic content, with the range of 88.19 mg/100 g, followed by SDA-1
(82.50 mg/100 g). SDA-1 (29.32%) exhibited the best antioxidant activity, followed by SDA-3 (27.92%). The major phenolic
compound of SDA-3, SDA-4, SDA-5, SDA-6 and SDA-8 was (+)-catechin, with the ranges of 35.23, 30.76, 33.72, 44.42
and 50.85 mg/100 g, respectively. The dominant phenolic acid of SDA-1 (86.15 mg/100 g) and SDA-7 (22.07 mg/100 g)
was determined as gallic acid. Additionally, SDA-2 contained the highest content of isorhamnetin (53.87 mg/100 g). Results
indicate that the bulbs of studied plants are potential sources of phenolic compounds and their methanolic extracts have
antioxidant activity.
