Abstract
Abstract
The study investigated total phenolic-flavonoid content, antioxidant activity, and phytochemical compounds across various parts (bulb, stem, leaf, and flower) of the endemic Bellevalia sasonii, commonly known as hyacinth, belonging to the Asparagaceae family. Phenolic content was highest in bulb extracts (117.28 μg GAE) and lowest in stems (45.11 μg GAE). Conversely, leaf extracts exhibited the highest flavonoid content (79.44 μg QEs), while stems showed the lowest (22.77 μg QEs). When the antioxidant activities were compared, by DPPH method leaf = flower > bulb > stem; in ABTS and CUPRAC methods bulb > flower > leaf > stem, respectively. Considering the results in general, it was revealed that bulbs and flowers displayed higher activity, while stem exhibited lower activity compared to other parts. The phytochemical analysis identified 53 active substances, with 27 absent in any extract and 15 detected across all extracts. The distribution of phytochemicals varied among parts, with bulbs, stems, flowers, and leaves also different numbers. The LC-MS/MS analysis revealed prominent metabolites including fumaric acid in leaves, caffeic acid in bulbs, and cosmosiin and quinic acid in flowers. This study provides foundational insights into B. sasonii, an important endemic plant in Türkiye, laying the groundwork for future research on its medicinal and ecological roles.
