Corn tassel (CT) is a waste part of the corn plant. It is a good co-product and rich in terms of bioactive compounds and phytochemicals. This research tried to show the phenolic profile, antioxidants, anticholinergic activities, and antibacterial properties of CT ethanol extract. The phenolic content analysis of the CT was determined quantitatively by LC-MS/MS, and the antioxidant capacity was measured using ABTS, DPPH, Cu-Cu, and Fe-Fe reducing methods. The anticholinergic measurements of CT were detected by inhibition of acetylcholinesterase (AChE). The antibacterial activity was determined by MIC and disc diffusion methods. Many phenolic compounds such as vanillic acid, caffeic acid, fumaric acid, acetohydroxamic acid, butein, myricetin, resveratrol, catechin hydrate, and 4-hydroxybenzoic acid were detected in ethanol extract of CT. The obtained plant ethanol extract had a 7.04% DPPH value, while it showed ABTS activity at 9.45%. Moreover, it had a 0.10 mg/mL inhibition effect on the AChE in terms of IC values. The ethanol extract of the CT had an antibacterial property on the investigated bacteria at different ratios. In conclusion, this research aims to consider CT as a source of phenolic compounds and to reveal its bioactive properties and its effects on the treatment of some diseases.
玉米须（CT）是玉米植株的废弃部分。它是一种优质的副产品，富含生物活性化合物和植物化学物质。本研究试图展示玉米须乙醇提取物的酚类成分、抗氧化剂、抗胆碱活性和抗菌特性。通过液相色谱 - 串联质谱法（LC-MS/MS）对玉米须的酚类含量进行定量分析，并使用ABTS、DPPH、Cu-Cu和Fe-Fe还原法测量抗氧化能力。通过抑制乙酰胆碱酯酶（AChE）来检测玉米须的抗胆碱活性。通过最小抑菌浓度（MIC）和纸片扩散法测定抗菌活性。在玉米须乙醇提取物中检测到许多酚类化合物，如香草酸、咖啡酸、富马酸、乙酰氧肟酸、紫铆因、杨梅素、白藜芦醇、儿茶素水合物和4-羟基苯甲酸。所获得的植物乙醇提取物的DPPH值为7.04%，而其ABTS活性为9.45%。此外，就IC值而言，它对AChE具有0.10 mg/mL的抑制作用。玉米须乙醇提取物对所研究的细菌具有不同程度的抗菌特性。总之，本研究旨在将玉米须视为酚类化合物的来源，并揭示其生物活性特性及其对某些疾病治疗的作用。
