摘要

阿尔茨海默病是痴呆症的主要原因，痴呆症会随着年龄的增长而增加。评估了通塞利（土耳其东部）特有种通塞利A.tuncelianum（Kollmann）Özhatay等人球茎提取物和精油的胆碱酯酶抑制作用和抗氧化潜力。乙酸乙酯提取的部分具有最高的酚类水平、1,1-二苯基-2-苦基肼和硫代巴比妥酸抗氧化能力。乙酸乙酯组分的乙酰胆碱酯酶抑制率最高（15.98±2.76%），丁酰胆碱酯酶抑制率为47.33±3.27%。二烯丙基二硫化物（49.8%）、二烯丙基三硫化物（27.9%）和烯丙基甲基三硫化物（6.9%）是精油的主要成分。本文表明，通氏A.tuncelianum的乙酸乙酯部分可能是抗氧化剂和抗胆碱酯酶成分的有效来源。

Chemical and morphological characterization of Allium tuncelianum (Amaryllidaceae) and its antioxidant and anticholinesterase potentials

Alzheimer’s disease is the main reason for dementia, which increases with age. Cholinesterase inhibition and antioxidant potentials of extracts and essential oils from bulbs of A. tuncelianum (Kollmann) Özhatay & al., an endemic species to Tunceli (easthern Turkey), were evaluated. The fraction extracted of ethyl acetate had the highest phenolics level, 1,1-diphenyl-2-picrylhydrazyl, and thiobarbituric acid antioxidant capacity. Also, the ethyl acetate fraction presented the highest acetylcholinesterase (15.98 ± 2.76%), and butyrylcholinesterase inhibition (47.33 ± 3.27%). Diallyl disulfide (49.8%), diallyl trisulfide (27.9%) and allyl methyl trisulfide (6.9%) were found to be the major components of essential oil. This paper shows that the ethyl acetate fraction of A. tuncelianum could be a potent source of antioxidant and anticholinesterase components.
