This research has been conducted to evaluate the effect of extraction methods on the main group of compounds, cytotoxicity, anti acetylcholinesterase (AChE) and antioxidant activity of Trachyspermum ammi fruits. Methods: To compare the quality of extracts earned from maceration and reflux techniques, the amounts of total phenolics, flavonoids and antioxidant property of T. ammi’s fruits extracts were determined; moreover, the cytotoxic activity against Human acute lymphoblastic leukemia (ALL) cell lines (NALM-6) was conducted using MTT assay. Anti-acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) activity of both extracts were also examined by Ellman’s method. Results: The extraction yield of the plant was significantly higher for maceration compared to reflux extraction. Also, both antioxidant activity and total flavonoid contents (IC50=132.95 µg/mL and 140.15 mg catechin/g dry extract, respectively) showed higher amounts considerably in the maceration extraction. In reverse, the content of phenolic compounds (147.28 mg gallic acid/g dry extract and 16.6 mg thymol/g dry extract) was elevated in the refluxed extract. The result exerted moderate inhibition on butyrylcholinesterase activity (IC50= 394.161 µg/mL) and cytotoxicity (IC50 =166.92±1.76 μg/mL for NALM-6 cell line) of the extract using maceration. Conclusion: The maceration method could provide additional amounts of major constituents and greater biological properties compared to the reflux technique.}, keywords = {Biological effect,Extraction,maceration,reflux,Trachyspermum ammi}, url = {https://www.rjpharmacognosy.ir/article_54433.html}, eprint = {https://www.rjpharmacognosy.ir/article_54433_52c314c41b3d77fecfcf79cfae36ae97.pdf} }
