    Prevention and treatment of noncommunicable diseases such as neurodegenerative diseases, diabetes, and hyperpigmentationusing medicinal plants has attracted increasing attention during the past few decades. In this study, Colutea cilicicaBoiss. & Balansa extracts (ethyl acetate, methanol, and water) were evaluated against key enzymes involved in neurodegenerativediseases, diabetes, and hyperpigmentation. The antioxidant (free radical scavenging, reducing power, ?-carotene/linoleic acid, and phosphomolybdenum) and metal chelation properties were also investigated. The methanol extracts of C.cilicica vigorously inhibited the activities of acetylcholinesterase and butyrylcholinesterase (1.33 and 0.68 mg galantamineequivalents (GALAE)/g extract, respectively). It was observed that C. cilicica extracts possessed a higher inhibitory potentialfor ?-glucosidase (2.71–1.23 mmol acarbose equivalents (ACAE)/g extract) than that for ?-amylase (0.57–0.12 mmol ACAE/gextract). The water extract of C. cilicica showed potent radical scavenging capacity against DPPH (2, 2-diphenyl-1-picrylhydrazyl)and ABTS (2,2’-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (42.46 and 57.70 mg trolox equivalents (TE)/g extract,respectively). Phytochemical determination showed that C. cilicica water extract (17.26 mg rutin equivalents (RE)/g extract)was rich in flavonoids compared with ethyl acetate and methanol extracts (2.78 and 2.83 mg RE/g extract, for the respectiveextracts). These findings reveal the interesting potential of C. cilicica as a valuable source of phytochemicals that can be usedagainst common noncommunicable diseases, particularly against enzymes involved in neurodegenerative diseases.
