Abstract

The genus Iris
L. (Iridaceae) is a member of geophytes with attractive flowers. There are about 56 Iris taxa
growing in Turkey, 24 of which are endemic. A survey of the literature
indicates that the research carried out on Iris species are focused on
the flavonoid and volatile compounds of the plant.

In present study, the dichloromethane and
methanol extracts prepared from the rhizomes of 47 Iris taxa growing in
Turkey were investigated for their in vitro cholinesterase inhibitory
effects against acetylcholinesterase (AChE) and
butyrylcholinesterase (BChE) which the enzymes linked to Alzheimer’s diseases and antioxidant capacities using 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical
scavenging test as well.

The Iris extracts studied have been found
more active against BChE than AChE. compared
with 100
μg/ml galanthamine (89.29 ± 0.96 %) as reference, Iris kerneriana (coded as Y122) and Iris pseudacorus (coded as Y131)
methanol extracts had significant BChE inhibition effect (respectively, 80.22 ±
1.04 % and 53.06 ± 1.13 %) at concentration of 200 μg/ml. Among
tested samples, methanol extracts of I.
kerneriana, I. lazica, I. pseudacorus and I. suaveolens have shown remarkable antioxidant activity at
concentration of 2 mg/ml for DPPH compared with gallic acid.
