Abstract
Phenolic
compounds and different biological activities of the dry methanol
extracts of the flowers and the herb (aerial parts without flowers) of
Laserpitium zernyi Hayek (Apiaceae) were investigated. The total
phenolic contents in the extracts were determined spectrophotometrically
using Folin-Ciocalteu reagent. In both extracts, apigenin, luteolin,
their 7-O-glucosides and chlorogenic acid were detected by HPLC.
Identified phenolics were quantified in both extracts, except luteolin
in L. zernyi herb extract. The extracts (p.o.) were tested for
anti-edematous activity in a model of carrageenan (i.pl.) induced rat
paw edema. Antioxidant activity of the extracts was assessed by FRAP
assay and DPPH and 'OH radicals scavenging tests. Antimicrobial activity
was investigated using broth microdilution test against five
Gram-positive and three Gram-negative bacteria, as well as against two
strains of Candida albicans. The polyphenol-richer flower extract
exerted higher anti-edematous and antioxidant activities. The herb
extract exhibited better antimicrobial effect against Micrococcus
luteus, Enterococcus faecalis, Bacillus subtilis and Pseudomonas
aeruginosa, while against other tested microorganisms the activity of
both extracts was identical. Demonstrated biological activities of L.
zernyi flower and herb extracts represent a good basis for their further
investigation as potential new herbal medicinal raw materials. This article is protected by copyright. All rights reserved.
