Phenolic compounds and different biological activities of the dry MeOH 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 antioxid...ant 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.
