Antibacterial Activity of Senkyunolide A Isolated from Cnidium Officinale Extract.

In this study, we investigated the antibacterial and anti-inflammatory properties of Cnidium officinale hexane (COH) extract and senkyunolide A (SA). The antibacterial activities were measured using the paper disk diffusion method and minimum inhibitory concentration (MIC) against Propionibacterium acnes and Malassezia furfur. COH extract showed antibacterial activity at a concentration of 50 mg ml^-1. The MICs of COH and SA were determined using the broth microdilution method. COH was found to be active on all the bacteria tested (10 ≤ MIC ≤ 20 mg ml^-1). SA showed antibacterial activity against P. acnes. The anti-inflammatory properties were determined using a pancreatic lipase inhibition activity method, lipoxygenase inhibition activity, and inhibition of nitric oxide production activity. COH and SA inhibited the production of nitric oxide by up to 50 µg ml^-1 in a dose-dependent manner. COH and SA possess antibacterial and anti-inflammatory activities. They could be used as antibacterial ingredients in various industries.
