Brine shrimp lethality bioassay of selected Centaurea L. species (Asteraceae)
Abstract
Ether extracts of 15 Centaurea L. species (Asteraceae) methanol extracts of 12species, and cnicin isolated from C. derventana were tested for general bioactivity using the brine shrimp lethality test. Cnicin showed the most potent activity with LC50 0.2. Also, ether extract of C. splendens showed significant activity with LC50 7.3, as did methanol extract of C. arenaria with LC50 12.4.
