Abstract

Artemisia cina is one of the members of Compositae family that have been identified to display antimicrobial activity. This study aims to examine the ability of wild-type A. cina (KJT genotype) and its polyploid mutant (J genotype) in inhibiting the growth of Gram-positive and Gram-negative bacteria as well as to determine the concentration of kaemferol, quercetin, and artemisinin as secondary metabolites. Antibacterial activity was tested using Gram-negative bacteria (Escherichia coli and Pseudomonas aeruginosa) and Gram-positive bacteria (Bacillus subtilis and Staphylococcus aureus). The test of antibacterial activity was conducted using a disk diffusion method with 25, 50, 75 and 100% extract concentrations. Kaemferol, quercetin, and artemisinin contents were measured using High-Performance Liquid Chromatography. The extracts of both KJT and J genotypes indicated an inhibition on Gram-negative and Gram-positive bacteria growth. The antibacterial activity of both polyploid mutant (J) and wild type (KJT) genotypes was showed insignificantly different. The largest bacterial activity was observed in J genotype extract at 50% concentration against B. subtilis with a diameter of inhibition of 14.3 ± 0,60 mm. J genotype extract also showed a higher kaemferol, quercetin and artemisinin concentration compared to KJT genotype.
