Physiological and Anti-microbial Activities of Extract from Spray Chrysanthemum (Dendranthema grandiflorum) Petals

This study was conducted to use the various aspects of spray chrysanthemum. Petals of spray chrysanthemum ‘Geumbangeul’, ‘Magic Ball’ and ‘Pink Pangpang’ were harvested and extracted through hot water and ethanol methods to examine their physiological activities. For hot water extract method, total phenolic compound contents of the ‘Geumbangeul’, ‘Magic Ball’ and ‘Pink Pangpang’ petals were 100.1, 52.9 and 66.4mgㆍL⁻¹, respectively. However, total phenolic compound contents of the ‘Magic Ball’, ‘Pink Pangpang’ and ‘Geumbangeul’ by ethanol extract method were 95.7, 65.1 and 49.4mgㆍL⁻¹, respectively. Total flavonoid contents of the ‘Pink Pangpang’ through hot water extract method was 45.7mgㆍL⁻¹, and of the ‘Magic Ball’ through ethanol extract method was 54.0mgㆍL⁻¹. DPPH radical scavenging activity of ‘Magic Ball’ petal extract by both hot water and ethanol extract methods showed to decreasing pattern. ‘Magic Ball’ had the highest anti-microbial activity against the gram-positive strain of Bacillus subtilis and the gram-negative strain of Salmonella enteritidis. In conclusion, petal extract of spray chrysanthemum ‘Magic Ball’ had good physiological and anti-microbial activities. Further research is needed to investigate different physiological activities among spray chrysanthemum cultivars.
