The results showed that the total amount of phenolic compounds of white <em>chrysanthemum</em> extracted with ethanol 95 percent concentration was highest is 343.40 ± 6.88 mg equivalent of gallic acid per gram of dry weight. In the other hand, the type of solvent does not affect the content of phenolic compounds of yellow <em>chrysanthemum</em> flowers. Extraction of yellow and white <em>chrysanthemum</em> flowers with ethanol resulted in a higher content of flavonoids than distilled water extracts, equivalent to 455.75 ± 12.38 and 441.92 ± 43.59 mg equivalent of catechin per gram dry weight, respectively. The extract has been found to be a good antioxidant by exhibit strong free radicals scavenging namely, 2,2-Diphenyl-1-picrylhydrazyl (DPPH) equal to 197.04 ± 1.57 mg equivalent of vitamin C per gram dry weight. In addition, the <em>Chrysanthemum</em> extracts can reduce iron that can accelerate oxidation and were not significant (<em>p</em>>0.01). The knowledge obtained can be used for optimization the conditions for extracting <em>Chrysanthemum</em> flowers in order to obtain both the quantity and quality of the substances that need to be applied in medical and commercial uses.</p>}, number={1}, journal={Health Science, Science and Technology Reviews}, author={Ruenwai, Rawisara}, year={2020}, month={Apr.}, pages={16–20} }
