Samples were extracted from the petals with water and ethanol and antioxidative and antimicrobial activity was assessed.Determination was also made of extract content, color, pH, α-tocopherol content and absorption spectra. The antioxidative activity of the water extracts showed the following order : red petals >white petals >yellow petals >purple petals >pink petals, and in the ethanol extracts : purple petal=yellow petals >white petals >red petals. The water and ethanol extracts were antibiotic to essentially the same extent.Read More
