Absorption spectra of whole white tea extract and a sub-fraction of less than 1000 Da. Black line = water blank, Red line = white tea fraction < 1000 Da, Lilac line = whole white tea. Tea and fraction samples diluted to 25% of final concentrations used in bactericidal assays. Absorbance below 275 nm and from 375 nm to 900 nm not shown.
