The objective of this study was to report the
antioxidant activities of two varieties of Malaysian
pink guava. Selected flavonoid compounds were
quantified (apigenin, isorhamentin, kaempferol, luteolin,
myricetin, and quercetin). Various functions
and actions such as antioxidants and anticarcinogens
have been attributed to flavonoid compounds,
making determination of their concentrations in
food highly desirable.
