T. laurifolia is a medicinal plant that is most widely
distributed in the northern part of Thailand. Major
compounds of T. laurifolia are apigenin, caffeic acid,
flavonoids and chlorophyll derivatives which exhibit
antioxidant properties. T. laurifolia extract demonstrates
antioxidant properties both in vitro and in vivo. It is able to
reduce OS-induced pathology by increasing endogenous
antioxidant system and reducing oxidation reaction of
macromolecules such as lipid. Therefore, supplementation
of T. laurifolia is one of the important approaches to
prevent OS-related pathology.
