According to a study published by "Chemistry & biodiversity", the leaves of Engelhardia roxburgiana Wall. are widely used to develop herbal teas in southeast of China for medicinal use against diabetes mellitus and hyperlipidemia. Chemical analysis of the total flavonoids of Engelhardia roxburgiana leaves (TFER) revealed 10 components, 7 of which acted as active ingredients. These 7 active ingredients include naringenin, kaempferol, quercetin, isoengeletin, engeletin, astilbin and quercitrin. The study utilized Apoe-/- mice to demonstrate that TFER reduced atherosclerotic plaque size in the aorta and significantly decreased serum lipids. Furthermore, the treatment down-regulated the expressions of NF-κB p65 subunit, TNF-α, VCAM-1, and IL-1β in the thoracic aorta.
