Objective To study the chemical composition of the silver leaf tree Heritieralittoralis D. Methods Silica gel column chromatography was used for separation and purification, and the structures were identified by spectral analysis. Results Eight flavonoids were isolated and identified from the leaves of the silver leaf tree. They were quercitrin 1, quercetin 2, and kaempferol 3 O (6′′ OE p coumarin) β. D gluco pyranoside 3) (kaempferol 4), kaempferol 4 (kaempferol 4), kaempferitrin 5 (myricetin 6), eriodictyol 7 (eriodictyol 7) And catechin (catechin 8). Conclusion Compound 2-8 was isolated from this plant for the first time
