To determine in vitro anti-aging activity and identify the active chemical constituents in Ginkgo leaf extracts. The antioxidant properties of Ginkgo biloba leaves extracts were evaluated using 1,1-diphenyl-2-picrylhydrazyl radical (DPPH) scavenging and 2,2'-azino-bis (3-ethylbenzothiazoline)-6 sulfonic acid radical (ABTS) scavenging assays. The inhibitory effects of extracts and chemical constituents on reactive oxygen species, matrix metalloproteinase- 1 (MMP-1) and collagen tpye I level were tested using human dermal fibroblasts (HDFs). Reverse-phase liquid chromatography (RPLC) and ultra-performance liquid chromatography tandem mass spectroscopy (UPLC/MS/MS) were used to quantitatively analyze flavonoids and terpene trilactones in the extraction. The established quantitative analysis method was validated according to the regulatory guidelines. The extraction and compounds kaempferol 3-O-beta-D-glucopyranoside, isorhamnetin-3-O-glucoside, myricetin, ginkgolide A and bilobalide could have potential anti-aging activities of G. biloba. The results suggest that G. biloba could be used as anti-aging products and as a cosmetic and medicinal raw material.
