Objective To study the chemical constituents in the leaves of Elaeagnus mollis. Methods Their structures were identified on the basis of silica gel column chromatography and Sephadex LH-20 gel column chromatography, and HPLC methods were used for the separation and purification of chemical constituents. Results Sixteen compounds were isolated from 70% ethanol extracts of the leaves of E. mollis. The structures were identified as kaempferol-3-O-β-D-glucopyranoside(1), kaempferol-3-O-(6"-O-trans-p-coumaroyl)-β-D-glucopyranoside(2), kaempferol-3-O-(6"-O-cis-p-coumaroyl)-β-D-glucopyranoside(3), quercetin-3-O-α-L-arabinopyranoside(4), kaempferol-7-O-α-L-rhamnopyranoside(5), kaempferol-3, 7-di-O-α-L-rhamnopyranoside(6), kaempferol-3-O-β-D-galactopyranosyl-7-O-α-L-rhamnopyranoside(7), kaempferol-3-O-α-Larabinofuranosyl-7-O-α-L-rhamnopyranoside(8), hippophamide(9), L-tryptophan(10), arjunolicacid(11), ursolicacid(12), kaempferol(13), rutin(14), adenosine(15), and β-daucosterol(16). Conclusion Compounds 3-10 and 15 are isolated from the plants of Elaeagnus L. for the first time. Compounds 1, 2, 11, and 12 are isolated from this plant for the first time.
