A phytochemical investigation on the leaves of Cistus parviflorus led to the isolation of 18 compounds. The structures of the isolated compounds were elucidated as kaempferol 3-O-(3′′,6′′-di-O-E-p-coumaroyl)-β-D-glucopyranoside (1), scopoletin (2),kaempferol 3-O-(3′′-O-E-p-coumaroyl)-β-D-glucopyranoside (3), kaempferol 3-O-(6′′-O-E-p-coumaroyl)-β-D-glucopyranoside (4), kaempferol 3-O-β-D-glucopyranoside (5), kaempferol 3-O-α-L-rhamnopyranosyl-(1→2)-(6′′-O-E-p-coumaroyl)-β-D-glucopyranoside (6), methyl flavogallonate(7), quercetin 3-O-β-D-glucopyranoside (8), quercetin 3-O-β-D-galactopyranoside (9), hydroquinone (10), arbutin (11), methyl β-glucopyranoside (12), shikimic acid (13), (S)-1,2-propandiol-1-O-β-D-glucopyranoside (14), benzyl-O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside (15), 2-phenethyl-O-α-L-rhamnopyranosyl-(1→6)-β-D-glucopyranoside (16), corchoionoside C (17), kaempferol 3-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside (18) by the analysis of the MS and NMR spectroscopic data and comparison with the literature. Compounds 1–2, 6–7, 10–12, and 14–16 were isolated from Cistus genus for the first time.
