Objective To study the chemical constituents from the stems and leaves of Tamarix chinensis. Methods The compounds were isolated and purified by silica gel, Sephadex LH-20, ODS column chromatography, and their structures were identified on the basis of physicochemical properties and spectroscopic analysis. Results Fifteen compounds were isolated and identified as tamarixetin-7-O-β-D-glucoside (1), tamarixetin-3-O-α-L-rhamnoside (2), rutin (3), 5, 7, 3', 5'-tetrahydroxy-6, 4'-dimethoxyflavone (4), quercetin-7, 3', 4'-trimethyl ether (5), kaempferol-3-O-β-D-glucuronide (6), apigenin (7), rhamnocitrin (8), kaempferol (9), quercetin (10), tamarixetin (11), betulinic acid (12), 2α, 3β-dihydroxy-urs-12-en-28-oic acid (13), β-amyrin acetate (14), and 2α, 3β, 23- trihydroxyolean-12-ene (15). Conclusion Compounds 1—7 and 13—15 are isolated from this plant for the first time, and compounds 13 and 15 are isolated from this genus for the first time.
