Abstract: Sixteen compounds were isolated from the EtOH extracts of the branches of Dipteronia dyeriana. Based on spectroscopic methods, they were identified as erythro-4,7,9-trihydroxy-3,3′-dimethoxy-8-O-4′-neolignan -9′-O-β-D-glucopyranoside (1), hyuganoside IIIa (2), hyuganoside IIIb (3), erythro-buddlenol B (4), erythro-7′,8′-didehydrobuddlenol B (5), (±)-syringaresinol (6), cleomiscosin A (7), citroside A (8), (4R)-p-menth-1-ene-7,8-diol 7-O-?-D-glucopyranoside (9), 2-methoxy-3-(3-indolyl)propanoic acid (10), inosine (11), tachioside (12), isotachioside (13), 3-O-(β-D-glucopyranosyl)-1-(3,5-dimethoxy-4-hydroxyphenyl) -1-propanone (14),trans-isoconiferin (15) and 4-[(E)-3-ethoxyprop-1-enyl]-2-methoxyphenol (16). Compound 5 was a new sesquilignan, while other compounds were obtained from the genus for the first time.
