Abstract: Two new phenylpropanetriol glycosides, named as meliadanoside A (3-methoxy-5-hydroxy-9-(l’-O-β-D-glucopyranosyl)-threo-phenylpropanetriol)and meliadanoside B(4-hydroxy-7,8-(2’,1’-O-β-D-glucopyranosyl)-phenylpropanetriol), were isolated from the water-soluble extract of the fruits of Melia toosendan Sieb. et Zucc., along with threo-guaiacylglycerol. Their structures were elucidated by spectroscopic and chemical analysis.

Key words: Melia toosendan, Meliaceae, phenylpropanetriol glycosides, meliadanoside A, meliadanoside B, threo-guaiacylglycerol
