title: Antimicrobial and cytotoxic phenolic glycoside esters from the New Zealand tree Toronia toru.
abstract: Two new compounds, 4-hydroxyphenyl 6-O-(4-hydroxy-2-methylenebutanoyl)-beta-D-glycopyranoside (1) and 4-hydroxyphenyl 6-O-[(3R)-3,4-dihydroxy-2-methylenebutanoyl]-beta-D-glucopyranosid e (2), have been isolated from foliage of Toronia toru. Compound 2 was the main antimicrobial component (7 mg/g of dry foliage) of the crude extract and also showed significant cytotoxic activity against P-388 leukemia cells.
