Two new phenylpropanoid derivatives and other constituents from Illicium simonsii active against oral microbial organisms.
Bioassay-guided fractionation of the ethanol extract of the leaves and stems of Illicium simonsii led to the isolation of two new compounds, simonin A (1) and 1-hydroxyl-2- O- β- D-6'-acetyl-glucopyranosyl-4-allylbenzene (2), along with eight known compounds. Their structures were elucidated by spectroscopic analysis. The isolates were tested for anti-oral microbial activity using a microdilution method. Compounds 1 and 3- 6 showed significant activities against oral microbial organisms (Actinomyces viscosus, Streptococcus mutans, Streptococcus sanguis, and Actinomyces naeslundii), with minimum inhibitory concentration (MIC) values ranging from 1.95 to 31.25 µg/mL in vitro.
