Chemical constituents in the roots of Evodia lepta(Spreng.) Merr(Ⅱ)

Silica gel column chromatography was used to isolate four known compounds from the ethyl acetate extracts of the roots of Evodia lepta(Spreng.) Merr, which were identified by spectral methods as (1) kokusaginine, (2) (trans)-3,4,5-trihydroxy-6-acetyl-7-methoxy-2,2-dimethylchroman, (3) skimmianine and (4) (trans)-3,4-dihydroxy-5-methoxy-6-acetyl-7-methoxy-2,2-dimethylchroman. All these compounds were isolated from the roots of Evodia lepta(Spreng.) Merr for the first time.
