Chemical investigation of the roots of Viburnum dilatatum Thunb resulted in the isolation and characterization of a new phenolic glycosides 2-(-glucopyranosyloxy)-benzyl 3-(-glucopyranosyloxy)-benzoate (1), together with two known compounds. Their structures were established by spectroscopic means
The fruit of Viburnum dilatatum Thunb., called gamazumi, has been shown to prevent oxidative injury in rats given gamazumi crude extract (GCE). Therefore, phenolic compounds in GCE were purified by Sephadex LH-20 column chromatography and preparative high-performance liquid chromatography. Two major
Chemical investigation of the fruit of Viburnum dilatatum Thunb resulted in the isolation and characterization of a new phenolic glycoside (1), to which the name jiamizioside E was assigned. Its structure was established by chemical and spectroscopic means.
This study aimed to evaluate the antioxidant activity of various plant extracts. A total of 94 kinds of edible plant extracts obtained from the Korea Plant Extract Bank were screened for cytotoxicity, following which the total phenolic content of 24 shortlisted extracts was determined. Of these,
