Abstract

Corn silk has been found to be an excellent source of bioactive compound. Two novel flavone glycosides of corn silk were identified by means of spectral analyses as 2″-O-a-L-rhamnosyl-6-C-3″-deoxyglucosyl-3′-methoxyluteolin and 6,4′-dihydroxy- 3′-methoxyflavone -7-O-glucoside. Also, the flavonoid contents of 40 corn silk lines collected from 16 provinces in China were analyzed by high performance liquid chromatography and colorimetric methods.

 

Key words: Corn silk, flavonoids, isolation, chromatography, spectral analyses.
