A new flavanone, a new prenylflavone, a novel phenolic compound, heter
ophylol, reported in a previous paper, and nine known flavonoids have
been isolated from the root of Artocarpus heterophyllus. The two new f
lavonoids have been characterized as 5,2'-dihydroxy-7,4'-dimethyoxyfla
vanone and imethylallyl)-5,2',4'-trihydroxy-7-methoxyflavone, respecti
vely.
