An O-acylated flavonoid glycoside from the needles ofPicea koraiensis

Summary 1. The needles of the Koyama spruce have yielded a new acylated flavonoid glycoside for which the structure of 3,4,5,7-tetrahydroxyflavone 3-O--L-(2-O-p-coumaroylarabinofuranoside) has been established.2. The structure of juglanin (kaempferol 3--L-arabinoside) has been refined as kaempferol 3-O--L-arabinofuranoside.Irkutsk Institute of Organic Chemistry, Siberian Branch of the Academy of Sciences of the USSR.
