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-α-L-(2″-O-p-coumaroylarabinofuranoside) has been established.
2. The structure of juglanin (kaempferol 3-α-L-arabinoside) has been refined as kaempferol 3-O-α-L-arabinofuranoside.
