摘要: Abstract (−)- cis -2,3-Dihydroquercetin (presumably as the 3′- O -β- d -glucopyranoside); - -glucopyranosides of (+)- trans -2,3-dihydroquercetin, dihydromyricetin and eriodictyol; (+)-catechin (+)-gallocatechin have been isolated from needles Pinus sylvestris . The dihydroquercetin aglycones interconvert in methanolic solution. Two chemotypes can be distinguished on basis their dihydroquercetin, eriodictyol contents.
