Two new myricetin glycosides from pine needles of Cedrus deodara.

Two new myricetin glycosides, myricetin-3- O-(6″- O- E- p-coumaroyl)- α- D-glucocopyranoside ( 1) and 3′,5′-di- O-methylmyricetin-3- O-(6″- O-acetyl)- α-D-glucopyranoside ( 2), and three known flavonoids, myricetin ( 3), cedrin ( 4), and 2 R,3 R-dihydromyricetin ( 5), were isolated from the pine needles of Cedrus deodara. Their structures were elucidated on the basis of extensive spectroscopic analysis and chemical evidence. [ABSTRACT FROM AUTHOR]
