ABSTRACT
Objective:
To study the chemical constituents of flavonoids in the pine needles of Cedrus deodara.Methods:
Flavonoids were isolated and purified from ethyl acetate extract of the pine needles by chromatography on silica gel and Sephadex LH-20. Their structures were identified on the basis of spectroscopic analysis and chemical evidence.Results:
Five flavonoids were isolated and identified as 3′,5′-dimethoxymyricetin-3-O-(6″-O-acetyl)- α-D-glucopyranoside (1), myricetin (2), 2R,3R-dihydromyricetin (3), quercetin (4), and 2R,3R-dihydroquercetin (5).Conclusion:
Compound 1 is a new compound named as cedrusone A. Compounds 2-5 are isolated from the pine needles in the plants of Cedrus Trew for the first time.
