ABSTRACT
Objective: To study the non-alkaloids from the 70% ethanolic extracts of Phellodendri Cortex. Methods: A variety of 732 cation exchange resin chromatography, D101 macroporous adsorbent resin chromatography, silica gel chromatography, ODS column chromatography, Sephadex LH-20 chromatography, and preparative HPLC methods were used for the separation and purification of chemical composition. Their structures were established on the basis of physicochemical properties and spectral analysis. Results: Fourteen compounds were identified as (-)-3-O-feruloylquinic acid methyl ester (1), (-)-4-O-feruloylquinic acid methyl ester (2), (-)-chlorogenic acid methyl ester (3), (-)-5-O-feruloylquinic acid methyl ester (4), salidroside (5), methyl ferulate (6), caffeic acid methyl ester (7), p-hydroxylbenzyl ethanol (8), 3,4,5-trimetoxyphenol-O-β-D-glucopy ranoside (9), 2-methoxy-4- (2-propenyl) phenyl β-D-glucopyranoside (10), tachinoside (11), methyl syringate (12), (6S)-dehydrovomifoliol (13), and (6R,7aR)- epiloliolide (14). Conclusion: Compounds 9-14 are isolated from the plants in this genus for the first time.
