ABSTRACT
silica gel column chromatography, Sephadex LH-20 gel column chromatography, medium pressure column chromatography, high pressure flash chromatography, and semi-preparative HPLC, and their structures were elucidated on the basis of physico-chemical constants and spectral analysis. Results: Fourteen compounds were identified as syringin (1), 3, 4-dihydroxyphenyl ethanol (2), oleuropein (3), salidroside (4), oleoside 11-methyl ester (5), (8E)-nuezhenide (6), (8Z)-ligstroside (7), oleoacteoside (8), oleoside dimethyl ester (9), olivil-4'-O-β-D-glucoside (10), (+)-cyclo-olivil-6-O-β-D-glucoside (11), (+)-cyclo-olivil-4'-O-β-D-glucoside (12), ligstroside (13), and wilfordiol B (14). Conclusion: Compounds 2, 4, and 12-14 are obtained from this genus for the first time, and compounds 1, 3, and 5-11 are obtained from this plant for the first time.
