Abstract:
OBJECTIVE: To study the chemical constituents of Syringae Cortex. METHODS: The compounds were isolated and purified by silica (200-300), pre-HPLC and Sephadex LH-20 column chromatography. The structures were identified on the basis of spectral data and physiochemical properties. RESULTS: Twelve compounds were isolated and identified as syringin(I), sinapylal-dehyde 4-O-β-D-glucopyranoside(II), syringaldehyde(III), coniferyl aldehyde(IV), betulinic acid(V), oleuroprin(VI), oleoside dimethyl ester(VII), ligstroside(VIII), 2″-epifraxamoside (DC), β-sitosterol(X), n-triaconatanoic acid(XI) and 2-(4-hydroxyphe-nyl)-ethyl-l-dodecyloctadecanoate) (XII). CONCLUSION: Compounds II-V, VII and XI-XII are isolated from this plant for the first time.
