| Objective To study the chemical constituents of the stems of Gordonia chrysandra. Methods The chemical constituents were isolated and purified by column chromatography on silica gel, MPLC and PHPLC. Their structures were elucidated on the basis of physicochemical properties and special analysis. Results Five compounds were isolated from the stems of G. chrysandra and elucidated as 3,4-dimethoxyphenol 1-O-β-D-[6-O-(4-hydroxy-3,5-dimethoxylbenzoate)-glucopyranoside (1), 3,4,5-trimethoxyphenyl-6-O-vanilloyl-β-D-glucoside (2), 2α,3β,19α-trihydroxyolean-12-en-23,28-dioic acid (3), betulinic acid (4), 3-O-β-D-galactopyranosyl-(1→2)-[β-D-glucopyranosyl-(1→2)-α-L-arabinopyranosyl-(1→3)]-β-D-glucuronopyranosyl-3β,16α,22α,28-tetrahydroxy-22-O-tigloyloxy-olean-12-ene-23-al (5). Conclusion Compound 1 is a new compound named chrysandroside A, and compounds 3-5 are isolated from this plant for the first time. |
