METHODS
Chemical constituents were isolated by the repeated chromatography methods and their structures were identified by spectral analysis.
RESULTS
Five compounds were obtained as follows: 3-O-[beta-D-xylopyranosyl-(1-->2)-beta-D-fucopyranosyl-(1-->6)-beta-D-glucopyranosyl]-21-O-(6S)-2-trans-2-hydroxy-methyl-6-methyl-6-O-beta-D-quinovopyranosyl-2,7- octadienoyl-acacic acid-28 -O-beta-D-glucopyran -osyl(1-->3)-[alpha-L-arabinofuranosyl (1-->4)]-alpha-L-rhamnopyranosyl(1-->2)]-beta-D- glucopyranosyl ester (1). acacigenin B (2) julibrotriterpenoidal lactone A (3) machaerinic acid lactone (4) acacic acid methylester (5).
CONCLUSIONS
Compound 1 was isolated directly from this plant for the first time.
