Objective:
To study the chemical constituents of the roots of Capparis tenera.
Method:
The chemical constituents were isolated and repeatedly purified by kinds of column chromatography and the structures were elucidated by the NMR spectra and physicochemical properties.
Result:
Eight compounds were isolated and identified as erigeside C (1), glucosuringic acid (2), vanillic acid 4-O-beta-D-glucoside (3-methoxy 4-glucosyl-benzoic acid) (3), 4-O-beta-D-glucopyranosylbenzoate (4), 3', 5'-dimethoxy- 4-O-beta-D-glucopyranosyl-cinnamic acid (5), tachioside (6), 2, 3-dihydroxy-1-(4-hydroxyl-3, 5-dimethoxyphenyl)-1-propanone (7) and acacetin 7-rutinoside (8).
Conclusion:
Compounds 1-8 were all isolated from this plant for the first time and the compound 8 was isolated from this gene for the first time.
