[Studies on chemical constituents from root of Clematis hexapetala].

OBJECTIVE: To study the chemical constituents from the roots and rhizomes of Clematis hexapetala. METHOD: The compounds were separated by means of solvent extraction, repeated chromatography with silica gel and HPLC. The structures were determined by spectral analysis. RESULT: Nine compounds were isolated as friedelin (1) , anemonin (2) , beta-sitosterol (3) , palmitic acid (4) , vanillic acid (5) , isolariciresinol (6) , 5-hydroxumethyl-5H-furan-2-one (7) , n-nonane (8) , daucosterol (9). CONCLUSION: All the compounds were isolated from the plant for the first time.
