[Studies on chemical constituents of Ranunculus ternatus].
OBJECTIVE
To study the active constituents of Ranunculus ternatus.


METHODS
The constituents were isolated with silica gel and Sephadex LH -20 gel column chromatography and purified by HPLC. Their structures were elucidated by spectroscopy.


RESULTS
Sixteen compounds were obtained and identified as Stigmasta4, 6, 8 (14), 22-tetraen-3-one (1), 5-hydroxymethyl furaldehyde (2), gamma-keto-delta-valerolactone (3), pantolactone (4), 5-hydroxymethyl-dihydro-furan-2-one (5), methyl 5-hydroxy-4-oxopentanoate (6), methyl hydrogen succinate (7), succinic acid monoethyl ester (8), 3, 4-dihydroxybenzoic acid methyl ester (9), p-hydroxycinnamic acid (10), 4-oxo-pentanoic acid (11), succinic acid (12), nonanedioic acid (13), 4-hydroxybenzoic acid (14), 4-hydroxybenzaldehyde (15), stigmasterol-3-O-beta-D-glucopyranoside (16).


CONCLUSIONS
Compound 1, 4 -15 are obtained from this plant for the first time.
