OBJECTIVE
To study the chemical constituents of Wedelia prostrata.
METHODS
Chromatography and spectroscopic analysis were employed to isolate and elucidate the chemical constituents in the plant.
RESULTS
Seven compounds were obtained and identified as ent-kaur-16-en-19-oic acid (I), ent-kaur-16alpha, 17-dihydroxy-19-oic acid (II), ent-kaur-15alpha-senecioyloxy-16-en-19-oic acid (III), beta-sitosterol (IV), stigmasterol (V), stigmasterol-3-O-beta-D-glucopyranoside (VI) and n-hexacosanol (VII).
CONCLUSIONS
Compounds I-III are isolated from this plant for the first time.
