Abstract:
Wedelia calen-dulacea Less. (Asteraceae) is well known for its antibacterial, demulcent and antifebrile properties, it is a traditional medicine which wild growing in many areas in Viet Nam. The researchers firstly study its chemical composition. Results of the chemical analysis show that: The plant contains flavonoid, alcaloids, coumarin, triterpenoid saponins, tanin, sugars, fat, sterols and carotenoid. The content of total flavonoids is about 1% (on dry basis), at least 11 spots on chromatogram. The content of total saponins is about 12% (on dry basis). The analysis with 3 different solvent systems revealed at least 15 spots on chromatogram. Some of the spots can be shown with both flavonoid and coumarin reagents, these are tentatively called coumestan components.
