jatrophone and Mouth-Diseases

The present study was designed to isolate and evaluate the antibacterial activity of the compounds from the whole plant of Euphorbia helioscopia L.. Various chromatographic techniques were used to isolate and purify the compound. The structure of the compound was elucidated on basis of spectral data ((1)H NMR, (13)C NMR, (1)H-(1)H COSY, HSQC, HMBC, NOESY, IR, and HR-ESI-MS). A new jatrophone-type diterpenoid (14α,15β-diacetoxy-3β-benzoyloxy-7β-nicotinoyloxy-9-oxo-jatropha-5E,11E-diene), named euphoheliosnoid E (1), was isolated from the whole plant of E. helioscopia L. Compound 1 showed significant anti-microbial activity against oral pathogens.
