  • Patent number: 9018226
    Abstract: The present invention relates to bioactive extracts its fractions and isolation of compound from Rauwolfia tetraphylla. The extracts and fractions are useful for the treatment of psychosis based on in-vivo validation on animal model and proportional binding affinities for dopaminergic-D2, Cholinergic (muscarinic) and Serotonergic (5HT2A) receptors for antipsychotic activity. The present invention relates to novel antipsychotic activity in the leaf alkaloids of Formula 1 and 2 named tetrahydroalstonine, 10-methoxytetrahydroalstonine, isoreserpiline, 10-demethoxyreserpiline, 11-demethoxyreserpiline, reserpiline and ?-yohimbine. The present invention also relates to processes for obtaining antipsychotic extracts as well as for the isolation of alkaloids of formula 1 and 2 from the leaves of Rauwolfia tetraphylla. The present invention particularly relates to significant antipsychotic activity in the MeOH extract, ethylacetate and chloroform fractions of R.
