  • 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.

  • Patent number: 6337095
    Abstract: The invention relates to a process for the isolation of compound scopoletin which is used as nitric oxide synthesis inhibitor from Artemisia annua and other plant families, said process comprising extraction of dried powdered material of different plant parts with an aqueous acetonitrite solvent in the ratio of 1:5 for 6 to 8 hrs., concentration of the extracted solvent upto 30% of its original extract under vacuum, partitioning the concentrated extract with halogenated solvent to transfer scopoletin in the non-polar halogenated solvent, drying halogenated solvent over anhydrous sodium sulphate and evaporating the solvent, crystallizing the residues in methanol and filtering the crystals, concentrating the filtrate and chromatographed on silica gel, eluting scopoletin in chloroform methanol mixture; and crystallization of the fractions containing the scopoletin to get the pure scopoletin compound.
