Abstract: The present invention provides a novel pharmaceutical composition consisting of a combination of three coumarinolignoids of formula 1, 2 and 3 isolated from the seeds of the plant Cleome viscosa along with a pharmaceutically acceptable carrier useful as a immunomodulator. The invention also describes the ability of the compounds to modulate humorral and cell mediated immune response. It further provides a process for the preparation of a novel pharmaceutical composition of the said three coumarinolignoids in an optimized ratio to modulate humorral and cell mediated immune response.

Abstract: The invention provides a simple method for isolation of calliterpenone (16?,17 dihydroxy-3-oxo phyllocladane), a phyllocladane diterpenoid with the plant growth regulating properties, from plant genus Callicarpa.

Abstract: The present invention is related to the development of a novel, distinct high herb and artemisinin yielding genotype of Artemisia annua obtained through systematic marker assisted breeding followed by selection of uniform population in a methodical way wherein the genotype is distinct, uniform and stably maintainable by continuous rouging of off types in the population using DNA marker at early seedling stage from nursery itself and suitable for commercial cultivation.

Abstract: The present invention provides a novel process for the preparation of bacosides enriched fraction in a non-hygroscopic form the extract of Bacopa monniera, the said process comprising the steps of drying freshly harvested herb in a hot air oven at 37-42° C.

Abstract: The present invention relates to an improved method for the preparation of Artemether. Artemether prepared from the process is useful for the treatment of uncomplicated, severe complicated and multi drug resistant malaria.

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.

Abstract: The invention relates to a novel process for the isolation of a hepatoprotective agent Silymarin from the seeds of the plant Silybum marianum comprising (i) Precooling the seeds to (−) 20° C. for 24 hours in a deep freezer/cold room. (ii) Powdering the cooled seeds in a hammer mill, fitted with about 40 mesh discharge screen. (iii) Defatting the seeds by extracting with hexane in a soxhlet type extractor to remove the total quantity of fatty oil without using a scrain. (iv) Extracting the defatted seeds with acetonitrile at 20-30° C. to extract silymarin fraction. (v) Concentration of the sensitive silymarin fraction under vacuum in a agitated wiped thin film evaporator (vi) stirring the silymarin such dry powder with cold dichloromethane at 5° C. followed by filtration and drying with a slow purge of nitrogen gas. (vii) Further purification of silymarin by suspending in 5 times its weight of acetonitrile and precipitating by 8-12 times its weight of water at 20° C.

Abstract: This invention relates to a novel process for the dual production of essential oil and artemisinin from the plant Artemisia annua, said process comprising extracting the plant with hexane, partitioning the hexane extract between hexane and acetonitrile, hydrodistillation of hexane residue and Marc to yield essential oil, further fractionation of acetonitrile solvent between hexane-benzene mixture to remove artemisinic acid, chromatographing of the acetonitrile phase to produce substantially pure artemisinin, the artemisinic acid is reduced to obtain dihydro artemisinic acid which is then oxidised in a single step to form artemisinin.
