Abstract: The present invention provides a pharmaceutical composition for treating bacterial infections in patients comprising an effective amount of 3.5-dihydroxy-4-pent-4′-enoyl-1′-oxymethylbenzoic acid (Oenostacin) isolated from Oenothera biennis.

Abstract: The invention provides a rapid in vitro method for selection of menthol rich mint genotypes from a large population of independent clones, said method comprising the steps of (i) raising a heterogeneous population of Mentha arvensis clones in vitro or by vegetative methods, (ii) transferring the plantlets/shoots to a basal medium, containing cytotoxic compounds in an amount sufficient to cause toxic effect in more than 95% of the clones, (iii) selecting surviving clones, their hardening in the glasshouse, transfer to field, reconfirmation of menthol tolerance through repeated in vitro assays, and (iv) multiplying selected clones and confirming genetic uniformity through RAPD analysis.

Abstract: This invention is related to the development of strategic and novel composition comprising &agr; arteether and nalidixic acid or quinolone drugs, said composition useful as an advanced generation drug to counter the resistance development itself and having a potential to be used in treating infectious diseases and in inhibiting the resistance developed due to mutation in the gyr A gene of bacteria, particularly in those cases where drug resistant strains are known to appear very frequently.

Abstract: The present invention is related to a method of producing organogenetic tissues from a plant of the genus Mentha, said method comprising the steps of culturing an explant from a plant of genus Mentha on an initiation medium in the presence of 400 to 600 lux light at a temperature of 23-27° C., with 16 hours of photoperiod, to obtain calli, transferring the calli to a basal medium comprising minerals and vitamins to ensure development of shoots, and culturing the shoots in a medium substantially free of growth hormones and containing menthol in a concentration of about 80 &mgr;g ml−1 to ensure root formation.

Abstract: Novel formulation useful in the treatment of drug resistant bacterial infections comprising an effective amount of ‘Thymol’ obtained from the plant Trychyspermum ammi, combination of mint oil containing appropriate amounts of monoterpene obtained from Mentha spicata and Mentha arvensis and obtaining conventional additives, a method for producing the formulation by mixing the above ingredients and a method for the treatment of drug resistant in a patient by administration of a therapeutically effective amount of the said formulation.

Abstract: The present invention provides a novel synergistic composition comprising extract obtained from the plant Albizzia lebbeck together with Bacillus thuringiensis &dgr;-endotoxin, useful in controlling lepidopteran insects, methods for the preparation of the composition and application of the insecticidal composition to standing crops.

Abstract: The present invention relates to use .alpha.-arteether as a antibacterial agent, preferably for gyr mutant bacteria which are resistant to quinolone drugs and can be used as therapeutic agents for treating drug resistant bacterial infections, and also as a antifungal agent.
