Citrullus colocynthis, belonging to the family of cucurbitaceae. It is a xerophytic desert plant, widely used for its medicinal purpose. In tribal areas it is used for the treatment of constipation, oedema, bacterial infection, cancer, diabetes and abortifacient. Present study is based on developing a protocol for plantlet regeneration from the nodal segment. The sterilized explants were inoculated in different concentrations of cytokinins and auxins. Among the various treatments, MS (1962) medium supplemented with BAP (2.0mg/l) gave the best shooting culture establishment. For shoot elongation MS medium supplemented with IBA (0.1 mg/l) was found to be best. In vitro elongated shoots rooted on MS medium supplemented with IBA (0.1 mg/l). The plantlets were hardened, acclimatized and transplanted in the field, where they showed 60% survival...

The chemical composition of the essential oil of Hyptis suaveolens (L.) leaves from three different regions of Tamil Nadu was analysed by GC – MS method and the constituents of three different localities were compared. In all 12 compounds were identified and they were α-caryophyllene, α-pinene, α-thujene, camphene, D-limonene, sabinene, β-myrcene, 1, 8-cineole, γ-terpinene, α-terpinolene, α-terpineol, phenentherene. It was found that the constituents of the essential oil differed in quantities in the three different populations of Hyptis suaveolens (L.) which may due to local geographical...

In this study, Pleurotus platypus and Pleurotus eous was subjected to identification of bioactive compounds by using Gas chromatography – Mass spectrum technique. These two organisms were extracted with 99% of ethanol. Extracted sample was injected, according to the retention time and peak formation the bioactive compounds are screened. In Pleurotus platypus Pyridine-3-carboxamide, 4-dimethylamino-N-(2, 4-difluorophenyl), Piperidin-4-carboxylic acid, Aspidofractinine-3-methanol, (2à, 3á, 5à), Indolizine, and 2-(4-methylphenyl)-. Pleurotus eous shows that Imidazolidine, 1, 3-dinitro, Phenol, 2-methyl-4-(1, 1, 3, 3-tetramethylbutyl), Aspidofractinine-3-methanol, (2à, 3á, 5à) and Squalene. Pleurotus platypus and Pleurotus eous were subjected to analysis the water soluble – Vitamin B and Fat soluble vitamin A, D, E and K was analysed in High Performance Liquid Chromatography technique. According to the results P.platypus shows the high content of vitamin E and...

A Sustained release tablet formulation should ideally have a proper release profile that is usually encountered in manufacturing. The objective of the present investigation was to develop the sustained release matrix tablet of Boswellia serrata, Moringa oleifera and Vitex negundo using the combination of hydrophilic and hydrophobic polymers.Tablet formulations were developed using wet granulation method. Ethanolic extracts of Boswellia serrata, Moringa oleifera and Vitex negundo were used. Addition of different diluents like talc , magnesium stearate and microcrystalline cellulose were used for improving flow ability and compressibility. The tablets were subjected to physicochemical characterization, in vitro drug release and stability studies. The physicochemical properties were found within limits. The % drug release after 12 hours for formulation F-1, F-2, F-3 was found to be 97.32, 90.12, and 73.85 respectively. The presence of Ethyl cellulose as well as HPMC as the total matrix material significantly influenced the release rate of the drug. Based on dissolution studies all the formulations showed sustained release of drugs from the...
