Anti-inflammatory activity of commiphora caudata [Wight and Arn]

Ethyl acetate and methanolic extracts of Commiphora caudata syn: Protium caudatum were tested for anti-inflammatory activity in rats by carrageenan-induced hind paw oedema method. Both ethyl acetate extract and methanolic extract of Commiphora caudata [200 mg/kg of body weight] exhibited significant anti-inflammatory activity when compared with control. Indomethacin was used as a reference anti-inflammatory drug

Evaluation of antibacterial activity, phenol and flavonoid contacts of thespesia populnea flower extracts

Flavonoids which were reported as having many pharmacological activities, antimicrobial, antioxidant, cytotoxic, chemoprevention activities and they possess strong antiproliferative effects related to inhibition of cell cycle progression and apoptosis induction. On the basis of this Thespesia populnea [L.] Sol. Ex Correa [Family-Malvaceae] was selected and it is having the major composition of flavonoids and the antibacterial activity of methanolic extract of Thespesia populnea flowers was investigated by agar well diffusion method. Furthermore our phytochemical studies indicated that methanolic extract of Thespesia populnea flowers contains flavonoids, alkaloids, tannins and anthroquinone glycosides. Moreover the individual components were identified by thin layer chromatography and Rf value was compared with standard flavonoid quercetin. The total phenolic and flavonoid content studies were also quantified. The bacteria used for antibacterial study were Shigella flexneri [NCIM 4924], Rhodococcus terrae [NCIM 5126], Escherichiae coli [ATCC 11775], Streptococcus faecalis [NCIB 2406], Klebsiella pneumoniae [ATCC 13883],Brevibacterium luteum [NCIM 2923], Micrococcus flavum [NCIM 2376], Proteus mirabilis [NCIB 8268], Bacillus licheniformis [NCIM 2468], Micrococcus luteus [ATCC 2984], Flavobacterium devorans [NCIM 2581], Shigella sonei[ATCC 29930], Shigella boydii [ATCC 8700] and Shigella dysentriae [ATCC 13313].According to our results in the lowest tested concentration of 62.5microg/ml and 125microg/ml 7.2% of the plant extract were active, 5% active in the concentration of 250microg/ml, 75.7% active in the concentration of 500microg/ml and 92.8% active at the concentration of 1000microg/ml in a dose dependent manner

Investigation on three different species of Wedelia from Tamilnadu and Andaman Nicobar Islands

Comparative studies on three different species of Wedelia from Tamilnadu and Andaman Nicobar Islands have been carried out for their growth performance, Active constituents, Preliminary phytochemical screening of entire plants, extraction of essential oil, extractive values, [alcohol and water soluble]. Ash values [Total ash, Acid insoluble ash, Sulphated ash, water and insoluble ash]. Microscopical evaluation [like vein islet and vein termination number, stomatal number, stomatal index] and fluorescence analysis were also performed
