Several reports are available for Rhododendron arboreum which is limited to its subspecies nilagiricum. The present study intended to examine the bioactive compounds and the antimicrobial activity of leaf extracts of R. arboreum Sm spp. nilagiricum (Zenker) Tagg against medically important four bacterial (Streptococcus pyogene, Staphylococcus aureus, Escherichia coli, Klebsiella pneumonia) and two fungal (Candida albicans and Trichoderma viride) strains. Agar well diffusion method is applied to assess the antimicrobial activity of the aqueous and methanol extracts of the plant sample. Various fractions of aqueous, ethanol, methanol and chloroform extracts confirmed the presence of alkaloids, phenols, flavonoids, tannins, saponins, terpenoids, steroids, carbohydrates, glycosides, amino acids, and proteins. The methanol extract of leaf revealed a promising antibacterial and antifungal activity against S. aureus and T. viride respectively. This study shows a broad and great therapeutic potential of the leaf extract. However further studies are necessary for this potent leaf extracts to evaluate the other parameters of antimicrobial...

The present investigation deals with the in-vivo and in-vitro mast cell stabilizing the activity of fruits of Terminalia chebula ethyl acetate and methanol extracts at 500 mg/kg body weight. In egg albumin induced degranulation studies, Kitotifen as a standard was found to inhibit degranulation to an extent of 80.12%, where as ethyl acetate and methanolic extracts inhibited degranulation to 58.98% and 44.56% respectively similarly in compound 48/80 induced mast cell degranulation in rats ethyl acetate and methanol extracts of Terminalia chebula and standard Kitotifen showed the following percentage inhibition of degranulation of mast cell 40.28%, 51.19% and 75.12 respectively. In in-vivo study ethyl acetate and methanolic extracts at the dose of 500 mg/kg bodyweight inhibited degranulation of mast cell to the extent of 46.5 % and 37.33%...

The stem of Spermadictyon suaveolens Roxb. (Rubiaceae) was evaluated for its pharmacognostic characteristics. The stem was assessed for its macroscopic, organoleptic, microscopic and phytochemical characters. The macroscopic study revealed variation in color of the stem when fresh and dried. The macroscopic evaluation was studied with parameters viz. color, odor, shape, and surface in fresh and dry condition. Quantitative microscopical data of wood elements as well as stomatal index studied through standard procedures. Total ash, acid insoluble ash, percentage extractives and fluorescence analysis in addition tannin, flavonoid, alkaloid, saponin in the alcoholic extract of stem powder recorded during an investigation. The quantitative estimation of protein, carbohydrate and oil was carried out by different scientific denoted methods. In the propagation study through the stem, cutting showed maximum percent sprouting in the treatment IAA 100 ppm (65%) and maximum percent survival in the treatment IAA 100 ppm (60%) followed by IAA 50 ppm (42%). Antioxidant assay by using Superoxide Dismutase showed positive results 96.7% in dark...

The present study deals with the qualitative and quantitative analysis of phytochemical and proximate analysis of seed extract of two different germplasms of Mucuna black and white colored seeds (BCS & WCS) were investigated. Between the two seeds studied, the black colored seed which is in raw form registered higher efficiency in proximate composition as well as phytochemical when compared to white colored seeds. This consequence has followed the same in both cooked and soaked & cooking process of Mucuna seeds. Further, mechanistic studies on pharmacological evaluation are needed for commercial exploitation of these legumes as...

The crude extracts from stem tuber and leaf of Brassica oleracea var. gongylodes in different solvents, were subjected to physicochemical, fluorescence analysis, phytochemical and antimicrobial study. The microscopic analysis revealed that B. oleracea showed stone cells and calcium oxalate prisms. The ash value was high 7.88 % in B. Oleracea. The fluorescent analysis at 366 nm of B. oleracea under ultraviolet light revealed that powder extracted with alcohol showed pale blue colored fluorescence, with water showed yellow color, 0.1 N Sodium hydroxide showed pale yellow and dilute hydrochloric acid had greenish yellow. The extraction value with different solvents exhibited that B. oleracea maximum extractive value with chloroform followed by benzene, ethanol and petroleum ether. The phytochemical screening of the various extract of B. oleracea revealed the presence of alkaloids, flavonoids, resins, saponins, and tannins. Anti-bacterial screening in B. oleracea using stem revealed that the ethanol solvent showed maximum inhibition against gram-positive bacteria (Staphylococcus aureus) and chloroform solvent showed maximum inhibition in the case of gram-negative bacteria (Serratia...
