Anti-inflammatory activity of ethanolic extract of cultured mycelia of four different species of the oyster mushroom, Pleurotus was examined. The activity was evaluated by carrageenan induced acute and formalin induced chronic models in mice. The extracts showed significant dose dependent inhibition of both acute and chronic inflammation and the activity was comparable to that of standard reference drug Diclofenac. The results thus indicated that mycelia of Pleurotus species possess significant anti-inflammatory activity. The findings also reveal the potential therapeutic value of the mycelium of Pleurotus species as anti-inflammatory agent.

The diffusates of Ipomoea ohiaincd from different parts and their combinations produced significant effect on germination and early seedling growth of paddy var. 5016. Among the diffusates tested at 50% and 100% level. Young Shooi-YS (T-2,), Flower-F + YS (T-1) and F + Leaf-L + YS (T-1) diffusates (D) of Ipomoea shows stimulatory (negative) allelopathic effect on seed germination and early seedling growth of paddy var. 5016. However all other diffusates of Ipomoea and treatments exhibit both stimulatory (negative) and inhibitory (positive) allelopathic effect. Maximum seed germination of 96% was favoured by the diffusates of L + YS and F + L + YS at 50% level in T-3. F + L diffusates (at 100% level) of Ipomoea increase the seedling growth to a maximum of 26.2 cm/pi in T-3 as compared to other diffusates and treatments. Higher Seedling Vigour Index-SVI (2482) and Seedling Tolerance Index-STl (1.45) of paddy seedling was recorded in T-3 (L + YS D at 50% level) and T-1 (F+LYS D at 50% level). respectively. Maximum biomass (fresh weight - 96mg/pl and dry weight - 19mg/pl) production was recorded in F + L and L diffusates of Ipomoea at 100% level in soil treatments (T-3).

Adv Pl Sci 2007, 20(1), 285-8.

Two greengram (Vigna radiata L. Wilczek) mutants of K-851 and B-l along with their respective parents inoculated with Bradyrhizobium strain M-10 to study their response to root-shoot characteristics and nitrogenase activity com-prised the experimental materials. Positive effects of Bradyrhizobial application in the soil was reflected by all the characters like 'root fresh weight', 'root dry weight', 'shoot fresh weight', 'shoot dry weight' and 'nodule volume' irrespective of varieties and their respective mutants. Bold grain mutant of K-851 had higher effective nodule number both in parent and Bradyrhizobium treated population as compared to control. Nitrogen fixing potential in terms of nitrogenase activity was recorded from the plants of inoculated and uninoculated bold grain mutant and uninoculated control. Higher nitrogenase activity could be observed in case of both the mutants and their parents than the uninoculated control. The bold grain mutant of K-851 had the highest nitrogenase activity as compared to K-851 and B-1 control as well as their mutants. As the mutant (K-851) had higher number of effective nodule and greater nodule volume and dry weight, better yield/plant is therefore corroborative. Thus there is a scope of selection of plants with higher nitrogen fixing capability following mutagenesis.

Relative effects of 8-Hydroxy Quinoline (8-HQ) on meiosis and pollen fertility were studied in Vicia faba L. var. major in M₁ generation. Meiotic studies revealed dose dependent decrease in chiasma frequency from 18.56 in control to 17.80 in 1.50% of 8-HQ at prophase-1 and from 17.76 in control to 16.92 in 1.50% of 8-HQ at Metaphase-1. The other meiotic aberrations observed were stickiness, laggards, univalents, multivalents, bridges, fragments, precocious separation etc. Stickiness of chromosomes was the most common aberration followed by precocious separation and laggards. Among the different stages of meiosis the frequency of chromosomal aberration was maximum at metaphase stage and showed dose dependent increase with the mutagen. Pollen sterility seems to be the cumulative result of various meiotic aberrations.

Extracts of the medicinal plants Glycyrrhiza glabra,L.and Holarrhena antidysenterica Wall neutralized stable DPPH (2,2diphenyl -1-picryl-hydrazyl) free radical and prevented hydroxyl radical induced damage to deoxyribose. The extracts protected supercoilled DNA of the plasmid pBR322 from gamma-radiation induced strand breaks as evidenced from studies on agarose gel electrophoresis of the plasmid DNA after radiation exposure. Exposure of liver homogenates to 25 Gy gamma-radiation in vitro resulted in peroxidative damage to membrane lipids. Presence of the extracts along with the homogenates protected lipids from peroxidative damage. Administration of the extracts (100uμg/kg body weight) p.o. to mice prior to whole body gamma-irradiation (4Gy) prevented radiation-induced peroxidation of lipids in liver tissue. The radioprotective property of the extracts has been attributed to the free radical scavenging and antioxidant activities.

Envir Ecol 2007, 25(2), 312-14.

Rumen fungus Orponomyces sp. was cultured anaerobically at 39 C in specified fungal media and morphological and metabolic characteristics were studied. Orponomyces sp was found as a polycentric fungus with globose or elongated oval sporangium that releases variable shaped poly flagellate zoospores upon bursting. The fungus was observed to produce higher amount of formate and acetate with lower proportion of lactate compared to monocentric fungus and absence of propionate, butyrate and other branched chain fatty acids production. The morphological and fermentation characteristics of Orpinomyces sp indicate that the fungus may have significant role in ruminants fed fibrous diets.

Biosci Biotechnol Res Asia 2007, 4(1), 19-22.

Roots of madder (Rubia tinctorum) are source of anthraquinone dyes with alizarin being the main component. Free alizarin (I) is present in madder root in only small quantities, most of it is present as its glycoside i.e. ruberythric acid(lll) On the basis of the importance of alizarin, in this research, it was isolated, purified and its structure was confirmed by various spectra. Maceration of the powdered madder roots in various polar and non-polar solvents, as well as Soxhlet extraction resulted in the formation of a reddish solid material (5.2% and 14.2% yield, respectively). Successive TLC and column chromatography of the solid material on silica gel with methanol as the mobile phase, gave three fractions with R₁ = 0.21, 0.48 and 0.68. The fraction with R₁ = 0.68 was the major one. 'HNMR, ¹³CNMR, IR, UV and Mass spectra of this fraction were taken. On the basis of the results obtained from the spectra, the chemical structure of alizarin was determined and confirmed.

Effective micropropagation protocol has been established to rapidly propagate Chinese foxglove R. angulata. Callus was successfully induced from the explants of hypocotyls on media containing 0.5 mg l^-1 BAP and 0.4 mg l^-1 NAA; and then adventitious shoots differentiated on the media supplemented with 1 mg l^-1 BAP and 0.5 mg l^-1 NAA at the initial stage. In shoot proliferation stage, a newly developed Formula β (A+B) based media was more effective than MS salts based media to induce new shoots by approximately regenerating twice as many shoots per explant, while the multiplication rate of roots was nearly three times higher in Formula β than in MS after eight-week culturing. There was no significant influence on the induction of shoots and roots between conventional culture plasticware and a new type of culture container made of high-density polyethylene bags. The roots were induced and formed in the multiplication media after eight weeks of culture before transplanting in the glasshouse and resulted in an efficient and simplified propagation procedure of in vitro culture integrated with white polythene material protection to give stronger and healthier transplantations at the acclimation stage.

Med Pl 2010, 2(2), 117-23.

Bitter gourd (Momordica charantia) is extensively cultivated in India, China and South East Asia for vegetable and traditional medicines. A severe yellow mosaic disease on bitter gourd (M. charantia) with a significant disease incidence was observed during the survey of different locations of Eastern U.P., India in the year 2007. The disease consisted of yellow mosaic accompanied with slight curling on leaves. The whitefly (Bemisia tabaci) population was also observed in the vicinity. The characteristic disease symptoms and whitefly population indicated the possibility of begomovirus infection. PCR was carried out using the total DNA isolated from infected leaf samples and a pair of begomovirus specific primers which resulted in the expected size (<126>800 bp) amplicon in 3/6 samples indicating presence of begomovirus. For further identification of the begomovirus, the PCR amplicons were cloned and sequenced (GenBank accession no. EU439260). The sequence data analysis revealed highest 98-93% similarities with several isolates of Tomato leaf curl New Delhi virus (ToLCNDV) at both nucleotide and amino acid levels. The phylogenetic analysis also showed closest relationships of the isolate (EU439260) with various variant of ToLCNDV. Based on highest sequence similarities and closest relationships with ToLCNDV the virus isolated from bitter gourd was considered as an isolate of Tomato leaf curl New Delhi virus.

Int J Sci Nat 2010, 1(1), 61-6.

Leaf morphological characteristics of woody species were examined in tropical rain forest at Kudremukh National Park in the central Western Ghats, India in relationship with ecological and environmental factors. For leaf size analysis, Raunkiaer leaf size classification was adopted. The data was collected from 114 sample plots of the size 31.6 x 31.6 m distributed randomly in the study area. In each plot the proportion of leaf size classes and other leaf morphological characters were calculated and correlated with the ecological and environmental data. A significant correlation of leaf morphological character with percentage evergreeness and in few instances with elevation and rainfall was obtained. Average leaf width decreased with increase in elevation. Mesophyll leaf class dominated the stand, whereas, leptophyll and nanophyll leaf classes are sparingly represented. Proportions of serrate and whorled leaves increased with increase in elevation. A significant effect of percentage evergreeness of the stand was found on leaf size and leaf morphological characters.

Med Pl 2010, 2(2), 97-102.

Flavonoid rutin (quercetin-3-rutinoside), is a flavonol glycoside comprised of the flavonol quercetin and the disaccharide rutinose. In the study, using HPLC-ED system, quantification of rutin was carried out in different extracts of medicinal plants. Analyses of rutin were performed with leaves and flowers of 50 medicinal plants of rue, buckwheat, rose, sage, calendula, chamomile, elder, dandelion, feverfew, lemon balm, linden, thyme, valerian, stinging nettle, cloves, dog rose, pansy, parsley, cowslip, rose etc. Rutin was extracted with hot water. Supernatant was used for analyses. The standard solution was 0.2 μg/20 μL rutin. Content of rutin (mg/g) was highest in the leaves of rue (86.0) followed by flowers of buckwheat (53.5), the leaves from buckwheat (20.0), flowers of pansy (33.5) and flowers of rose (10.0). In all other plants, the content of rutin was lower than 0.5 mg/g. The lowest content rutin (0.25 mg/g) was found in the leaves of lemon balm. The high concentration of rutin in flowers and leaves of rue, buckwheat, pansy and rose provided more importance to rue, buckwheat, pansy and rose as medicinal and diet plants.

Senescense is a puzzling process it always differs from ageing. It may or not be lead to death .it not only support the degradation process but also promote the growth of new plant parts. Physiological senescense is definitely followed by death while non-physiological not be followed. It is due to definenecy of any essential mineral. It is controlled by several factor, harmones are one of them. Auxin delays the senescense. Generally, higher concentrations of IAA used for visible symptoms of senescense were observed below lOOppm at very high concentration i.e. 400ppm, it becomes non-physiological in both intact and excised conditions. 300ppm of IAA shows maximum delay.

Med Pl 2010, 2(3), 205-14.

Bitter leaves of Nyctanthes arbor-tristis are used in traditional systems of medicines for the treatment of rheumatism, sciatica and intestinal worms. The study was to provide scientific backing to the traditional claims through the in vitro evaluation of the ethanolic, methanolic and aqueous leaf extracts for antioxidant, antibacterial and anticancer potentials. Antioxidant potential was tested by 2, 2-diphenyl-1-picryl-hydrazyl (DPPH) assay based free radical scavenging ability. The scavenging effect of leaf extract and ascorbic standard on the DPPH radical was found to be in the following order: Ascorbic acid<62> Ethanolic<62> Aqueous<62> Methanolic extracts and their IC₅₀ values were found to be 1.6 μg, 25 μg, 34 μg and 38 μg respectively. The antibacterial potential was tested against five strains each of Gram positive and Gram negative bacteria through agar disc diffusion assay. The results showed that the bactericidal potential was higher in aqueous extracts followed by methanolic and ethanolic extracts. The bacterial strains Salmonella typhimurium, Pseudomonas aeroginosa, Klebsiella pneumonia, Escherichia coli, Pseudomonas marginata and Staphylococcus epidermis were found to be more susceptible to the aqueous extract where Micrococcus leuteus, Staphylococcus aureus, Streptococcus pyogenes and Bacillus subtilis were more sensitive to the methanolic extract. The anticancer potential of the extracts was tested using MTT (3-(4,5dimethylthiazol-2-yl)-2,5- diphenyl tetrazolium bromide) based cytotoxic test on the T-cell leukemia (MOLT-4) cells at 24, 48 and 72 hours incubation. Simultaneously the growth inhibition potential of the extracts was tested on mitogen stimulated T-lymphocyte cultures derived from the peripheral blood of healthy individuals. All the extracts exhibited significantly higher cytotoxicity towards cancer cell with increasing time and dose, and at the same time there was a considerable decrease in the level of toxicity observed in normal cells at all the dose and time points. As a measure of genotoxic assessment, micronucleus assay was done in cancer and normal cultures exposed to increasing concentration of different extracts. In both cultures, there was a vast difference between the number of micronuclei induced by the extracts even at the highest tested concentration and the positive control. The results indicated that more elaborate study in this plant may lead to the discovery of new therapeutic agents.

Methanol extract of leaves of Mimosa pudica L. (Mimosaceae) was screened for diuretic and laxative activities in wistar albino rats. The study suggested that the extract was found to produce significant diuretic as well as laxative activities in dose dependant manner (200 and 400mg/kg p.o.). These activities were comparable with the standard drugs such as Furosemide (10mg/kg p.o.) and Agar-agar (300mg/kg p.o.) respectively. The preliminary phytochemical analysis of methanol extract of leaves of Mimosa pudica revealed the presence of phytoconstituents such as alkaloids, tannins, mucilage and flavonoids. The study indicates that the observed significant diuretic and laxative activities of Mimosa pudica leaves may be contributed to the phytoconstituents present in it.
