Objectives: To investigate anti-inflammatory activity of Delonix elata (D.elata) leaf, by carrageenan induced paw edema and cotton pellet granuloma models, along with the antioxidant potential underpinning its role as traditional medicine for joint disorders. Materials and methods: Methanol extract and its, ethyl acetate soluble and insoluble daughter fractions were evaluated for anti-inflammatory activity. Rats were divided into seven groups (n=6), including control and standard. Oral doses of methanol extract (100, 200 and 300mg/kg) and its daughter fractions (300mg/kg) were given to animals after carrageenan challenge. The best performing methanol extract was forwarded for cotton-pellet induced granuloma model. The same was also subjected to antioxidant assays like DPPH free radical scavenging activity, reducing power assay and nitric oxide scavenging activity. Moreover, isolation and HPTLC quantification of a marker compound was also attended from methanol extract derived ethyl acetate fraction. Results: In comparison to control, methanol extract of D. elata leaf at 300 mg/kg showed significant reduction in area under curve of rat paw edema in the later phases of inflammation (45.83%), which was comparable to that of standard (valdecoxib, 33.525%). The extract was also effective in producing 28.125% inhibition of granuloma formation which was comparable to that of standard (23.88%). Apart from nitric oxide scavenging assay (IC50 157.08μg/ml), the activity of methanol extract in other assays were not as significant as the respective standard drugs. Of the ethyl acetate soluble and insoluble fractions evaluated, both showed marginal reduction in paw edema. From the ethyl acetate fraction, luteolin was isolated as a marker compound and quantified by HPTLC. Conclusion: Methanol extract of D. elata leaf was found to be active in the last phase of paw edema at 300 mg/kg, compared to other doses and fractions. At the same dose it was found to have potent antioxidant capacity, which may play its role in reducing inflammation. The claims regarding anti-inflammatory activity of D. elata leaf can be considered valid as explicated by its methanol extract.Keywords

A field experiment was carried out using twenty genotypes of cowpea [Vigna unguiculata (L.) walp] at Rajasthan College of Agriculture, Udaipur during 2008-09 treated with two Bradyrhizobium strains. Association studies revealed that seed yield per plant showed significant positive co-rrelation with pods per plant in all the environments, biological yield (E1 and E2), harvest index (E1 and E3), protein content (E3), days to maturity, nodule fresh weight and nitrogen content in (E3), most of these characters were also mutually correlated. Path analysis studies for seed yield revealed direct and indirect contribution of biological yield, harvest index, branches per plant, plant height and number of nodules (E1), pods per plant, nodule fresh weight, protein content and nodule dry weight (E2), nodule dry weight, branches per plant, protein content and plant height (E3). While the protein content revealed direct as well as indirect contribution of biological yield, number of nodules, harvest index, 100 seed weight and nodule fresh weight (E1), number of nodules, seed yield per plant, leghaemoglobin content and nitrogen content in (E2), seed yield per plant, harvest index, number of nodules and nodule fresh weight in (E3).Keywords

The present investigation consisted of 45 hybrids alongwith 18 parents and four checks viz., Arawali Makka-1, Mahi Kanchan, Navjot and PEHM-2 a total 67 entries was conduted during Kharif 2002 in Randomised Block Design having three replications. The data were recorded on fourteen traits to study general and specific combining ability effects. In general inbred lines L1, L3, L11 and L15 were considered good general combiner for yield and yield contributing traits as well as for quality traits. Among the testers, the tester T2 was considered good general combiner for maturity traits, plant type traits, harvest index and starch content. Majority of the hybrids exhibited significant positive values for yield and yield contributing traits as well as quality traits. Thereby, indicating that for these traits the genes with positive effects were dominent. The variance due to lines was of greater magnitude than that of testers for most of the traits. The ratio of 62sca/62gca indicated prependerance of non-additive variance for most of the traits. Parental lines L1, L3, L11 and L15 were found to be good general combiners for grain yield per plant as well as for other traits. Hybrid L12x T1 exhibited maximum significant positive sca effects for grain yield per plant. While the hybrid L2 x T1 exhibited highest estimates of significant positive sca effects for starch content. In general, there is a close association between sca effects, relative heterosis and per se performance for grain yield per plant was observed among the best hybrid identified on the basis of sca effects.Keywords
