Objective: Diabetes is a long term condition which indicates the high blood pressure. The symptoms indicates, polyuria (frequent urination), they will become increasingly thirsty (polydipsia) and hungry (polyphagia). Many drugs has been discovered for curing diabetes. Recent studies reported that the administration of astaxanthin reduces the blood pressure in the diabetic patient. Astaxanthin is a powerful antioxidant found in wide variety of aquatic living organism which has wide applications in pharmacological studies.Methods: In vitro antidiabetic study of both encapsulated and non-encapsulated astaxanthin such as DNSA method, starch-iodine color assay method and α glycosidase enzymes assay was carried out.Results: The results of the present study indicated that both encapsulated and non-encapsulated astaxanthin shows higher antidiabetic activity in all the method. Each test samples possess the best activity when compared to standard drug acarbose.Conclusion: The present study, it is concluded that both non-encapsulated and encapsulated astaxanthin exhibit good antidiabetic activity.

The bacterium-to-plant signal, lipo-chitooligosaccharides (LCOs) or Nod factor induces cell division and enhances seed germination. The experiment was conducted to test the efficacy of LCO on soybean seed germination and seedling growth under room temperature by roll towel method. Different concentrations of LCO were used for seed treatment along with microbial inoculum and biocontrol agents as a control. Among the treatments, concentration of LCO @ 1.8 and 3.6 ml/kg of seed performed better compared to other treatments. The results revealed that treating with LCO could influence soybean seed germination and growth of seedlings.

In the present study, analysis of in vitro inflammatory showed whole plant of Rhizophora mucronata Lam. (Malpighiales: Rhizophoraceae) can be the potent source. The data from this study showed that the R. mucronata leaf, bark and root extract could serve as an important anti-inflammatory agent. Moreover, among the three extracts, the stilt root and leaves extract showed highest anti inflammatory. In vitro antiinflammatory activity of the selected plant extracts was evaluated using albumin denaturation, membrane stabilization and proteinase inhibitory assays. As part of the investigation on the mechanism of the anti-inflammation activity, ability of extract protein denaturation was studied. Maximum inhibition (296.26%) was observed from root extract followed by bark (259.48%) and leaf (237.62%). The extracts inhibited the heat induced hemolysis of RBCs to varying degree as show in table below. The maximum inhibition 284.17% was observed from bark extract followed by root (265.05%) and leaf (232.61%). It reveals that these phytochemical constituents are responsible to maximum protection of protein denaturation, albumin denaturation and membrane stabilization assay. The future work will be determination of anti-inflammatory and antiarthritic activities by in vivo models.

Allelopathic effect of Parthenium hysterophorus L. was studied on seed germination and seedling growth of two pulse crops (Vigna radiata (L.) R. Wilczek and Vigna mungo (L.) Hepper) and one oil seed crop (Arachis hypogea L.). The concentrations used were 20 g L -1 , 30 g L -1 and 50 g L -1 leaf extract of Parthenium hysterophorus. Seed germination of greengram was completely inhibited at 30 g L -1 leaf extract of Parthenium hysterophorus but in blackgram and ground nut, failure of seed germination was recorded only at 50 g L-1 leaf extract. The seed germination, plumule, radicle length and total biomass production were reduced with increasing concentration of aqueous solution. The study concluded that increasing concentration of leaf extract of Parthenium hysterophorus has adverse effect on germination, radicle length, plumule length and biomass production of Vigna radiata followed by Vigna mungo and Arachis hypogea than the control. The leaf extract has strong inhibitory effect on radicle growth than the plumule growth. The tolerance level of parthenium allelopathy of crops represented as Groundnut > Blackgram > Greengram.

: An experiment was conducted to study the effect of biostimulant, NovoBac on seedling characters of cowpea using roll towel method. The results observed from the study revealed that seed treatment with NovoBac @ 1g/kg has higher shoot length, root length, dry matter production and vigour index when compared with control. The increase was due to the effect of bacteria in NovoBac which produce growth hormones influence growth activities of cowpea.
