The objective of this study was to elucidate the phytochemical, antioxidant and antimicrobial activities of Protorhus longifolia seed extracts in vitro. The phytochemical analysis revealed the presence of flavonoids, glycosides and sterols predominately in the methanol and ethanol extracts. Antioxidant activities were evaluated in vitro by DPPH-radical scavenging, H2O2 and ABTS+ assays.

Rice blast is continues to be the major constraint in sustainable rice production throughout the world. Although many genetic resources harboring single R-genes are available for blast resistance, wide genetic variations exist in the blast fungus lead to breakdown of these resistant varieties soon after its release. To control such a deadly disease, there is a need to identify QTLs which offer durable partial resistance.

Enzymes are biocatalysts that govern life processes. Each biochemical reaction of cell metabolism is catalyzed by one specific enzyme. Enzymes can catalyze reactions in different states but most commercial enzymes, being water soluble are difficult to recover at the end of the catalytic process. This restricts the use of soluble enzymes to essentially batch-operations followed by disposal of these expensive enzymes containing solution. A possible approach to resolve this problem is to attach enzymes onto a solid/ semi solid support material.

Economically feasible, sustainable and nonpolluting ways for ethanol production has become important due to limited petroleum supply and associated environmental consequences of burning fossil fuel. Three experimental lignocellulosic materials viz., Hyptis suaveolens, wheat straw and Ailanthus exelsa wood were taken to subject them to dilute acid pretreatment in presence of selected metals. Metals Zn and Ca were found general inhibitors of release of hemicellulosic sugars. A.

Gum Arabic is believed to have many health benefits including prevention of gastrointestinal diseases. Prebiotic resist digestion in the upper gastrointestinal tract and allowed for stimulation of bacterial growth in the distal intestine and colon. The prebiotic properties of Acacia Senegal was studied using mixed cultures of human fecal bacteria from four lean individuals. The results obtained were compared with inulin as positive prebiotic control.

Plantlet regeneration methods through somatic embryogenesis were standardized from stem explants of Euphorbia hirta in this report. The explants were surface sterilized with 0.1% (w/v) mercuric chloride solution. The sterilized explants were inoculated on MS (Murashige and Skoog) medium to induce somatic embryos. The explants with somatic embryos were transferred to the embryo germination and shoots elongation medium.

Etodolac is a nonsteroidal anti-inflammatory drug, which result in inhibition of the enzyme cyclooxygenase (COX). The aim of this study is to formulate and evaluate oral disintegrating tablets (ODTs) of etodolac to achieve rapid dissolution, absorption and further improving the bioavailability of the drug. The oral disintegrating tablets were prepared by using Croscarmellose sodium, Sodium starch glycolate and Crospovidone by direct compression method. Taste masking was done by flavouring agents.

Superdisintegrants, etodolac, antiinflammatory, and flavouring agents.

Plant health and other parameters are dependent on plant growth promoting (PGP) abilities which are further dependent on the microflora in the plant rhizospheric soil. In this study both the sterile and non-sterile soils of Dehradun were taken for the PGP and the seeds of Cicer arietinum were taken for the vigour index with the treatment of NKA1 (phosphate solubilizer).

Keywords: 
PGP, Cicer arietinum L., Vigor index, Enzyme activity.
