An experiment was carried out during Kharif season of 2010-2011 at plot no. 11, Main Garden, Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola, entitled seed yield of cowpea as influenced by nitrogen and phosphorus level under enceptisol conditions. An experiment was laid out in Factorial Randomized Block Design (FRBD) with sixteen treatment combinations and two factors with four levels of nitrogen viz., 0, 12.5, 25, 37.5 kg ha-1 and that of the phosphorus 0, 25, 50, and 75 kg ha-1 and replicated thrice. The results revealed that, plant height showed significant influence towards application of nitrogen 37.5 kg ha-1 in addition to phosphorus 25 kg ha-1. Main branches plant-1 were found maximum with an application of 25 kg nitrogen ha-1 and 75 kg phosphorus ha-1. The reproductive characters like days to 50 per cent flowering and days to first picking was recorded minimum with the application of 25 kg nitrogen ha-1 and 50 kg phosphorus ha-1. Seed yield and yield contributing characters like pod plant-1, and seed yield ha-1(q) were found significantly maximum, wherein application of 25 kg nitrogen ha-1 in addition to 75 kg phosphorus ha-1 was undertaken. As regards to the interaction effect, N2P2 treatment combination i.e. application of 25 kg nitrogen along with 50 kg phosphorus ha-1 reflected in the production of maximum seed yield of cowpea.Keywords

Achyranthes aspera is common weed found in India and has great medicinal importance. The plant is beneficial in various ailments including stomachache, piles, boils, skin eruption and in asthma. It is also used as anti-inflammatory and as immunomodulator drug. It may act on reactive oxygen species which are one of the factor in the pathogenesis of these diseases. Various extracts of A. aspera, viz., petroleum ether extract, chloroform extract, ethyl acetate extract, ethanol extract and aqueous extract were screened for the antioxidant activity of the plant by using DPPH assay, ABTS assay and FRAP assay. Among all these extracts petroleum ether extract was found to be active as it shows lowest IC50 value in DPPH assay and highest trolox equivalent antioxidant concentration (TEAC) in ABTS assay and FRAP assay. Phytochemical screening revealed that as flavonoids, tannins and phenolic compound are absent in the plant, nonpolar compounds like steroids may be responsible for the antioxidant activity of the plant.

This paper describes a new, simple, precise, and accurate HPTLC method for quantitation of andrographolide in kalmegh extract and its pharmaceutical dosage form. Chromatographic separation of the drugs was performed on aluminum plates precoated with silica gel 60 F254 as the stationary phase and the solvent system consisted of toluene:ethyl acetate:formic acid: methanol 50:30:05:2.5 (v/v/v/v). Densitometric evaluation of the separated zones was performed at 226 nm. The andrographolide was satisfactorily resolved with RF values of 0.34±0.03 in both plant extract and pharmaceutical dosage form. The accuracy and reliability of the method was assessed by evaluation of linearity (100-800 ng spot-1), precision (method precision RSD 1.52% and system precision RSD 1.38%), accuracy (97.34±1.47) and specificity in accordance with ICH guidelines.Keywords

Background: Excoecaria agallocha Linn. (Euphorbiaceae) is a small mangrove tree that grows widely in the tidal forests and coastal areas of India. Milky Mangrove is known to have antihyperglycemic, antimicrobial, anti-inflammatory and many other bioactivities. Aim: The present work aims to perform a comprehensive phytochemical and pharmacognostical study of Excoecaria agallocha Linn. Materials and Methods: The Pharmacognostical studies on Excoecaria agallocha including parameters such as morphological evaluation, microscopical evaluation, leaf constants, physicochemical parameters, Thin layer chromatography (TLC) and phytochemical studies were established. Result and Conclusion: Mean ash values (%) were 16.00 (total), 2.75 (acid insoluble), and 13.35 (water soluble). Loss on drying was 0.20%. Microscopy reveals dorsiventral leaf and presence of diacytic stomata in the leaf sample. Quantitative microscopical features such as Stomatal Index, Vein islet number, vein termination number and palisade ratio was determined. The report of TLC indicates presence of Alkaloids and flavonoids. Phytochemical study revealed the presence of alkaloids, steroids, flavonoids, terpenes, tannins and phenolic compounds. Conclusion: The results of the study can serve as a valuable resource of pharmacognostic and phytochemical information. Further work is needed to isolate, characterize, and quantify active constituents present in the leaves of Excoecaria agallocha Linn. by sophisticated techniques.Keywords
