Reliability of leased out area reported under the household ownership holding distributions of the National Sample Survey is doubtful. It suffers from significant negative bias due to underreporting of tenancy by landlords. The degree of bias was found to vary substantially across the states for 1981-82 (37th Round). The author argues that its variation over the ownership size class, too, must be unequal and therefore warns against an elaborate analysis of leased out area statistics.
More important is the implication of direct and significant relationship of the size of negative bias with the value of output per hectare and incidence of rural poverty. Indeed, in areas with high concentration of tenancy and poverty, growth in informal tenancy has been distressingly high.

High Performance Thin layer chromatography tandem mass spectrometry (HPTLC-MS) method was developed and validated for the determination of Terconazole in biological matrix. HPTLC-MS is rapid and economic technique for the appropriate identification and quantitation of active pharmaceutical ingredient in various matrices. Terconazole showed Rf value 0.65±0.018 using Toluene: Ethyl Acetate: Methanol (6:2:2 v/v/v) as mobile phase. Linearity was obtained within concentration range 50-300ng/band with regression coefficient 0.9921. The proposed method showed percentage recovery 99.4±0.8% and % RSD 0.852, verifying that the method is accurate and precise. The recovery after application to biological matrix was 98.1±1.2% proving its applicability to routine use. LOD and LOQ were 11.5 ng/band and 34.9 ng/band respectively. Specificity study showed that the components of biological matrix did not interfere with the analyte, thereby confirming the specificity of the method. Mass spectrometry was resulted in the spectrum showing mass peak at 531.8 m/z. HPTLC-MS method resulted in direct identification and structural characterization of the analytes from the TLC plate which seems to be convenient as well as less time consuming and thus illustrating wide applicability.Keywords

Bio-efficacy of Aureofungin-sol, an antifungal antibiotic, for control of downy mildew and powdery mildew of grape was evaluated during October 2008 - April 2009 fruiting season in vineyards at three locations in Maharashtra. Four to nine sprays of Aureofungin-sol, @ 0.108, 0.163 and 0.217 g/l, starting from 12-16 days to 46-75 days after fruit pruning gave good control of downy mildew on leaves and bunches, and increased harvestable yield over the Control. Similarly, four sprays of Aureofungin-sol @ 0.108 g/l at 11 to 20 days' interval at 65 days after pruning provided complete control of powdery mildew on leaves and bunches. No residue of Aureofungin-sol was found in harvest samples above the limit of detection (0.1 mg/kg).Keywords

The present study deals with UV spectrophotometric method development and Validation for estimation of Tizanidine and Aceclofenac in bulk drug and tablet dosage form by absorption correction by interference method. The method is based on by using two wavelengths, 274 nm for aceclofenac and 318 nm for Tizanidine. The Linearity of Tizanidine and Aceclofenac was found to be in the range 0f 2-10 μg/ml and 5-25 μg/ml respectively. The % recovery of Tizanidine and Aceclofenac was found out to be 98-102 % respectively. The proposed method was validated as per ICH guidelines.Keywords

In current study, 2,4,5-trisubstituted-1H-imidazoles have been synthesized by starting from acid chloride preparation of various aromatic acetic acids (Ar’) such as 1-naphthyl acetic acid and 4-biphenyl acetic acid, which are used as such for the Friedel–Craft acylation (FCA) using various substituted aromatic nucleus (1a-b) (Ar) such as anisole, thioanisole etc and anhydrous aluminium trichloride to get various ethanone derivatives (2c-d). Methylsulfanyl group is converted into methylsulfonyl by refluxing former with glacial acetic acid and hydrogen peroxide to get ethanone derivatives containing methylsulfonyl moiety (2e-f). These ethanone derivatives (2a-f) were subjected to microwave irradiation for 90 secs to obtain diketones or ethanediones (3a-f). Ethanediones, in presence of acetic acid, ammonium acetate and benzaldehyde offered targeted compounds (4a-f). The structural elucidation of synthesized compounds was done using IR as well as 1H NMR spectroscopy and biological screening for antibacterial action using E. coli and S. aureus and antifungal action using C. albicans and C. fumigatus was done using cup plate agar diffusion method.
