AbstractOur final instalment in the debate with Jim Kincaid argues that his value-analysis suffers from weaknesses associated with both Ricardian and Rubinesque (mis-)interpretations of Marx. These approaches are methodologically flawed, because value-theory does not draw upon externally imposed theories or standards of logic or evidence to check the conceptual or empirical validity of its approach to the understanding of capitalism. Rather, Marxian value-theory involves reconstructing in thought the class-based production-processes underpinning capitalism through to their more complex and concrete consequences in the broader economic and social structures, agencies and processes, through which they are formed, albeit with definite effects of their own. Examination of the methodological shortcomings in Kincaid's analysis is followed by specific rebuttals of his claims about the (qualitative and quantitative) determination of value and price, the circulation of capital, the role of competition, fixed capital, productive labour and the leverage of value-theory in informing empirical studies.

AbstractA new method is described for the qualitative and quantitative determination of both free and bound maleic hydrazide residues in tobacco leaves and cigarette filler by high performance liquid chromatography. Analyses were carried out by hydrolyzing samples of ground tobacco with 4 N hydrochloric acid for 40 minutes under reflux followed by sample chromatography, running isocratic elutions with a dilute solution of phosphoric acid. The quantitative determination of maleic hydrazide was performed by light absorption at 320 nm, by the calibration curve method. Recoveries of maleic hydrazide added to tobacco samples were greater than 90 %. The detection limit of the method, determined on ground tobacco leaves, was at least 5 ppm. The results obtained by this procedure and by the ISO standard method no. 4876 are in good accordance.

The present enquiry was intended to analyze the phytochemicals qualitatively and quantitatively from flowers of Spanish cherry tree. Flower powder was extracted using polar and nonpolar solvent by soxhlet apparatus. Percentage yield of crude extracts was determined and further the extracts were subjected to analyze the phytochemicals qualitatively and quantitatively by standard procedure. Qualitative analysis showed the absence of alkaloids while presences of tannins, saponins, terpenoids, steroids, glycosides, flavonoids, phenols. Quantitative estimation of phytochemicals was determined using standard curve. Result revealed that the tannin content was 4.3±0.01 (mgTAE /gm), flavanols content was 0.28±0.05 (mgQE/gm). Saponins content was 3.6±0.7 % and terpenoids content was 1.47±0.37 %. A well conducted studies on phytochemicals revealed that they are vital for humans because they provide protection against a variety of ailments. Therefore, the present study is aimed to analyze phytochemicals qualitatively and quantitatively. Keywords: Phytochemicals, Tannins, Saponins, Flavanols, Terpenoids
