A rapid and accurate method is described for the determination of diosgenin in Dioscorea conzposita roots. After acid hydrolysis and solvent extraction of the root, pure diosgenin is isolated by thin-layer chromatography, treated with sulphuric acid methanol, and the resultant chromophore is measured by spectrophotometry. Similarly, gas liquid chromatography is used to evaluate statistically th...

This study was carried out in the Tarai region of Uttarakhand, India to estimate carbon stock and sequestration potential Dalbergia latifolia Melia composita plantations different ages (4 6 years old). A total 14 regression equations using one variable, dbh (diameter at breast height), were primarily selected for both tree species component-wise. Tree density 880 960 individuals ha−1 D. M. mono...
