Inferred pH means pH calculated from straight and cation conductivity. The calculation can be applied to condensate, feedwater, and boiler water. Although not widely used in the United States, inferred pH is popular in Europe. Some plant chemists find inferred pH useful because it eliminates the need to measure pH directly, which without proper equipment can be a difficult task. This paper disc...
Although the hybrid discipline of biochemical systematics has been a distinct field of study for only about ten years, it has had a telling impact on taxonomic practice. Nevertheless, the chemical approach, with its emphasis on the exact, tends to exlude much of the wealth of natural phenomena that are the backbone of taxonomy. It is necessary for the chemist and biochemist to acquire a better ...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

Based on research to date, we can state some expectations about terrestrial ecosystem response as several elements of global climate change develop in coming decades. Higher plant species will vary considerably in their response to elevated UV-B radiation, but the most common general effects are reductions in height of plants, decreased shoot mass if ozone reduction is severe, increased quantit...

Barton, F.E., II, 1988. Chemistry of lignocellulose: methods of analysis and consequences of structure. Anita. Feed Sci. Technol., 21: 279-286. Historically, the chemistry of lignocellulose has been the chemistry of the extraction, solvolysis, hydrolysis and analysis of cellulose and lignin from plant material. The analyses used to determine their relative content are empirical, i.e., the value...
