In this article we will discuss about the tests for the detection of alkaloids in plants with the help of experiment. The alkaloids are a group of basic, secondary plant substance, which usually possess a N-containing hetero-cycle. Their basic character is due to this feature. The alkaloids are mostly colourless, crystalline and non-volatile solids. They are insoluble in water, but [...]
Data essential for different ecological characterization of a vegetation or a plant community needs detailed survey of the area. A preliminary survey or reconnaissance precedes intensive work in any particular area. During the primary survey of a vegetation the following criteria are generally observed: 1. Distribution of different communities and such other ecological groups, 2. Different climatic, edaphic and topographic [...]
Enzymes are thermo-labile organic catalysts which are very much sensitive to heat and pH. The activity of a number of respiratory enzymes could be detected within plant tissue by suitable tests. (a) Detection of Dehydrogenase: This enzyme accomplishes intracellular oxidation and reduction by the transfer of hydrogen from one type of molecule to another. The importance of such enzyme is [...]
