Introduction, for biological activity. There is a desire to find out more about the interactions between one organism and another which can be attributed to the chemical substances present in at least one of the species concerned. The area where activity has been greatest is the effect of extracts from the flowe作者: 同位素 時間: 2025-3-22 13:34
Important concepts,ned and ultimately the molecules responsible can be identified. These concepts are related to the molecular structure of all the components of the fractionation system and the environments to which they are subjected at different stages of the fractionation process.作者: 斜坡 時間: 2025-3-22 21:07
Methods for extraction and sample clean-up,testing in bioassays, for determining their structure, or both, the initial step clearly involves separating them from the cellular structural material (mostly protein, lipid and polysaccharide) and ideally from the large majority of unrelated substances coexisting in the organism.

Crude fractionation procedures,racteristics. This process is called fractionation and can be carried out in various ways, each of which groups compounds according to one or more particular features. Thus solubility, size, shape, electrical charge and several other features may influence the grouping.

Chromatographic fractionation procedures,Chromatographic procedures are the most diverse and the most widely used techniques in the fractionation of extracts. There is no doubt that they have made possible the isolation of many naturally occurring compounds.作者: exophthalmos 時間: 2025-3-26 04:50
Layer chromatography,Layer chromatography is useful in fractionation, not only as a final process for purification of comparatively small amounts of almost pure compounds, but also as a method for designing some types of column separation and also for monitoring the composition of fractions obtained by other fractionation processes.作者: 冰雹 時間: 2025-3-26 11:07
General methods,The methods used in the extraction, fractionation and isolation of compounds from natural sources have been described in Chapters 3–7.
