The difference between proportion extract and content extract

The two also differ in their detection methods, usage methods, and substance content.
1. Detection method: The detection of proportional extracts usually uses thin-layer chromatography (TLC) for qualitative detection, while the quality of content extracts needs to be evaluated through specific content determination methods.
2. Usage: Proportional extracts are commonly used in production, such as formula development in industries such as food, pharmaceuticals, and cosmetics, to develop specific properties of products. And content extracts are more suitable for specific scientific research, such as pharmacology, biology, or chemistry, to study the mechanism or effect of specific components.
3. Material content: Proportional extracts cannot detect specific content components, and their material content is extracted from raw materials based on fixed ratios. And the content extract focuses on the content of specific components, for example, some plant extracts may mainly contain flavonoids or polyphenols, and the determination of their content can evaluate the quality of the extract.
Taking rose extract as an example, the differences in proportion and content of the extract will be explained in detail.
Proportional extraction: If we extract roses in a 5:1 ratio, this means that using 5 kilograms of rose raw materials can extract 1 kilogram of extract. This extraction method mainly focuses on the yield ratio of the extract, without particularly paying attention to the content of specific components in the extract.
Content extraction: If we want to extract specific components from roses, such as flavonoids, and want to increase their content to 5%, then we need to use content extraction. This means that suitable solvents and methods need to be used to purify flavonoids in roses to 5%. This extraction method mainly focuses on the content of specific components in the extract.
So, the main difference between proportion extraction and content extraction is that the former focuses on the proportion of raw materials and products, while the latter focuses on the content of specific ingredients in the product.
