The ratio
of the extract is the extraction of concentrated raw materials such as
plant animals and extracts of the extract, flow extract or powder, the
number of raw materials before extraction and extraction of concentrated
products after the mathematical ratio.
The proportion of the extract is generally not very clear ingredients and content.
Such
as 10 kg of scutellaria extract extracted into 1 kg of powdered
products, we call the 10: 1 ratio of Scutellaria extract, the extract of
baicalin, baicalein and other important indicators there is no clear
standard.
