Question

what is reserved percolation?​

Answer 1

Hey mate!!

Percolation is the process of a liquid slowly passing through a filter. ... Percolation comes from the Latin word percolare, which means "to strain through." Percolation happens when liquid is strained through a filter, like when someone makes coffee. Drinking coffee can make you feel perky!

Hope this helps you...

Answer 2

Answer:In this process ,a part of the percolate ,generally 3/4th the volume of the finished preparation ,is reserved .Then the percolation process is continued till the drug is completely exhausted .The percolate is subjected to evaporation or distillation to convert it into a soft extract.This soft extract is dissolved in the reserve portion of percolate and then sufficient menstruum is added to produce the required volume.

The portion of the percolate which is reserved must be the first percolate because it is more concentrated.The portion of the percolate which is evaporated contained traces of active constituents of the drug.Hence,the major portion of the active constituents of the drug are saved from deterioration.
