Drugs mentioned in formula, Separated Powders
1. Cleaned properly
2. Dried thoroughly
3. Pulverised (reduced to small size)
4. Sieved (80 mesh size).
5. Weighed
6. Mixed together uniformly.

7. STANDARDIZATION OF CHURAN
1. Churnas should be free flowing powders and
should not adhere or become moist.
2. Churnas are stable up to one year if they are
stored properly.
3. Finer the powder, better is its potency and therapeutic
value.

8. EVALUATION OF PHYSICAL PARAMETERS:
• 1) Determination of pH:-The pH of 1% solution of
formulated churna was determined using pH
meter (Elico pH meter).
• 2) Determination of Moisture content :-The
moisture content of churna was found using
halogen moisture determining apparatus (Mettler
Toledo).
• 3) Determination of Ash Values:- I. Total Ash Value
• 4) Alcohol Soluble Extractive Values:- Ethanol was
used as solvent in place of chloroform water and
remaining procedure was the same as that of
water-soluble extractive value.
pH meter
Moisture analyser

9. • 5. Determination of Heavy Metal Contamination
Test for Mercury:-
To 10 drops of test solution 6M Hcl was added to
get a white precipitate. The precipitate was then treated with 6M
ammonia solution. If the colour of precipitate changes to grey or
black colour then it indicates the presence of mercury.
