Im try the hydrolysis following method below .
The question is that we use acid afterwards for neutralization of product the salt formation takes place it also settles down along with product, we precipitate by adding ethanol But the salt will also be precipitated will remian in final product! How to cope the situation any method for only precipitating hydrolyzed gum ?
"Basic hydrolysis of purified D. sissoo gum was performed byusing the method given by Beltran [23]. The 5 g of purified gum washydrolyzed with saturated solution of barium hydroxide (200 mL)for 8 h at 100◦C. The hydrolyzed sample was neutralized with 1 MH2SO4.The resultant product was precipitated with ethanol, fil-tered and at 50◦C oven-dried".

A first precipitation should occur after the neutralization with sulfuric acid solution. The insoluble barium sulfate which is formed should be filtered out.
Then a second precipitation with ethanol should be conducted in the solution obtained by filtration. In this way the salts should be eliminated.
Thank you very much Prof. Alessandro Venditti . i will follow as you stated.
You're welcome.
Please if you try this let us know about the results.
Yes sir Indeed i will be in contact with you thanks for your kind reply.
