A queous Neem Exatract as corrosion inhibitor for mild steel in acidic media.
salam alaikum
it is possible using it depend on the solution pH, conc, Temp, and other factors.
Its extraction depend on conditions and hydrodynamics. If you have specific conditions i may answer in details.
Dear Prof. F. K. Matlub,
The conditions are as follows:
1- 1.0 M HCl aqueous solution
2- Temp. 303 K and also higher temperatures: 313, 323, 333, and 343 K
3- Time for 6 Hours.
4- The aqueous extract of 1 g dry Neem leaves (soaked in 70 ml at room temperature for one hour) and diluted to I.0 L that has 1.0 M HCl).
Dear Ibrahim
The main disadvantage of using plant materials as corrosion inhibitors is their instability; they are readily biodegradable as well as their purification and economic efficiency. In some cases, thermal stability is crucial

Many thanks for your answer Prof. F. K. Matlub.
Have a nice weekend.
Many thanks for your answer Prof. Bahram Hosseini.

Aqueous extract of a certain plant as corrosion inhibitors. However, moment water comes in contact with the material corrosion start. Instead if you try insoluble oils may help in prevention of corrosion of mild steel.
