Protocol for extraction of salicylic acid - (Jul/04/2006 )

Hi,

Is there a protocol available for the extraction of salicylic acid from turmeric,peanuts, tomato or radish? There is one for extracting salicylic acid from willow bark but i've not been able to access the protocol or the bark.

please help me with this.

Why do you need the bark? Aspirin (or dispirin) is salycilic acid essentially, you could just use that if you need salycilic acid.
