Ms Hanan,

The similar question we have answered for you earlier.

some of the extracts we have referenced.

let us know what you like to derive from it. then it will be easy to conclude and give the right answer to your question by the experts.

all the best

"Oxalate" (oxalic acid) could be one of natural plant extracts in star fruit which could strongly bind to free calcium. However, it is also able to bind magnesium ions.

Oxclic acid may be obtain in large quantities (you may want only plant extract not purified oxalic) from rhubarb plants Rheum spp.
