33) Hyperforin is an organic molecule with a molecular mass of 536.797 grams/mole, and is produced by a plant called St. John's wort. Hyperforin may been antidepressant properties in humans (though this is not known with certainty). Recently, chemists have reported the synthesis of hyperforin from inexpensive, small molecule precursors. How you could determine whether a sample of hyperforin was isolated from the St. John's wort plant, or produced by a synthetic chemist
