Bitter orange SRMs: Tools for product analysis/quality
Date:5/16/2008

The National Institute of Standards and Technology (NIST) has developed Standard Reference Materials (SRMs) for bitter orange, long used in folk medicine and now increasingly used in herbal weight-loss products. Researchers can use the new materials to develop and test analytical methods for compounds in bitter orange, or as control materials for quality assurance of their measurements. The NIST samples do not offer scientific evidence to address the use of bitter orange for health purposes.

Also known as Seville orange, sour orange, and Zhi shi, bitter orange has been used in traditional Chinese medicine and by indigenous people of the Amazon rain forest for nausea, indigestion and constipation. Current uses of bitter orange are for heartburn, loss of appetite, nasal congestion and weight loss. Users also apply it to skin for fungal infections such as ringworm and athletes foot.

Bitter orange has been used as a substitute for ephedra, a dietary supplement for weight loss now banned by the U.S. Food and Drug Administration (FDA). The dried fruit and peel of bitter orange (and sometimes the flowers and leaves) are taken by mouth in extracts, tablets and capsules. Bitter orange oil also can be applied to the skin. NIST supplies standardized samples of bitter orange in three forms that represent different analytical measurement challenges: ground fruit, extract and solid oral dosage form (tablets).

The National Institute of Healths (NIH) National Center for Complementary and Alternative Medicine (NCCAM) affirms that there is not enough scientific evidence to support the use of bitter orange for health purposes. It notes many herbal weight-loss products now use bitter orange peel in place of ephedra. However, bitter orange contains the chemical synephrine, which is similar to the main chemical in ephedra. The U.S. FDA banned ephedra because it raises blood pressure and is linked to heart attacks and strokes: it is unclear whether bitter
