Novel Patent Pending Turmeric Extract Offers Innovative Curcuminoid Profile

Last updated on

The spice turmeric (Curcuma longa​) known for its vibrant orange pigment, is a member of the Zingiberaceae family along with ginger, cardamom, and galangal.  Turmeric use dates back thousands of years in India as a pillar of the country’s cuisine as well as its system of traditional medicine known as Ayurveda.[1]  Traditional uses of turmeric include supporting digestive, liver and joint health as well as providing a balanced inflammatory response.  Turmeric also has various applications in Traditional Chinese medicine (TCM).[2]

More recently, researchers have discovered the presence of the bioactive polyphenols known as curcuminoids in turmeric (curcumin, demethoxycurcumin and bisdemethoxycurcumin), which all have antioxidant properties, and are thought to contribute to its traditional health uses.[3].  With all the potential health benefits turmeric has to offer, poor bioavailability of the curcuminoids present in the root can limit its application.[4]  Turmeric extracts allow for more control, lower material input requirements and standardized dosing of the desired active components. 

Typical commercial grade turmeric extracts are comprised of 77% curcumin, 17% demethoxycurcumin and 3% bisdemethoxycurcumin (BDMC).[5]  Curcumin is naturally present in the greatest amount, and the market is abundant with high curcumin turmeric extracts.  However, BDMC is gaining traction as a novel antioxidant in turmeric.  While some standardized extracts on the market have begun to focus on BDMC as the principal constituent, they typically achieve a maximum of only 30% BDMC.  Meanwhile, Vidya Herbs has created a new, DNA verified extract which contains a minimum of 70% BDMC.  This concentration represents an approximately 23-fold increase in BDMC compared to conventional grade turmeric extracts and a reversed curcuminoid profile. 

Vidya Herbs has begun a line of research investigating several health benefit categories including balanced inflammatory response and cognitive health.

Preclinical studies showed Vidya Herbs’ BDMC rich extract had a significantly higher capability to support a balanced inflammatory response compared to a conventional turmeric extract as demonstrated by nitric oxide scavenging activity and inhibition of xanthine oxidase and lipoxygenase.[6]

Acetylcholinesterase is an enzyme which catalyzes the breakdown of acetylcholine and other choline esters that function as neurotransmitters.[7]  Vidya Herbs conducted a preclinical study which demonstrated that the BDMC extract had a higher inhibitory effect against acetylcholinesterase activity than regular turmeric extract, which indicates potential neurological benefits to improve cognitive function.  The BDMC extract showed a 4.8- and 5.39-fold higher inhibitory potential of acetylcholinesterase and butyrylcholinesterase with IC50 values of 29.08 and 33.59 µg/mL, respectively, compared to the regular turmeric extract.  These results indicate that the BDMC extract could improve the cholinergic functions via dual inhibition of cholinesterase. 

These benefits may be in part due to increased bioavailability of the BDMC in comparison to curcumin.  A preclinical study simulating digestion found that the bioavailability of the BDMC in Vidya Herbs BDMC extract was 4.4-fold higher than the curcumin in a conventional turmeric extract.  This study also showed that concentrations of BDMC in plasma serum were significantly higher than curcumin levels and remained elevated for 24 hours demonstrating that a once daily dose may be sufficient.

Although further research is needed, this 70% BDMC extract may offer substantial benefits over typical curcuminoid extracts while simultaneously requiring a lower dose to provide new options for various formulations and functional foods.

Those interested evaluating the company’s BDMC extract for product development purposes can request samples from Vidya Herbs’ Red Bank, New Jersey office via e-mail (vasb@ivqlnureofhfn.pbz​) or phone at (732) 784-1587.
