Pharmacokinetics of a Natural Self-emulsifying Reversible Hybrid-Hydrogel (N'SERH) Formulation of Full-Spectrum Boswellia serrata Oleo-Gum Resin Extract: Randomised Double-Blinded Placebo-Controlled Crossover Study.
The oleo-gum-resin of Boswellia serrata, an Ayurvedic herb for the treatment of chronic inflammatory diseases, contains both volatile (terpenes) and nonvolatile (boswellic acids) molecules as responsible for its bioactivity. The present randomized, double-blinded, placebo-controlled, crossover study evaluated the human pharmacokinetics of a 'natural' hybrid-hydrogel formulation of a unique full-spectrum boswellia extract (BFQ-20) (standardized for both volatile and nonvolatile bioactives) in comparison with unformulated extract (U-BE), for the first time. Mass spectrometry coupled with LC (UPLC-MS/MS) and gas chromatography (GC-MS/MS) measurements of the plasma concentration of boswellic acids and α-thujene at different post-administration time points followed by a single dose (400 mg) of U-BE and BFQ-20, to healthy volunteers (n = 16), offered 4-fold enhancement in the overall bioavailability of boswellic acids from BFQ-20, [area under the curve (AUC) (BFQ-20) = 9484.17 ± 767.82 ng * h/mL vs. AUC (U-BE) = 2365.87 ± 346.89 ng * h/mL], with the absorption maximum (Tmax) at 6.3 h post-administration and elimination half-life (T1/2) of 15.5 h (p < 0.001). While plasma α-thujene was not detectable upon U-BE administration, BFQ-20 provided significant absorption, [AUC (BFQ-20): 298.60 ± 35.48 ng * h/mL; Cmax: 68.80 ± 18.60 ng/mL; Tmax: 4.12 ± 0.38 h; T1/2: 16.24 ± 1.12 h]. Further investigation of the anti-inflammatory effect revealed 70.5% inhibition of paw edema in rats compared to 38.0% for U-BE. In summary, the natural self-emulsifying reversible hybrid-hydrogel (N'SERH) formulation of boswellia extract using fenugreek mucilage (FenuMat®) significantly increased the solubility (58-fold), stability, and bioavailability of both the volatile and non-volatile bioactives which in turn improved the anti-inflammatory efficacy of Boswellia extract.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
