| Study Title | 1H NMR spectroscopy-based metabolic profiling of Ophiocordyceps sinensis and Cordyceps militaris of water-boiled and 50% ethanol-soaked extracts |
| Study Type | NMR |
| Study Summary | Introduction Ophiocordyceps sinensis, a well-known Chinese complementary herb, is a rare and valuable therapeutic resource. Cordyceps militaris (C. militaris) is a commonly used substitute for O. sinensis. A metabolomic-based approach for exploring the similarities and differences in the metabolites of O. sinensis and C. militaris in water-boiled and 50% ethanol-soaked extracts is of great significance. Objectives To determine a vital role of extraction methodologies in influencing the metabolic composition of herbs, 1HNMR-based profiling was used to characterize the metabolic fingerprints of O. sinensis and C. militaris. Methods To make a distinction between the global metabolite profiling of O. sinensis and C. militaris extracts obtained from either the water-boiled or 50% ethanol-soaked methods, we screened the herbs samples using 1HNMR-based metabolic fingerprints combined with multivariate statistical analysis. Results This study revealed that a total of 43 (82.69% of 52) metabolites were detectable in both O. sinensis and C. militaris. According to the variable importance in projection (VIP) value and p-value from the Mann-Whitney test, 7 metabolites (alanine, aspartate, glutamate, mannitol, ornithine, serine, and trehalose) differed between O. sinensis and C. militaris. Arginine, glucose, putrescine, pyroglutamate, betaine, O-phosphocholine, and xylose differed significantly between the water-boiled and 50% ethanol-soaked methods used to prepare the herb extracts. Conclusion A total of 52 primary metabolites were identified and quantified from O. sinensis and C. militaris samples. The study suggests that a water-boiled extraction is much faster method and strongly recommended over the 50% ethanol-soaked method for both O. sinensis and C. militaris. |
