摘要
OBJECTIVE ″-omics″study represents an unbiased perspective to examine the bio-system to discover the novel biomarker(s)which might be overlooked when targeted analysis is performed instead.Urine,due to its ease of collection,minimal invasion involved and rich information of the downstream metabolites,has been extensively studied.Fermentum rubrum(Hongqu,HQ capsules)is a well-known traditional medicine with the claimed slimming effect which could be related to the reduction in the deposition of total cholesterol and glycerides.Lack in sufficient clinical evidence is always one of the leading reasons that hamper traditional medicines from gaining world-wide recognition.In our pursuit of scientific support for HQ capsules in managing obesity,we aim to examine the alteration of urinary metabolites in this small-scale human clinical research.METHODS 6 Chinese subjects were included and exposed to short-term administration of HQ capsules for 3d,twice daily,two capsules each dosing.The urine samples were collected for three days prior to the dosing and on the day following the last dosing.In total,96 urine samples were collected and then separated on hydrophilic interaction chromatography(HILIC)and analyzed by Agilent 6550 ESI-Quadrupoletime-of-flight(QTOF)mass spectrometer.RESULTS Under positive mode,two compounds were found to be present only in post-dosing urine,and one compound was significantly lowered in post-dosing samples.Those two compounds might be associated with the administered HQ capsules,which is formulated with multiherbal constituents.CONCLUSION Further elucidation on the structures of these compounds is needed to enable better understanding of the mechanism of HQ capsules in managing obesity.
