Although strong intersubject variation in metabolite profiles was observed, clear differentiation between the samples obtained before and after chamomile ingestion was achieved on the basis of increased urinary excretion of hippurate and glycine with depleted creatinine concentration.
Antioxidant potential of intermediates in phenylpropanoid metabolism in higher plants
Prediction of anti-plasmodial activity of Artemisia annua extracts: application of 1H NMR spectroscopy and chemometrics.
Comparative mechanisms and rates of free radical scavenging by carotenoid antioxidants
Metabolomic strategy for the classification and quality control of phytomedicine: a case study of chamomile flower (Matricaria recutita L.).
It was found that the origin, purity and preparation methods contributed to the differences observed in prepared chamomile extracts and NMR-based metabolomics enabled the elucidation of the molecular information embedded in the spectra responsible for the observed variability.
In vitro keratinocyte antiproliferant effect of Centella asiatica extract and triterpenoid saponins.
Results suggest that the potential use of C. asiatica extracts as a topical anti-psoriatic agent is worthy of further investigation.
