- Degradation kinetics and mechanism of lithospermic acid under low oxygen condition using quantitative 1H NMR with HPLC-MS
-
A novel quantitative 1H NMR (Q-NMR) combined with HPLC-MS method has been pro posed for investigating the degradation process of traditional Chinese medicine (TCM) components. Through this method, in-situ monitoring of dynamics degradation proc

- Isolation and identification of degradation products of salvianolic acid A by NMR and LC-MS
-
Salvianolic acid A was subjected to thermal degradation condition in distilled water at 90 °C. Four degradation products, including two novel compounds (1, 2) and two known ones (5, 6), were isolated by reverse-phase semi-preparative liquid chromatography and identified on the basis of NMR and MS data. Other two degradation products (3, 4) were determined by LC-MS analysis. 2010 Published by Elsevier B.V.
