Preparation of aqueous C. sinensis extracts and acquisition of 1H NMR spectroscopy

C. sinensis (0.02 g) were mixed with 0.6 mL D2O (containing 0.05% w/w TSP) and followed by 2 × 20 s beating of 5,600 rpm and 20 s pause between the bead beatings using tissue homogenizer (precellys 24, Bertin technologies, Villeurbanne, France) and then ultrasonic-extracted for 1 hours at 25 °C. The resulting solutions were centrifuged at 12,000 g for 10 min at 4°C and aliquots of the supernatant (500 μL) were transferred into a 5-mm NMR tube. Solvent-suppressed 1D 1H ZGPR spectrum was then recorded. Water presaturation was achieved by irradiation of the water peak during the recycle delay (RD). A total of 64 free induction decays (FIDs) were collected into 32,768 data points at a flip angle of 90°, and a spectral width of 8012 Hz, giving an acquisition time (ACQ) of 5.99 s, with an additional relaxation delay (RD) of 10 s were used. The NMR experiment was carried out at 298K on a Bruker (Karlsruhe, Germany) Avance III 500 MHz spectrometer equipped with ultra low temperature probe.
