“… 56 Another molecular ion at m / z [M + H] + was identified as flavogallonic acid, and was consistent with the literature found in the negative ESI-mode of T. chebula . 57 The results of HPLC-MS analysis of T. chebula (fruits) showed a protonated ion with m / z 323.0762 [M + H] + and sodiated ion as adduct at m / z 345.0580 [M + Na] + . Based on the literature, this compound was putatively identified as leucodelphidin.…”

“…The free proline in normal people is 235 μM, [19] while it can reach the range of millimoles in some plants. [20] Therefore, the detection range of current proline sensors does not apply to plants. Moreover, the current proline sensors were always developed on the traditional glass carbon (GC) electrode or gold electrode, the volume of these electrodes was too large for in vivo detection of plants.…”

Proline is an important amino acid, which is crucial to plant growth and development. Accurate analysis of proline content is of great significance for understanding its physiological mechanism in plants. In this paper, according to the requirements for in‐situ detection in plants in precision agriculture, an electrochemical molecular imprinted polymers (MIP) sensor for determining proline in living plants was developed. Polypyrrole (PPy) was used as the functional monomer. To improve the performance of the MIP sensor, Au nanoparticles (NPs) were electrodeposited on the screen‐printed electrodes (SPEs) electrode. Thionine (Thi) was then electropolymerized on the SPEs to be used as an internal reference signal molecule. The MIP‐based proline sensor has the widest detection range of 1×10−16 −0.01 M. And its detection limit is the lowest (9.18 aM) so far. It was also used for measuring free proline in the leaves of living cucumber seedlings under salt stress. The MIP‐based proline sensor has an important prospect for detecting the physiological status of plants in situ and will play an important role in smart agriculture.

“…Of these, 19 species grow in China, many of which have long been used as folk medicine (She, Zhang, & Yang, 2013; Wang, Zhang, & Yang, 2006). In the southwest region of China, because of its detoxification and hemostatic efficacy, Balanophora involucrata J. D. Hooker has been used for treating gonorrhea, syphilis, wounds and bleeding of the alimentary tract by the indigenous community (Tao, Zhao, Zhao, Cui, & Fang, 2012; Wang et al, 2013), and has been recorded in the Quality Standard of Chinese Crude Drugs in Hubei Province (Ge & Wan, 2008). Its related species ( Balanophora japonica Makino) could supposedly treat alcohol accumulation and has been recorded in The Compendium of Materia Medica ( Ben Cao Gang Mu ) (Li, 2006).…”

Balanophora involucrata J. D. Hooker has been known to possess potential anti‐inflammatory and antibacterial activities; however, its antiviral activity has not been evaluated so far. In order to find new neuraminidase inhibitors (NAIs), the neuraminidase (NA) inhibition activity of different B. involucrata extracts was evaluated. In this study, an in vitro NA inhibition assay was performed to identify which extract of B. involucrata exhibits (maximal) inhibitory activity against NA. Ultra high performance liquid chromatography/quadrupole time‐of‐flight–tandem mass spectroscopy (MS/MS) and molecular docking techniques were used to identify the specific compounds responsible for the anti‐influenza activity of the extract, and to explore the potential natural NAIs. The ethyl acetate extract of B. involucrata exhibited significant inhibitory activity against NA with 50% inhibitory concentration (IC50) value of 159.5 μg/mL. Twenty compounds were identified according to the MS/MS spectra; among them two compounds (quercitrin and phloridzin) showed obvious inhibitory activity against NA, with IC50 of 311.76 and 347.32 μmol/L, respectively. This study suggested that B. involucrata can be a potential natural source of NAIs and may be useful in the fight against ferocious influenza viruses.
