Recognition and Achievements

  • Highly cited researcher (in Agricultural Sciences) by Thomson Reuters, 2014, 2015.

 

Research Interests

  • Transition metal complex-based fluorescent probes for ultrasensitive detection of small molecules of biological importance, such as H2S, NO, NO2, and 1O2.
  • High throughput assay-guided isolation and characterizations of natural products with alpha-amylase inhibitory activity and anti-aging activity (using yeast as a model), induced phytoalexins from plant seeds.
  • Chemistry of dietary organosulfur compounds with regard to their activity as a natural H2S donors in biology.

 

Research Highlight

Ref: Liang, D., Wang, C., Tocmo, R., Wu, H., Deng, L. W., Huang, D.J. Hydrogen sulphide (H2S) releasing capacity of essential oils isolated from organosulphur rich fruits and vegetables. J. Funct. Foods 2015, 14, 634-640. 

Hydrogen sulfide (H2S) is a gaseous signaling molecule with multiple biological functions in human body. A fluorescent probe based method for H2S releasing capacity assay in cell lines was developed, and the H2S releasing capacities of 10 organosulfur rich foods (garlic, red onion, yellow onion, scallion, shallot, leek, spring onion, Chinese chives, durian, and stinky beans) were evaluated and ranked. Stinky beans (a vegetable from South East Asia) topped the ranking with incredible H2S releasing capacity, followed by garlic and yellow onion.
