Jian-Chao Chen




2001-2006: Ph. D., Natural Products Chemistry, Kunming Institute of Botany, Chinese Academy of  Sciences, China. Advisor: Prof. Ming-Hua Qiu
1990-1995: B.Sc., Chemistry,  Sichuan University, Chengdu, China.

Current position

December 2012- current: Postdoctoral researcher at University of Minnesota with Professor Peter W. Carr.

Research experience

Current research focuses on:

  1. Detecting samples, including plant materials, by using synthesized silica on 2D HPLC.  

Previous research experience:  

Many plants in China are used as traditional Chinese medicine by local people. For example, some of Hemsleya spp. tubers have been used as antibacterial remedy to treat sore throat, toothache, dysentery, bronchitis, and chronic cervicitis, while the fruits, vines, leaves and roots of Momordica charantia L. have been used in China for treating toothache, diarrhea, furuncle and diabetes mellitus. From the medicinal plants, especially genus Hemsleya and M. charantia, more than 200 natural compounds, including at least 80 new ones, were obtained. Some of the new compounds bear novel structures, such as tri-, penta-, and octa-cucurbitane structures. Some isolates showed obvious anti-cancer, anti-HIV, or hypoglycemic bioactivities.
