Gang for their support and guidance for my research and for the enormous help and effect they have had on my life and scientific attitude. In addition, I thank them for their encouragement, patience, and confidence right from the beginning of my research. I would also like to thank Drs. Myron K. Jacobson, Victor J. Hruby, and Danzhou Yang for their teaching, advice, consultations, corrections, and generous help that have been critical to this work and my career planning. My thanks go out to Dr. Arpad Somogyi for his extremely helpful consultations and discussions about mass spectrometry and for providing an excellent resource for part of the work in this study. I also want to thank Dr. Neil Jacobsen for his teaching about the theory and application of NMR and assistance in its operation. My appreciation also goes out to Dr. Aniko Solyom and Veronica Rodriguez for their generous help in my use of their HPLC and LC-MS and discussion about the results obtained. Moreover, I want thank Dr. Guanjie Chen for his help with the anti- inflammatory bioassay, Dr. Yeisoo Yu for his help with DNA sequencing, Dr. Steven McLaughlin for plant material identification, as well as Jeffrey C. Oliver for consultation of phylogenetic analyses included in this study. I would also like to thank the past and present members of Dr. Gang’s laboratory. My thanks to Zhengzhi Xie and Hyun Jo Koo for their help with the DNA and secondary metabolites extraction, to Brenda L. Jackson for her assistance in instrumental operation, to Eric McDowell for revision of manuscript, and to Drs. Xiaoqiang Ma, Marycarmen Ramirez, Jeremy Kapteyn, Jennifer Wing and fellow students Shirley Chai and Amanda Scholz. Finally, I want to thank my parents Zonglu Jiang and Xiulian Li for their love, support, and encouragement throughout my growth. Moreover, I appreciate the help I received from my sister Hongmei Jiang in many aspects. Furthermore, I want to thank Yang Zhang for her love and care during this challenging time. Also, I want to thank all my friends for their general care, help, and confidence to me.
