The focus of this thesis was to study the chemotaxonomic relationship of selected southern Australian marine brown algae of the genera Cystophora and Sargassum. Consequently, this resulted in the isolation and structure elucidation of six new terpenoids from two southern Australian marine brown algae Cystophora moniliformis and Sargassum fallax together with 10 previously reported natural products. As a result of the re-isolation of these known secondary metabolites, updated and complete structural characterisation data could be provided for the first time for 7 of these compounds.

Optimazize the in vitro Ngoc Linh ginseng lateral root culture and multiplicate the root biomass is more stable and higher in bioreactor system. Determine and evalute the effect of different types, and concentrations of five elicitors (SA, JA, ABA, CHN và YE) on producing saponin compounds. Next, combine in various types of elicitors to enhance effectiveness of the saponin accumulation, and determine the best elicitation time to develop the highest saponin in LRs of Ngoc Linh từ ARs in vitro.

As one of the most important families of non-natural poly-mers with the propensity to form well-defined secondary structures, theb-peptides are attracting increasing attention. The compounds incorporatingb-amino acid residues have found various applications in medicinal chemistry and biochemistry.The conformational pool ofb-peptides com-prises several periodic folded conformations, which can be classified as helices, and nonpolar and polar strands.The latter two are prone to form pleated sheets.

Cholangitis refers to an acute infection of the biliary tree, and has the potential to cause significant morbidity and mortality. It occurs secondary to stasis or obstruction of bile compounded by the presence of bacteria. Choledocholithiasis (stones in the common bile duct) has long been the most common cause of obstruction, however, strictures, tumors, or manipulation of the common bile duct may cause bile stasis, leading to the predisposition to bacterial infection of the biliary tree.
