Bioactive compounds in green spices
ARNOŠTOVÁ, Lucie
The bachelor thesis focuses on the determination of the total content of phenolic compounds, individual majority phenolic compounds and vitamin C, contained in sweet basil (Ocimum basilicum), coriander (Coriandrum sativum), dill (Anethum graveolens) and lovage (Levisticum officinale). Firstly, the total content of phenolic compounds was determined by spectrophotometric analysis using Folin Ciocalteau agent in extracts from fresh and dried herb samples. Afterwards, particular representatives of phenolic compounds in the lyophilized material were identified by high-performance liquid chromatography (HPLC). Then the content of vitamin C in fresh samples from all selected plants was measured using high-performance liquid chromatography (HPLC). The highest concentration of phenolic compounds was discovered in lovage. The highest content of particular phenolic substances, quercetin and kaempferol, was also proved in lovage.
The archeobotanical research of the Early Modern waterlogged cesspit in Prague-Celetná street and possibilities of photography documentation
IRMIŠOVÁ, Jitka
Based on the macroremains analysis from Early Modern waste filling of the well in Prague Celetná street, dietary habits of Prague dwellers and the character of the city environment from the second quarter of the 18th century to the early 20th century were constructed. In total 44 015 macroremains were found, of which only 2 707 diasporas were wild-growing species. Strong predominance of crop confirmed hypothesis of well-into-cesspit transformation at the end of the 18th century. The species such as Nicotiana rustica, Piper nigrum and Ocimum basilicum, not commonly occurring in the archeological objects were recorded. The changes of the diaspora external structure influenced by their long-term deposition under anaerobic conditions were examined by electron microscopy method. A difference in subtle damage to the distinct diaspora structure along with the rate of diaspora organic pollution was noted.
