Description
| - Souhrn: Těkavé látky (terpeny) jsou převážnou součástí silic1. Jsou obsaženy v různých částech rostlin: v květech, plodech, listech, kůře i kořenech. Nacházejí se v žláznatých chlupech, papilách, žláznatých buňkách, nádržkách, kanálcích a mezibuněčných prostorách. Tyto látky ((+)-a-pinen, (-)-camphen, (-)-b-pinen, (+)-3-caren, R-(-)-a-phellandren, R(+)-limonen aj.) byly stanovovány v různém rostlinném materiálu např. jehličí a listí stromů (čeledi Pinaceae, Juglandaceae) a léčivých aromatických a kořeninových rostlinách (čeledi Apiaceae, Lamiaceae). Pro extrakci stanovovaných látek ze vzorků jehličí a listí (Picea abies, P. omorika, P. pungens, Juglans regia, J. nigra, J. sieboldiana), plodů a listů (Carum carvi L., Coriandrum sativum L., Pimpinella anisum L., Foeniculum vulgare Mill., Salvia verticillata L., Salvia pratensis L., Ocimum basilicum L.) bylo použito několik způsobů extrakce: extrakce ultrazvukem, extrakce třepáním do rozpouštědla, destilace s vodní parou, extrakce dle Soxhleta, super (cs)
- Summary: Volatile compounds (terpenes) are the main component of essential oils1 and are contained in various parts of plants: in flowers, fruits, leaves, bark and roots. They're located in glandular trichomes, papillae, glandular cells, receptacles, ducts and intercellular spaces. These compounds ((+)-a-pinene, (-)-camphene, (-)-b-pinene, (+)-3-carene, R-(-)-a-phellandrene, R(+)-limonene etc.) were determined in plant material -- in tree needles and leaves (Pinaceae and Juglandaceae family), in medicinal aromatic plants and in spice (Apiaceae and Lamiaceae family). Several methods were used for the extraction of determined compounds from needles and leaves (Picea abies, P. omorika, P. pungens, Juglans regia, J. nigra, J. sieboldiana), or seeds and leaves (Carum carvi L., Coriandrum sativum L., Pimpinella anisum L., Foeniculum vulgare Mill., Salvia verticillata L., Salvia pratensis L., Ocimum basilicum L.): sonication, liquid extraction in shaker, steam distillation, Soxhlet extraction, supercritic
