Abstract Products obtained after plant cell injury were studied by dividing white cabbage leaves (Brassica oleracea) in two parts. One part was heated to denaturate enzymes, homogenized, and stirred for six hours. After chromatographic separation and appropriate derivatization, the fractions were analyzed for low molecular weight compounds by GCMS. The other part was homogenized without cooking, but treated and analyzed in exactly the same way as the non-cooked sample. Comparison of the thus obtained products revealed that — besided already well known lipid peroxidation processes,e.g. generation of stress hormones as well as liberation and oxidation of phenolic compounds — a main but less known way of oxidative destruction was observed: epoxidation. The reaction not only involves unsaturated fatty acids, but also sterols and terpenes. This seems to be a typical response of plant cells to injury.Zur Untersuchung der Prozesse, die nach Zellverletzung ablaufen, wurde ein Weißkohlkopf geteilt. Die eine Hälfte wurde gekocht, um Enzyme zu zerstören, und dann homogenisiert. Das Homogenisat wurde bei Raumtemperatur sechs Stunden an der Luft gerührt. Nach chromatographischer Trennung wurden die einzelnen Fraktionen nach entsprechender Derivatisierung mittels GC-MS auf niedermolekulare Inhaltsstoffe untersucht. Die andere Hälfte des Weißkrautes wurde ungekocht in gleicher Weise homogenisiert, aufgearbeitet und analysiert. Der Vergleich der so erhaltenen Produkte ergab, daß neben bereits bekannten Lipidperoxidationsprozessen wie z.B. der Bildung von Streßhormonen und der Freisetzung sowie Oxidation von Phenolen ein weniger bekannter Weg oxidativer Umwandlung beobachtet wurde: Epoxidierung. Sie betrifft nicht nur ungesättigte Fettsäuren, sondern auch Sterole und Terpene. Diese Reaktion scheint eine typische Antwort von Pflanzen auf Zellverletzung zu sein.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
