 Title    The Determ ination o f Prolam ellar Bodies and Saponins in E tioplasts and Leaves o f A vena sativa L  
 Abstract    Prolamellar body tubules in etioplasts are composed mainly of two saponins. The determination o f these sapo-nins in leaves, etioplasts or subfractions of etioplasts is re­ commended to evaluate the concentration of these tubules in a given fraction. Using a densitometer after TLC-separa-tion of the saponins measurements are carried out in a short time with high accurancy. Also the absolute concen­ tration of these saponins can be determined. Problems in the quantification o f the saponins in leaf samples can be overcame with filters of different wavelengths.

 Title    Stimulation of Pancreatic Lipase Activity by Saponins Isolated from Medicago sativa L  
 Abstract    Saponins isolated from Medicago sativa L. appeared to stimulate lipolytic activity and did not influence amylolytic or proteolytic activity of Neopancreatinum (extract of pancreatic enzymes: lipase, proteases and amylases). Saponins isolated from the aerial part of Medicago sativa L. were demonstrated to stimulate lipase activity more effectively than saponins sepa­ rated from the root of this plant. When saponins were treated with 0.02 m HC1 at 37 °C for 1 hour their lipase stimulation ability did not change. The saponins stimulated Neopancreatinum lipolytic activity more in­ tensively in the presence of sodium cholate.

 Title    Protochlorophyllide Photoconversion Initiates the Transformation of Reaggregated Prolamellar Body Tubules in vitro  
 Abstract    Completely dissolved components o f native prolam ellar body/prim ary thylakoids PLB/PT were induced to reaggregate into tubular structures in vitro. Incubation o f these pchlide con­ taining PLB-like tubules under red light with N A D PH : pchlide oxidoreductase led to a specific association of the enzyme protein to the tubules. Photoconversion of the pigment initiates the dispersal of reaggregated PLB-tubules as indicated by changes in the content of their main constituent saponin.

 Title    Field Desorption and Fast Atom Bombardment Mass Spectrometry of Spirostanol and Furostanol Saponins from Paris polyphylla  
 Abstract    The application o f field desorption and fast atom bom bardm ent mass spectrometry for molecular weight determination and structural elucidation o f spirostanol and furostanol saponins isolated from Paris Polyphylla Sm. (Liliaceae) is reported. The capacity and lim itations o f these methods for sugar sequencing, differentiation o f isom ers and purity control o f oligoglycosidic natural products are discussed.
