	Title	Die quantitative Bestimmung von Chloroplastenpigmenten im picomol-Bereich mit Hilfe einer isochratischen H PLC-M ethode A Method for the Quantitative Estimation of Chloroplast Pigments in the Picomole-Range by Use of a Isocratic HPLC-System
	Abstract	A method is described for the estimation of the pigment content in chloroplasts by means of H P L C . The method is highly sensitive. Less than one picomole of individual pigments — equivalent to 1 m illigram m e fresh weight of spinach leaves — is needed for quantitative analysis. Analysis time is only 15 min, whereas in routine determination by thin layer chromatography a single sample needs 4 hours to be completed. Moreover the pigments are protected against desintegration by light and air. U sin g a isocratic H P LC -m eth od no equilibration of coloumns is necessary, thus permitting four runs per hour.

	Title	Photodynamic Damage to Isolated Chloroplasts: A Possible Model for in vivo Effects of Photosynthetic Inhibitor Herbicides
	Abstract	The breakdown o f chlorophylls, carotenoids, and linolenic acid together with the form ation o f malondialdehyde and ethane was followed in isolated pea chloroplast membranes. Breakdown was enhanced by light, oxygen, D 20 and rose bengal, but retarded by crocetin. The results are discussed in relationship to the role o f singlet oxygen in prom oting dam age in vivo.
