Stroma lamellae and grana stacks prepared by French press rupture of spinach (Spinacia oleracea) chloroplasts contain similar amounts of beta-carotene on a protein basis. The grana fraction has considerably more xanthophylls than does the stroma fraction. Total carotenoid to chlorophyll ratios are similar for both fractions.
