Abstract

The leaves of Spinacea olarecea L. (spinach), Brassica olarecea V. (cabbage), Hibiscus sabdriffa L. and Lactuca sativa L. (lettuce) were analyzed for iodine, moisture, dry matter and ash contents. The results have shown that Hibiscus sabdriffa has the highest iodine (0.0043%) and dry matter (74.60%) contents; salad has the highest moisture content (10.41%) and cabbage with the highest ash content (6.35%).
