The effects of differently processed leaves and the curd of fluted pumpkin (Telfariaoccidentalis)on beta carotene, iron, ascorbate, zinc, copper and calcium status of rats were evaluated. Fluted pumpkin leaf was divided into four (4) portions. One was shade-dried, another was sun-dried and the other was used to produce leaf curd. The last portion was not processed and served as the control. All the processed samples were milled to fine flour andeach of the pumpkin leaf flour was incorporated into rat chow for a 28-day study period. Twenty (20) male weanling rats were divided into four (4) groups of five (5) rats each. They were housed in individual metabolism cages and fed diets and water ad libitum. Blood samples were drawn before and after the experiment by ocular puncture and were used for biochemical analysis. Blood plasma was used to determine haemoglobin while serum was used to determine pro- vitamin A, ascorbate, ferritin, iron, copper, zinc and calcium. The liver was individually removed and analysed for liver ferritin, ascorbate and other micronutrients. The results showed that the rats fed rat chow supplemented with dried leaf curd had higher serum beta carotene, ascorbate, and ferritin than those of the other groups. The rats fed rat chow supplemented with shade dried-fluted pumpkin leaf had higher (p<0.05) haemoglobin level, liver beta-carotene and ascorbate than the other groups. The result showed that processing fluted pumpkin leaf into leaf curd improved serum beta-carotene, serum and liver ascorbate, serum ferritin and liver iron of rats more than other processing methods.
