Abstract:	This research about determinate the concentration of Ascorbic acid in guava leaves and baobab(new&old)by two methods ,the first method is titration the samples against iodine solution(0.005M) using starch as indicator and the results was (0.736mg/100g) in guava leaves, (4.76mg/100g) in baobab "new" and (2.95mg/100g) in baobab "old". The second method by High Performance Liquid Chromatography and the result was (3.23mg/100g) in guava leaves,(17.04mg/100g) in baobab "new" and(12.28mg/100g) in baobab "old". Then we compare this results with the standard concentration of Ascorbic acid in guava leaves and baobab (373mg/100g).
