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).
