The free amino acid content of aqueous extracts (preserved in 50 % glycerol) of pollen of Bangladeshi five
(5) common fruits flower of the Asteraceae family three, i.e. Mangifera indica L, Pistacho and Cashew;
Sapindaceae family one flower i.e. Litchi chinensis and Vitex glabrata family one flower i.e. Blackberry has
been investigated using a thin-layer chromatographic technique. The amino acid content was found to vary
from 0.75 to 2.25% of the total dry weight of pollen was estimated by a powerful oxidising agent (ninhydrin
reagent). Thirteen amino acids were identified, among them n-butyric acid, proline and aspartic acid were
present in almost all different pollen samples. The other major amino acids present in free from included
alanine, cystine, arginine, glutamic acid, isoleucine, glycine, leucine, methonine, tryptophan and tyrosine.
