Abstract
In some flowers the aromatic compounds are stored as non-scented glycoside precursors in the vacuoles.
The removal of the sugar moiety from these compounds was facilitated by the activity of the
-glucosidases in floral tissue and is correlated with scent production.
Crude extracts from different stages of three scented flowers (Wrightia religiosa, Ervatamia coronaria and Gardenia jasminoides) were assayed for-glucosidase using p-nitrophenyl--D-glucoside (p-NGP) as the substrate.
Different kinds of flowers had different level of-glucosidase activity with the highest level found in Wrightia religiosa. The activity of this enzyme was detected in closed buds and was found to increase significantly in open flowers.
