She carried out biochemical characterization and found that all isolates were positive for oxidase, catalase, indole production, nitrate reduction and fermentation of lactose, mannitol, sucrose and mannose while negative for citrate utilization and fermentation of maltose, arabinose, lactose, dulcitol, salicin
But its active ingredient is salicin
, which has an antiinflammatory effect and is derived from willow trees.
The active ingredient in aspirin, acetyl salicylic acid, is a synthetic derivative of the compound salicin
, which occurs naturally in plants, notably the willow tree.
Endoglucanase and [beta]-glucosidase activities were determined using carboxymethyl cellulose and salicin
(2-[hydroxymethyl]-phenyl-[beta]-D-glucopyranoside) as substrates, respectively.
Willow bark, an ancient remedy, which is used to treat fevers and arthritic complaints, has often been referred to as "nature's aspirin." Salicin
is its active ingredient.
It contains tannins and salicin
, a plant salicylate.
is chemically interrelated to aspirin and possesses almost comparable pharmacological activities.

The current work examines the related gene TAS2R16, which codes for a molecular receptor that binds salicin
