Beavers are fond of willow bark, which contains a chemical called salicin
In combination with white willow's anti-inflammatory flavonoids, salicin
is thought to be responsible for the plant's pain-relieving and anti-inflammatory effects.
Herbal medicine has made many contributions to commercial drug preparations manufactured today including ephedrine from Ephedra sinica, digitoxin from Digitalis purpurea, salicin
(the source of aspirin) from Salix alba and reserpine from Rauwolfia serpentina.
It is hypothesised that the phenolic glucoside salicin
in poplar is a major taste stimulant for C.
5 ul/litre) blood agar and fermentation of sugars (L-arabinose, glucose, lactose, maltose, mannose, raffinose, salicin
, D-sorbitol, starch, mannitol, rhamnose and sucrose) were performed according to standards procedures (Holt, 1986).
Before we got pain relief from aspirin, for example, its key ingredient salicin
could be extracted by boiling willow bark.
Willow is rich in salicin
, the basis of modern aspirin, which was first sold in 1899.
Semi-industrial isolation of salicin
and amygdalin from plant extracts using slow rotary counter-current chromatography.
In fact, the original aspirin came from the inner back of willows, which contains 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.
