D-(-)-Salicin Uses

D-(-)-Salicin has the effects of treating colds, fever and infection, and relieving arthritis pain and low back pain.
D-(-)-Salicin, a non-phenolic glucoside compound extracted from meadows, is mainly used as a substitute for quinine.
D-(-)-Salicin is used for antipyretic, analgesic and anti-rheumatic.
D-(-)-Salicin is a substrate for the determination of β-glucosidase. nitric acid reagent.

Effect of D-(-)-Salicin on Xylan

Amongst different carbon resources, xylan was discovered to be the only inducer of endoxylanase production by Penicillium janthinellum MTCC 10889 in immersed societies. Endoxylanase synthesis in xylan-induced cultures was initially hindered following synchronised xylose enhancement, potentially through an inducer exclusion mechanism, but it recovered and also reached optimum levels at a later growth stage (120 h). Added xylose after 30 hours of development might not apply its full repressive effect. Although sugar was shown to be an extra potent repressor than xylose, supplements with D-(-)-Salicin (an alcoholic β-glucoside consisting of d-glucose) as well as pure xylan caused a rise in enzyme synthesis by ca. 3.22-fold, followed by a continual high-yield enzyme at least up until the 144th hour of growth. Salicin was considerably less inducible in xylan-inducing cultures when included after 30 hours of development. Adding D-(-)-Salicin as well as xylan helped to partially get over the repressive effect of xylose and glucose. The failing of D-(-)-Salicin to restore endoxylanase synthesis in actinomycin D and also cycloheximide prevented xylan-induced societies, recommending that salicin was incapable to start afresh synthesis of the enzyme.

The Difference Between Extracting and Synthesizing D-(-)-Salicin

Deuterium NMR characterization of the all-natural abundance of 4 commercially readily available samples (Kahlbaum, Aldrich, Fluka, along with Extrasynthese) of D-(-)- Salicin in comparison with 2 drawn out examples from Salix Humboldt and also Salix sativa and one synthetic product, contrasted pentaacetic acid derivatives 2 as well as reported diacetyl salicyl alcohol4. Product 2 from S. humboldiana and also samples from salicin Kahlbaum revealed average (D/H) aromatic values of 117 and also 121 ppm, while for the remainder values of 146, 154, 153 and also 150 ppm were observed, Thus it was revealed that the salicin Kahlbaum was derived from the remove. The (D/H) worths at the 5′ as well as 6′ placements of the sugar moiety suggest theories regarding the origin of the glucose residues, distinguishing those from C3 or C4 plants. Analysis of 4, derived from 3, formed in the β-glucosidase hydrolysis of salicin 1, exposed a trend (D/H)4(para) > (DH) in indigenous samples from S. purpurea and Kahlbaum 3(meta) concerning (D/H)5( meta) > (D/H)6(ortho), the initial example of a deuterium pattern for an ortho-oxo-substituted phenylpropane. Three samples from commercial 1 (Aldrich, Fluka, as well as Extrasynthese) and also the synthetic sample showed practically the very same deuterium content (about 153 ppm) at positions 4 and also 6, while for both meta placements (D/H)3 > (D/ H)5 (about 162 as well as 140 ppm, specifically). Item 4 was the acid-catalyzed deuteration obtained from 3, revealing differential deuterium incorporation at the two meta-positions (ortho/para to the activated phenolic hydroxyl group).

Production Method of D-(-)-Salicin

It is prepared by extracting the bark and leaves of willow plants with hot water. Poplar and willow trees are rich in herbivore-fighting compounds called salicin, the original source of the widely used painkiller aspirin.
