Function and .

Content determination:

Take this product is about 20mg, accurately weighed, set 50ml volumetric flask, dissolved in methanol and diluted to volume, shake, precise amount of 1ml, home 25ml volumetric flask, add methanol to the mark, shake. According to the spectrophotometric method , was measured at 275nm wavelength absorbance, according to Bergenin (C14H16O9) of the absorption coefficient (E1% 1cm) 248, that is too. The dried product by product basis, with Bergenin (C14H16O9) should be 97.0% ~ 103.0%.

 Plant source:

A.hortorum. & Ltbr> [alias] Bergenin lactone, low tea factor, low tea-I, saxifrage prime, rock cabbage rather, bergamot with quality, ghost lights gather factors, Bergenit, Vakerin, Arolisic acid B, Ardisic acid B, Corylopsin, Cuscutin, Peltaphorin

Pharmacological effects:

This product has analgesic, sedative, hypnotic effects and stability. The analgesic effect was weaker than pethidine, a strong anti-inflammatory drugs in general. No dose in the treatment of respiratory depression, do not cause gastrointestinal smooth muscle spasm. Of chronic persistent pain and visceral better dull, sharp acute pain (such as post-operative pain, trauma pain, etc.), advanced cancer pain less effective. Analgesic effect in the same time, can cause sedation and hypnosis. This product is yet to clarify the mechanism of action may be related to inhibition of brain stem through the ascending reticular activating system, block dopamine receptors in brain function. The amount of non-addictive treatment.

1 cough

2 of the trachea and lung tissue respiration: the role of thiol-containing groups Jiwei necessary enzyme systems, can reduce the tissue respiration, but the effect is not strong.

3 anti-inflammatory; clinically for the treatment of chronic bronchitis and chronic gastritis. Of gastric and duodenal ulcers, are also effective
