However, when given either intraperitoneally or orally as a purified product, a bell-shaped dose-response was observed, which limits its clinical use. In the present study, we have studied in mice the anti-inflammatory and anti-nociceptive activities of standardized plant extracts derived from the Cannabis sativa L. In stark contrast to purified CBD, the clone extract, when given either intraperitoneally or orally, provided a clear correlation between the anti-inflammatory and anti-nociceptive responses and the dose, with increasing responses upon increasing doses, which makes this plant medicine ideal for clinical uses.

It was thin, short white crystals and had a melting point range or degrees Celsius. This was a white powder and had a melting point range of degrees Celsius. Discussion To confirm that the final product of the synthesis was aspirin, an IR spectrum of the product was taken.

This spectrum showed a broad peak at Hydroxyl groups tend to show characteristic peaks between cm The Nujol contains many hydrocarbons which produce a very strong peak in the range. The structure of aspirin also indicates that there should be a peak for a carbonyl ester, and a carbonyl acid.

These peaks usually occur in the cm-1 and cm-1 range respectively. The spectrum showed a peak at cm-1 which indicated the ester carbonyl and a peak at cm-1 for the acid carbonyl. There are also smaller peaks which indicate the other carbon-oxygen groups of the aspirin.

However, these lie in the finger print region of the spectrum and are therefore too hard to differentiate. The melting points of both the salicylic acid and aspirin were taken as other means to identify, and test the purity of the products.

Both the melting points of salicylic acid and aspirin were consistent with the literature values which are degrees Celsius and degrees Celsius respectively. This shows that both the products were relatively pure.

The ferric chloride test was used to compare the salicylic acid, crude aspirin, and purified aspirin. After the addition of the ferric chloride, the salicylic acid solution turned purple, and both the aspirin solutions were yellow.

Because both the aspirin solutions were yellow, there was not any unreacted starting material present in the product. If any was present in the crude or purified product it was not in a high enough concentration to complex with the ferric chloride to create the purple color. The salicylic acid was obtained with One possibility for loss of product could be during the acidification step.

The synthesis of the salicylic acid is done by creating the anion of the acid which is soluble in the aqueous solution. It is then protonated to crash the salicylic acid out of solution.

If not enough acid was added to protonate all the product, some will stay in the aqueous solution and will be lost. Another source of product loss is during the recrystallization. Because it is impossible to fully precipitate compound out of a solution, a small amount will always be loss.

The aspirin was obtained with Aspirin’s prevention of cardiovascular disease (CVD) events in individuals with type 2 diabetes mellitus is controversial. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) and aspirin all affect the cyclooxygenase enzyme.

An stable external preparation containing Aspirin which is characterized in mixing Aspirin together with at least one substance selected from an ester of an organic acid having 2 to 20 carbon atoms, a glycerol fatty acid ester, silicon oil, hydrocarbon oil and crotamiton.

Mar 23,  · What is the purpose of adding concentrated sulfuric acid in the preparation of methyl salicylate? Sulfuric acid is used in esterfication reactions as a catalyst.
