Daflon Synthesis Lab Report

Decent Essays
Moldovan et al. propounded a different method of extraction from pharmaceutical tablets by extraction of with 0.5 M NaOH. Samples were then filtered and transferred to calibrated flasks with double quantity of distilled water [25].
Author selected five Daflon tablets (a mixture of micronized flavonoid glycosides consisting of 450 mg of diosmin and flavonoid extract equivalent to 50 mg of hesperidin) were powdered, and sonicated at 30°C with 90 mL of methanol/DMSO (1:1) for 30 min.
A bioanalytical method involving liquid-liquid extraction of diosmin from plasma samples was developed by Campanero M A et al. Plasma samples were incubated with β- glucuronidase/sulfatase to release diosmetin from its glucuronic acids conjugate. The analytes were

    Reduction involves increasing the number of carbon hydrogen bonds by adding hydrogen across a double or triple bond which results in an increase in electron density at the carbon atom. Organic functional groups containing double and triple bonds which undergo reduction are unsaturated. The reduction of the double bond by addition of hydrogen atoms results in the product being fully saturated. Metal hydride reducing agents that have different reactivities toward specific functional groups are commonly used in chemical reductions.…

    The motivation behind this experiment was to gain insight behind the theory and practice of two laboratory techniques: solubility-dependent extraction, and recrystallization, in an effort to isolate and identify three compounds originally dissolved in a mixture. Extraction is used to isolate a specific compound. Recrystallization involves taking a crude compound and removing unwanted impurities so that a more accurate melting point can be taken, leading to a more precise identification of a compound. The overarching goal was to isolate and identify three different unknowns in a given sample using these techniques. There are two types of extractions; solid-liquid extractions involve extracting a soluble compound from an insoluble (solid) material…

    In this lab, benzoic acid, benzocaine, and 9-fulorenone are isolated from a three-component mixture by using the acid-base extraction and other following types of various extraction techniques. An acid-base reaction is utilized in order to isolate the individual species from the mixture. First, in isolating the base benzocaine, proton transfers occurred via reaction with hydrochloric acid, which led to a significant shift in the polarity of the said compound, although the conjugate acid of benzocaine formed as a result. Due to the change in polarity, the state of benzocaine shifted from being solubilized in diethyl ether to water.…

    In this experiment, unknown B was a solid mixture containing two compounds of interests, 1,4-dimethoxybenzene and neutral benzoic acid. These compounds were separated by extraction and washing, and liquid-liquid extraction was specifically performed. Extraction is the process by which a compound of interest is selectively removed from impurities, and washing is the process by which unwanted products or impurities are selectively removed from the desired product. In liquid-liquid extraction, unknown B was dissolved sequentially into two immiscible liquids via a separatory funnel.…

    The physiochemical properties of this combination tablets were assessed through the evaluation of uniformity of tablet weight, thickness test, hardness test, friability test,disintegration test, dissolution test and potency test according to the standard method. They have generally two type of test. First compendial test and another one in non compendial test. Compendial tests are test methods that are described in the pharmacopoeias like United States Pharmacopeia (USP), British Pharmacopoeia (BP) etc. They are also known as official tests.…

    After starting with 30 mL of an unknown mixture of two solvents, fractional distillation and gas chromatography were used to identify the unknowns as acetone and toluene in a 1 to 2.04 ratio of acetone to toluene. Fractional distillation was first used to separate the unknown mixture into its components based on boiling point. Distillation refers to the method of separating components of a mixture through heating and cooling. Simple distillation, which is especially useful in the separation of less-volatile substances from volatile substances, such as sugar from water, can be used to separate a liquid-liquid mixture if the boiling points of the component liquids differ by more than 40-50°C. A plot of temperature versus volume for a simple…

    Certain medications may be indicated in different forms based on the patient’s needs and abilities. The most common dosage form is a tablet, which is a ‘pill’ typically taken orally as directed, but some patients such as children, the elderly and those who are recently recovering from oral surgery may find a tablet difficult to swallow, literally. For those who do have difficulty swallowing, a liquid form of the medication called a solution, may be a more suitable way to take the medication although, some medications are not available in a liquid form. Some medications require a coat of gelatin to surround the actual medication, so the medication will not innterphere with or be lost through the digestive process. These medications are referred to as capsules, and while they are not as easy to swallow as solutions they are easier to swallow than a tablet and may be beneficial to the patient.…

    In this lab, we carried out a variety of reactions using different chemicals and metals. A chemical reaction is when the chemical state of the substance you are testing rearranges its ionic and molecular structure. One of the reactions we experienced was single replacement, this consists of one ion switching places with another ion to form a new compound. Another reaction we saw was double replacement. In this reaction, two compounds ions are switched to form two new compounds.…

    MDMA (3,4-methylenedioxymethamphetamine), commonly referred to as ecstasy, and methamphetamine are central nervous system stimulants, which can produce euphoria, enhanced mental and emotional clarity, sensations of lightness and floating, and other hallucinations. (Chandra et al. 2015) Due to their effects, MDMA and methamphetamine are used in Drug-Facilitated Crimes (DFC), intended to impair behaviour, perceptions, or decision-making capacity to take advantage of an impaired person without their consent. In fact, the National Institute on Drug Abuse (NIDA) proved that young women under the influence of MDMA were more likely to have sex with men they had not intended to, as amphetamines increase sexual desire and lower inhibitions.
