Plumbago Zeylanica Lab Report
1. Introduction
Plumbago zeylanica L. (Plumbaginaceae) is an important medicinal plant greatly valued in Ayurveda for treatment of cough, asthma and gastrointestinal disorders. In Sushrutha Samhitha it has been described as antiseptic, febrifuge, detoxicant, antihelminthic and considered valuable for curing migraine, jaundice, urinary calculi, internal abscesses, seminal weakness, vaginal discharges and insanity. In the Arabian Peninsula, it is mainly distributed over Oman, Yemen and the Southwestern region of Saudi Arabia. The use of the roots of P. zeylanica for treating skin problems has been recorded by early Muslim physicians (Ghazanfar, 1994). The hepatoprotective, anti-inflammatory, anti-diabetic, anti-cancer and anti-hyperlipidemic

GC-MS analysis of the diethyl ether extract of the selected drugs was carried out on a 5975C Agilent system equipped with a DB-5ms Agilent fused silica capillary column (30 × 0.25 mm ID; film thickness: 0.25 μm), operating in electron impact mode at 70 eV. Pure helium (99.9995%) was used as carrier gas at a constant flow of 1.5 mL/min and an injection volume of 1 μL was employed (split ratio is 10: 1). Mass transfer line and injector temperature were set at 230°C and 250°C, respectively. The oven temperature was programmed from 70oC (isothermal for 2 min), with an increase of 10oC/min, to 3000C/min, ending with a 9 min isothermal at 3000C. The total running time for GC was 35 min. Mass spectra was taken at 70eV; with a scan range 40-700 m/z. Solvent cut time was 3 min; MS start time being 3 min; MS end time being 35 min; Ion source temperature set to 2300C and interface temperature being 2400C. To identify the compounds, the extract was assigned for comparison of their retention indices and mass spectra fragmentation patterns with those stored on the computer library and also with the published literature. National Institute of Standards and Technology library sources (NIST II) were used for matching the identified compounds from the plant materials (McLafferly and Stauffer, …show more content…
The blood was collected from the retro-orbital plexus on 10th day from animals and they were anesthetized using sodium phenobarbitone (60 mg/kg). The serum was separated by centrifugation at 1000 rpm for 10 min and analyzed for biochemical parameters such as serum urea, uric acid and electrolytes. Serum urea was measured using the commercially available kit (Liquicheck AGAPPE Diagnostics LTD), following the GLDH-Urease method (Tietz, 1976). The amount of creatinine in serum was estimated using Liquicheck AGAPPE Diagnostics commercial kit according to Picrate method (Cook, 1975). Serum uric acid level was determined using commercially available Biosystems Uric acid kit by Uricase method (Fossati et al., 1980). Estimation of serum sodium and potassium was done by flame photometric method (Chuang et al.,

    In this laboratory assignment, the spectroscopy data and molecular formula were given for 3 unknowns. An effort was made to conclusively identify these unknown samples using only the spectroscopy data, specifically 1H-NMR, 13C-NMR, and IR spectroscopy. Although mass spectrometry was given for the samples as well, its use was suggested only for confirmation, not identification, of the unknowns. Mass spectrometry was not included in the identification analysis of the compounds, however was used for confirmation of unknown #46. The spectroscopic data was analyzed using standard techniques, and the identity of the unknown samples were…

    Blue Hydrate Lab Report

    Conclusion: The purpose of this lab was to visually see the chemical change that was taking place when hydrates gain and lose water.The formula for blue hydrate is anhydrous copper (ii) sulfate (CuSO4). The percent error for the mass of water is -94.40%. The effect of the hydrate not being heated long enough would result in water still being in the hydrate. If the test tube was not dried completely prior to the initial measurement it would cause the data to follow that incorrect measurement to be false and it would also add more water into the hydrate than what was initially projected. If the anhydride was allowed to sit over before the final mass measurement was taken it would result in more water loss from the hydrate. The moles of CuSO4…

    The purpose of this lab was to identify an analgesic drug and to understand how to interpret infrared spectroscopy. The lab consisted of several steps, which include extraction, distillation and filtration. Based on the active ingredient crystals that were obtained at the end of filtration, the melting point was found. The active ingredient percent recovery was calculated and compared to the manufacturers claims. Next, the Rf value of the active ingredients were found through a TLC plate and compared to the standard of the drug. From these processes, the understanding of how organic compounds can be isolated and identified was possible. Although the infrared spectroscopy was not completed, the understanding and matching of structures with their proper IR spectra was still necessary. The main functional group peaks were used to distinguish several IR spectrums; these peaks mostly occur between 1600-4000 cm^-1.…

    The pGLO lab is a lab where students attempt to put the genes that make a jelly fish glow into E. Coli. After a process called transformation, the process in which a cell takes up and expresses a new piece of genetic information, the E. Coli will be able to glow and will be antibiotic resistant. The students first need to learn a couple of techniques before they are able to begin this lab. The first technique they will need is how to keep their environment sterile. They must learn to only open their tools, and other supplies for as long as they need, and keep them from touching anything. They must also learn that tools can never be shared between specimens, and when they use a tool, they should dispose of it and get a new one. Next they need to learn how to transfer a bacterial colony. To do this, one must use a sterile loop and scrape one colony off of the dish. Then they must insert the loop into…

    Thin-layer Chromatography(TLC) was the method used to figure out and identify the drug. TLC is done on a plate that is coated with a layer of absorbent material.after the solutions have been spotted onto the plate, a solvent is then drawn up the plate with capillary action. Capillary action has to do with the intermolecular forces with the liquid and the surroundings solid surface Different substances ascend the plates with different rates. After the TLC was completed the retention factors of each spot was then calculated. The retention factor(Rf) is calculated by the distance traveled by the sample then divided by the solvent. The retention factors of the 5 components were then compared of the unknown retention factors.…

    Solid C Synthesis

    Analysis of the C13-NMR for liquid C showed 5 distinctive peaks in the range of 0-80 ppm and one peak around 170 ppm indicating a carbon skeleton consisting of six carbons. The four peaks at 30.34ppm, 20.41ppm, 18.77ppm, and 13.25ppm are representative of primary and secondary alkyl carbons. Additionally one peak 63.82ppm strongly indicates an ether functional group and the remaining peak at 170.53ppm is representative of an ester carboxyl functional group. In terms of the analysis for the H1-NMR, several peaks were present that mimicked the types of functional groups present in the C13-NMR. Such includes peaks from 0.4-1.5ppm that are representative of primary and secondary alkyl functional groups, and peaks at 3.921ppm, 3.899ppm, and 3.876ppm which are strongly indicative of an ether functional group. After analysis of the IR spectrum, further confirmation of the functional groups found in the H-NMR and C-NMR were seen in the IR. Such peaks include multiple variable peaks ranging from 1200-1300cm-1 that show a Csp2-O oxygen bond that can be inferred for the ether functional group. Additional characteristic peaks include peaks ranging from 1680-1750cm-1 that represents a ketone functional group is present, and a broad sharp peak ranging from 3200-3559cm-1 which is indicative of concentrated alcohols and phenols. This is, however, not supported by the NMR spectra, and hence suggests the presence of impurities, especially in regards to the concentrated alcohol and phenol peak. The boiling point of butyl acetate is 126C according to literature. However, the boiling point observed during distillation was 117C, a lower measurement likely due to the presence of impurities as suggested by the IR…

    The tribal knowledge as regards use of plant species for various purposes depends on the surrounding plants. With the rapidly advancing process of civilization and urbanization, there is an imminent damage of losing forever these valued treasures of information. Simultaneously, the knowledge about ethnic therapies should also be restored and maintained, as this provides enormous data regarding the medicinal properties of plants not known to the modern men (Jain SK, 1999; Maheshwari JK, 1983; Jain SK et al.,…
