Physiochemical Evaluation Of Turmeric Oil Lab Report
CHAPTER 4

Uses Harmonic Mean Sample Size = 3.000 Values are mean±±SD of three independent determinations.
As discussed earlier, the extraction of the turmeric powder was done using various solvents at different temperatures. Different solvents provided extracts with different colour values at varying temperatures. At 50⁰C, the maximum colour value was found to be in the extract obtained using ethanol as the solvent. As shown in Figure 4.5, it could be clearly analyzed that different colour values are obtained on extraction with different solvents. Ethanol gave the maximum colour value i.e. 308.6; chloroform gave a slightly less value of 296.6; followed by methanolic extract giving 249.3 …show more content…

4.6 Antioxidant activity
DPPH scavenging activity
Figureure14 shows the DPPH radical scavenging activity of turmeric rhizome essential oil. Various concentrations of the oil were evaluated for their DPPH radical scavenging activity. The estimated IC50 values for the oil were found to be 3.1725 mg/ml and that of standard compound gallic acid is 1.38µg/ml and is inversely related to antioxidant capacity. This value was closely related to the IC50 values 3.227mg/ml found by Priya and co-workers in 2012. Figure 4.10 % Inhibition by …show more content…
It resulted in 20.11% curcumin with 337.6 color value. While comparing the dependence of the curcumin content, the results obtained with ANOVA proved that the solvent used had more impact than the temperature at which the extraction was carried out. The yield from hydrodistillation was 3.92%. GC-MS of the turmeric oil revealed that its chief components were Ar-tumerone and Curlone. Antioxidant and antimicrobial properties of turmeric oil and ethanol extract were compared, and the obtained results demonstrated that ethanolic extract of turmeric has more antimicrobial and antioxidant properties than turmeric

    Essential Oil Research Papers

    The use of essential oils began in the nineteenth century being used as flavour and aroma enhancers and quickly became popular. Since then they have become widespread over several industries pharmaceutical, cosmetic, medicinal and in food. There are 300 of the 3,000 different essential oils known being used commercially. As the synthetic preservatives became widely used because of their cheap production and relentless antimicrobial activity the use of essential oils as preservatives became less common and less studied. Nowadays synthetic preservatives such as parabens are frowned upon their use and products containing them will not be bought for fear of their health issues. The over use of antibiotics has led to microbial resistance against…

Studies show that turmeric may help fight infections and some cancers, reduce inflammation, and treat digestive problems, and it has gotten a lot of press lately. But remember several facts when you hear news reports about turmeric. First, many studies have taken place in test tubes and animals, and turmeric may not work as well in humans. Second, some studies ing evidence. Turmeric is widely used in cooking and gives Indian curry its flavor and yellow color. It is also used in mustard and to color butter and cheese. Turmeric has been used in both Ayurvedic and Chinese medicine as an anti-inflammatory, to treat digestive and liver problems, skin diseases, and wounds. Turmeric is also a powerful antioxidant. Antioxidants scavenge molecules in the body known as free radicals, which damage cell membranes, tamper with DNA, and even cause cell death. Antioxidants can fight free radicals and may reduce or even help prevent some of the damage they cause. In addition, turmeric lowers the levels of two enzymes in the body that cause inflammation. It also stops platelets from clumping together to form blood clots.…

    turmeric

    c) Characteristics of plant: Turmeric is a tropical plant, which forms many long thin rhizomes (roots) used to produce spice and dye. Cooke, T. (1908). It is a herbaceous plant, which means that leaves and stems die down in the end of the growing season. It grows over the spring and summer and dies every winter and autumn. Turmeric is also characterized by its pale, clustered flowers. Typically, it attains a height of about 1 meter or 4 feet. Its leaves are elongated, dark green, and pointed. The flower is bright yellow, 3cm long and 4cm wide. The outer skin of the plant is brownish, but its flesh is deep orange-yellow inside. Rhizomes grow in a horizontal manner. Each piece of rhizome has the ability to give a new plant. The process is called vegetative reproduction. When bruised, the Turmeric plant has a natural ability to exclude a spicy scent. The reddish-yellow flowers are arranged spirally and appear among the leaves directly rising from the rootstock. Graham, J. (1839).…

    TED CASE STUDIES TURMERIC Mfm

    Turmeric is a tropical herb grown in East India, and the powdered product made from the rhizomes of its flowers has several popular uses worldwide. Turmeric powder, which has a distinctive deep yellow color and bitter taste, is used as a dye, a cooking ingredient, and a litmus in a chemical test, and has medicinal uses as well. In the mid-1990s, this product became the subject of a patent dispute with important ramifications for international trade law. A U.S. patent on turmeric was awarded to the University of Mississippi Medical Center in 1995, specifically for the "use of turmeric in wound healing." This patent also granted them the exclusive right to sell and distribute turmeric. Two years later, a complaint was filed by India's Council of Scientific and Industrial Research, which challenged the novelty of the University's "discovery," and the U.S. patent office investigated the validity of this patent. In India, where turmeric has been used medicinally for thousands of years, concerns grew about the economically and socially damaging impact of this legal "biopiracy." In 1997, the patent was revoked. But for two years the patent on turmeric had stood, although the process was non-novel and had in fact been traditionally practiced in India for thousands of years, as was eventually proven by ancient Sanskrit writings that documented turmeric’s extensive and varied use throughout India’s history. Many developing countries are concerned that the globalization of intellectual property rights under the WTO's TRIPs agreement, and the negative consequences it has for traditional indigenous knowledge and biodiversity.…

    Fatty acid composition of the oil extracted from raw white sesame seeds (RWS) is shown in Table (4): The most abundantly found fatty acids were 18:2 (linoleic acid) being 45.68%, followed by 18:1 (oleic acid) 35.83%. Other fatty acids were found in considerable amount are 16:0 (Palmitic acid) 9.15% and 18:0 (stearic acid) 6.90% for RWS. The results obtained are in agreement with those of the literature Teco Finance Export (2005). Compared with the white Sudanese variety studied by Elleuch et al. (2007), oleic and linoleic acids contents were lower than the obtained results in linoleic but higher than in oleic. They reported 43 and 35%, respectively, these were in agreement with these results. Also, when…

    Summary Of Curcuma Longa

    Curcumin derived from turmeric (Curcumin longa) is being used form thousands of years as a healing agent for variety of illnesses [3]. Research over the last few decades has indicated that curcumin is a potent anti-inflammatory agent with strong therapeutic potential against a variety of cancers [4]. A large number of in vitro and in vivo studies in both animals and man have indicated these activities. Safety evaluation studies indicate that curcumin is well tolerated at a very high dose without any toxic effects [5]. Most drugs currently available for the treatment of cancer have many constrain due to poor solubility and associated diminished bioavailability that leads to overdose toxicity apart from inefficient therapeutic action. In economic point of view, higher doses cost more expenses in the procurement for the beneficiary. As these drugs are obtained from natural resources, meeting out constant supply against the demand become difficult. Poor yield on purification is another issue that depends on expression of secondary metabolites by plants and physical stability of compounds[6] . Hence, global community seeks a drug with either high potency or efficient formulation for…
