TR-427: Turmeric Oleoresin (CASRN 8024-37-1) NATIONAL TOXICOLOGY PROGRAM Technical Report Series No. 427 TOXICOLOGY AND CARCINOGENESIS STUDIES OF TURMERIC OLEORESIN (CAS NO. 8024-37-1) (MAJOR COMPONENT 79%-85% CURCUMIN, CAS NO. 458-37-7) IN F344/N RATS AND B6C3Ft MICE (FEED STUDIES) U.S. DEPARTMENT OF HEALTH AND HUMAN SERVICES Public Health Service National Institutes of Health FOREWORD The National Toxicology Program (NTP) is made up of four charter agencies of the U.S. Department of Health and Human Services (DHHS): the National Cancer Institute (NCI), National Institutes of Health; *theNational Institute of Environmental Health Sciences (NIEHS), National Institutes of Health; the National Center for Toxicological Research (NCTR),Food and Drug Administration; and the National Institute for Occupational Safety and Health (NIOSH), Centers for Disease Control. In July 1981, the Carcinogenesis Bioassay Testing Program, NCI, was transferred to the NIEHS. The NTP coordinates the relevant programs, staff, and resources from these Public Health Service agencies relatingto basic and applied research and to biological assay development and validation. The NTP develops, evaluates, and disseminates scientific information about potentially toxic and hazardous chemicals. This knowledge is used for protecting the health of the American people and for the primary prevention of disease. The studies described in thisTechnical Report were performed underthe direction of the NIEHS and were conducted in compliance withNTP laboratory health and safety requirements and must meet or exceed all applicable federal, state, and local health and safety regulations. Animal care and use were in accordance with the Public Health Service Policy on Humane Care and Use of Animals. The prechronic and chronic studies were conductedin compliance with Food and Drug Administration (FDA) Good Laboratory Practice Regulations, andaall aspectsof the chronic studies were subjected to retrospective quality assurance audits before being presented for publicreview. These studies are designed and conducted to characterize and evaluate the toxicologic potential, including carcinogenic activity, of selected chemicals in laboratory animals (usually two species, rats and mice). Chemicals selected for NTP toxicology and carcinogenesis studies are chosen primarily on thebases of human exposure, level of production, and chemical structure. Selection per se is not an indicator of a chemical's carcinogenic potential. These NTP Technical Reports are available for salefrom the National Technical InformationService, U.S. Department of Commerce, 5285 Port Royal Road, Springfield, VA 22161 (703-487-4650).Single copies of this Technical Report are available without charge while supplies last from Central Data Management, NIEHS, P.O.

All comments must be received by December 15, 1996, for consideration for the First Supplement. ____________________________________________________________________________________ May 31, 1996 Spice Oleoresins DESCRIPTION Spice Oleoresins used in foods are derived from spices and contain the total sapid, odorous, and related characterizing principles normally associated with the respective spices. The oleoresins are produced by one of the following processes: (1) by extraction of the spice with any suitable solvent or solvents, in combination or sequence, followed by removal of the solvent or solvents in conformance with applicable residual solvent regulations (see General Requirements below), or (2) by removal of the volatile portion of the spice by distillation, followed by extraction of the nonvolatile portion, which after solvent removal is combined with the total volatile portion. Spice Oleoresins are frequently used in commerce with added suitable food-grade diluents, preservatives, antioxidants, and other substances consistent with good manufacturing practice, as provided for under Added Substances (see General Provisions). When added substances are used, they must be declared on the label in accordance with current U.S. regulations or with the regulations of other countries that recognize the Food Chemicals Codex. The Spice Oleoresins covered by this monograph are Oleoresin Angelica Seed Obtained by the solvent extraction of the dried seed of Angelica archangelica Linnaeus as a dark brown or green liquid.

It has been used in traditional medicine as a household remedy for various diseases, including biliary disorders, anorexia, cough, diabetic wounds, hepatic disorders, rheumatism and sinusitis. For the last few decades, extensive work has been done to establish the biological activities and pharmacological actions of turmeric and its extracts. Curcumin (diferuloylmethane), the main yellow bioactive component of turmeric has been shown to have a wide spectrum of biological actions. These include its anti-inflammatory, antioxidant, anticarcinogenic, antimutagenic, anticoagulant, antifertility, antidiabetic, antibacterial, antifungal, antiprotozoal, antiviral,anti-fibrotic, antivenom, antiulcer, hypotensive and hypocholesteremic activities. Its anticancer effect is mainly mediated through induction of apoptosis. Its anti-inflammatory, anticancer and antioxidant roles may be clinically exploited to control rheumatism, carcinogenesis and oxidative stress-related pathogenesis. Clinically, curcumin has already been used to reduce post-operative inflammation. Introduction golden hamsters. The Indian Solid Gold Turmeric 4. Curcumin also increases mucin secretion in rabbits.

In this regard, natural extracts of the Lamiaceae family, such as rosemary, have been studied because of its bioactive properties. Several studies have reported that rosemary extracts show biological bioactivities such as hepatoprotective, antifungal, insecticide, antioxidant and antibacterial. It is well known that the biological properties in rosemary are mainly due to phenolic compounds. However, it is essential to take into account that these biological properties depend on different aspects. Their use in foods is limited because of their odour, colour and taste. For that reason, commercial methods have been developed for the preparation of odourless and colourless antioxidant compounds from rosemary. Owing to the new applications of natural extracts in preservatives, this review gives a view on the use of natural extract from rosemary in foods and its effect on preservative activities. Specifically, the relationship between the structure and activity (antimicrobial and antioxidant) of the active components in rosemary are being reviewed.

  • Effect of Curcumin, Mixture of Curcumin and Piperine and Curcum (Turmeric) on Lipid Profile of Normal and Hyperlipidemic Rats
    The Egyptian Journal of Hospital Medicine Vol., 21: 145 – 161 December 2005 I.S.S.N: 12084 2002–1687 Effect of Curcumin, Mixture of Curcumin and Piperine and Curcum (Turmeric) on Lipid Profile of Normal and Hyperlipidemic Rats GHADA, Z. A. Soliman Lecturer of Biochemistry, Biochemistry Department, National Nutrition Institute, Cairo Abstract Curcumin is a polyphenolic, yellow pigment obtained from rhizomes of Curcuma longa (curcum), used as a spice and food colouring. The extracts have several pharmacological effects. We evaluated the effect of curcum, curcumin, and mixture of curcumin and piperine on plasma lipids in normal and hypercholesterolemic rats. A total of 270 rats, divided into 27 groups, were used. G1, G11: control, G2-G11: normal rats fed control diet supplemented with different levels of curcumin and curcum (G2-G6: 0.1%, 0.25%, 0.5%, 1.0%, 2.0% respectively, G7-G11: 1.67%, 4.167%, 8.34%, 16.67%, and 33.34). G12-G26: at first fed control diet supplemented with 2% cholesterol then G13-17, 21-25 fed a control diet supplemented with different levels of curcumin, and curcum [the same levels as G2-G11; G18-20 fed control diet supplemented with mixture of curcumin (0.1, 0.25, 0.5%) and piperine (20 mg/kg BW)], G12 was sacrificed before addition of studied materials, G26 were fed control diet. Lipid profile, triacylglycerol and phospholipids of plasma and organs as liver and heart were measured. Serum cholesterol (total, LDL-C, VLDL-C), triacylglycerol and phospholipids contents were elevated in cholesterol-fed rats, while HDL-C were decreased.

  • As the Industry Develops, Cannabis and CBD Producers Sail Into the Dangerous Shoals of Product Recalls
    As the Industry Develops, Cannabis And CBD Producers Sail Into the Dangerous Shoals of Product Recalls By: Richard M. Blau, Chairman Cannabis Law Group Now that the federal government has legalized hemp and defined lawful cannabidiol (CBD) produced from hemp, the market for CBD products has moved forward with exponential growth. In 2018, approximately $620 million worth of CBD products were sold in the United States. Popular economic advice platforms such as The Motley Fool report projections from economists and industry experts estimating future growth at approximately $24 billion by 2023. Growing CBD revenue from $620 million in 2018 to $23.7 billion by 2023 delivers a compound annual growth rate (CAGR) of 107%. While such statistics reflect a maturing market, so, too , do the arrival of product recalls. Recently, several CBD companies announced voluntary recalls of their products. Summit Labs’ Kore Organic Watermelon CBD Oil On May 12, 2020, Florida-based Summitt Labs, which produces a wide range of hemp-derived cannabidiol (CBD) products, announced a voluntary nationwide recall of its Kore Organic watermelon tincture after the Florida Department of Agriculture and Consumer Affairs conducted a test on a random sample and found high levels of lead. When ingested, lead can cause various symptoms such as pain, nausea and kidney damage; in prolonged exposure situations, lead poisoning has been shown to contribute to degraded brain functions. Summit Labs conducted its own test through an accredited, independent lab that found the lead levels in an acceptable range under state law. But, because the Florida officials found excess lead levels in the sample they tested, Summitt quickly moved to withdraw the product from retailers, who have been notified by phone and email.

  • Recipes for Success – Innovating the Pepper Oleoresin Production at Synthite
    Recipes for success – innovating the pepper oleoresin production at Synthite Summary This case examines the operations at Synthite oleoresin plant in Kerala, India. It discusses the problems that company faced in production of pepper oleoresin, one of its flagship products. The case traces the problems to the Make-to-stock production strategy and to several material flow practices at the plant. The case provides quantitative data to analyze Synthite’s inventory management, material flow and order lead times. The case outlines in brief the company approach to addressing the problems it faced and encourages student to think critically about issues and other solutions. Students are encouraged to use the accompanying Excel data sheets to calculate and analyze different production parameters. 1 Recipes for success – innovating the pepper oleoresin production at Synthite On a hot summer day, Aju Jacob wondered how best to deal with the high levels of inventory and the constant need to expedite orders at Synthite, a medium size spice business that his family founded.
