A New Way Forward For Cannabidiol (Cbd) And Other Hemp Products, Patrick Cournoyer

Oxford ICSB

The FDA announced that existing regulatory frameworks for foods and supplements are not appropriate for cannabidiol (CBD). Given the available evidence, it is not apparent how CBD products could meet safety standards for dietary supplements or food additives. A new regulatory pathway for CBD is needed that balances individuals’ desire for access to CBD products with the regulatory oversight needed to manage risks.

Oxford ICSB

Nerium oleander is a well-known medicinal plant used in the Mediterranean region and traditional Indian medicine (Ayurveda) against a variety of diseases, including cancer. We investigated a cold-water extract of N. oleander leaves for their anticancer activities in vitro and in vivo. The cytotoxicity testing in the Oncotest panel of tumor cell lines and concomitant COMPARE analysis showed a high degree of similarity to mitosis-inhibiting compounds. We verified this hypothesis by treating tumor cells transfected with a tubulin-GFP fusion cDNA construct and confocal microscopy as well as a biochemical tubulin polymerization assay. N. oleander showed a similar inhibition of tubulin …

African Plants In Jamaican Farms And Gardens, Thera Edwards

Oxford ICSB

Plants of all growth forms and regeneration strategies were introduced to Jamaica by European slavers and by Enslaved Africans. Some species such as Tamarind used to purify drinking water on ships arrived through purposes of practicality while others that such as yam and plantain were transported as food supplies on the ships or by the Enslaved Africans as tubers for planting in their countries of destination. Tuber crops proved to be invaluable in hurricane prone islands such as Jamaica as the underground tuber was left undamaged by the high winds of the storms. Other crops such as Plantain while not …

Fda Investigational New Drug (Ind) Applications, Cassandra Taylor

Oxford ICSB

Current Federal law requires that a drug be the subject of an approved marketing application before it is transported or distributed across state lines. Because a sponsor will probably want to ship the investigational drug to clinical investigators in many states, it must seek an exemption from that legal requirement. The IND is the means through which the sponsor technically obtains this exemption from the FDA. During a new drug's early preclinical development, the sponsor's primary goal is to determine if the product is reasonably safe for initial use in humans, and if the compound exhibits pharmacological activity that justifies …

Introduction To The Premarket Review Of Human Food Ingredients In The United States And Concepts In The Safety Assessment Of Novel Plant-Derived Ingredients, Troy Hubbard

Oxford ICSB

Premarket regulation of ingredients added to food is a key pillar ensuring the safety of food as it allows the opportunity to address potential safety concerns prior to consumer exposure. In the United States, food and color additives are substances that are intentionally added to food and are subject to pre-market approval by the Food and Drug Administration (FDA) and require a listing in the Code of Federal Regulations, unless the intended use of the substance is generally recognized as safe (GRAS), among qualified experts. GRAS is not an inherent property of a substance, as is often misunderstood; rather, it …

Natural Products In Food And Agriculture, Stephen O. Duke

Oxford ICSB

Before the National Center for Natural Products Research (NCNPR) existed, I was Director of a USDA weed management lab. Two of my interests were natural products as herbicides and the chemical ecology of weed/crop interactions (allelopathy). Dr. James McChesney and I had several conversations about his vision for the NCNPR on the University of Mississippi campus. I was very interested in becoming a part of this, as his plan was to have a USDA lab that would study natural products for use in food and agriculture as part of the center. The USDA Agricultural Research Service established the Natural Product …

Preventing Ingredient Adulteration To Maintain Botanical Integrity, Katie Banaszewski

Oxford ICSB

The growing popularity of botanical products combined with the challenges of the supply chain to meet the ingredient demand has created opportunities for dishonest companies to take advantage of their clients for financial gain. Suppliers and manufacturers must comply with cGMPs (current Good Manufacturing Practices), specifically when it comes to the basic requirements of properly identifying crude botanicals in whole, cut, or powdered form, as well as botanical extracts and essential oils. Despite this regulatory requirement, a large portion of botanical ingredients and products sold in the marketplace are adulterated. Popular ingredients in high demand are intentionally substituted, diluted, or …

Characterization Of Ashwagandha Using A Multi-Detector Approach, Vincent Sica

Oxford ICSB

Botanicals are complex mixtures that present unique analytical challenges. A multi-detector chromatographic approach can provide accurate, constituent-based data to ensure proper identification and quantification of botanicals. These data are often used to help drive in silico safety assessments to identify suspected toxicants and assess the potential for deleterious effects using structure activity relationships. To showcase this approach, ashwagandha extracts were characterized to determine authenticity and to guide the necessary toxicological studies. To ensure the full constituency of the extracts are evaluated, a multi-detector system (UHPLC-PDA-CAD-HRMS) was employed and subjected to a comprehensive chemical constituent identification (CCID) process. All of the …

Oxford ICSB

Dietary supplement current good manufacturing practice (cGMP) in the U.S. requires the establishment of quality parameters for each component used in the manufacture of a dietary supplement to ensure that specifications for the identity, purity, strength, composition, and limits on contaminants are met using scientifically valid methods of analysis. However, specifications for botanical extracts (including fungal and algal extracts) routinely include additional data that are not amenable to verification through analytical methods. Such descriptive information may include Plant to Extract ratios, which are ratios of the quantity of botanical article used in the manufacture of the extract to the quantity …

The True History Of Aloes And Beyond, Ben-Erik Van Wyk

Oxford ICSB

The recorded history of aloes dates back thousands of years, with early recordings in the Papyrus Ebers (ca. 1550 B.C.) and in Dioscorides’s Herbal (1st cent. A.D.). Aloe has been used as a two-in-one medicine, not only by early explorers but also as a material of strategic military importance, with the yellow juice effective against the stomach problems of an army on the march and the white juice (gel) used to treat the wounds of battle. Aloe vera is the correct name for the “true aloe”, as the specific epithet “vera” indicates. The origins of the plant are shrouded in …

One-Class Modeling For The Authentication Of Actaea Racemosa And Evaluation Of The Variation Between Botanical Reference Materials, James Harnly

Oxford ICSB

One-class modeling based on soft independent modeling of class analogy (SIMCA) is a simple but powerful method for comparing the chemical composition of botanical materials using non-targeted chromatograms (GC, LC) or spectra (IR, MS, NIR, NMR). The methodology is available on any commercial chemometric platform. Authentication is based solely on the characteristics of the botanical material of interest. Detection of adulteration is determined for each variable and requires no identification of adulterants. Some highly characterized botanical reference materials (BRMs) may account for species, cultivar, and year and location of harvest while more generic BRMs may have minimal characterization. All of …

The Effects Of Acute Hypoxia Exposure On Cognitive Function, John W. Sepko, Zakary Patrick, Parker Wilkerson, Madison Hulsey, Paul D. Loprizini

Neuroscience Research Showcase

Introduction: There is conflicting literature as to the effects of varying levels of hypoxia on cognition. Recent work by Loprinzi et al. (2019) demonstrated that moderate levels of hypoxia exposure increased memory (cognitive) performance. However, research investigating severe hypoxic exposure has shown immediate cognitive impairments (Nation, 2017). To reconcile these mixed findings, the present study aimed to investigate the extent to which varying levels of hypoxia affect cognition. Methods: Eighty-seven participants were recruited using convenience sampling at the University of Mississippi and completed a within-subject study design. The first lab visit was conducted for familiarizing the participant to the lab …
